1
00:00:03,030 --> 00:00:06,810
Stonehenge is one of the greatest
mysteries in ancient history.
2
00:00:07,150 --> 00:00:12,010
This would have been the most amazing
and ambitious project that anyone could
3
00:00:12,010 --> 00:00:13,010
imagine.
4
00:00:13,310 --> 00:00:19,310
Created 5 ,000 years ago, generations of
experts have studied Stonehenge, but
5
00:00:19,310 --> 00:00:22,870
its construction and purpose still
remain a mystery.
6
00:00:23,410 --> 00:00:27,350
It's just magical, isn't it? You know,
just the simple thing of how did they
7
00:00:27,350 --> 00:00:28,189
build it?
8
00:00:28,190 --> 00:00:29,870
So now we're curious.
9
00:00:30,400 --> 00:00:34,920
Could we recreate this legendary
masterpiece with today's technology?
10
00:00:35,440 --> 00:00:39,060
I do think this kind of project would
attract a certain type of person.
11
00:00:39,460 --> 00:00:42,880
If I had a thousand people working with
me, I don't think I could build
12
00:00:42,880 --> 00:00:43,880
something like that.
13
00:00:44,700 --> 00:00:45,700
Here's the plan.
14
00:00:46,160 --> 00:00:51,360
We're rounding up the best engineers,
archaeologists, and logistics experts to
15
00:00:51,360 --> 00:00:54,300
help us build our own iconic monument.
16
00:00:55,440 --> 00:01:00,420
Even more colossal, awe -inspiring, and
built to last.
17
00:01:00,740 --> 00:01:04,300
There's an old army expression,
actually, that says amateur talk tactics
18
00:01:04,300 --> 00:01:05,600
professionals talk logistics.
19
00:01:09,760 --> 00:01:15,080
Imagine. The world's greatest wonders
reimagined.
20
00:01:15,580 --> 00:01:18,780
We're wondering, how long would it take?
21
00:01:19,520 --> 00:01:20,880
How much would it cost?
22
00:01:21,860 --> 00:01:24,260
How many workers would we need?
23
00:01:24,860 --> 00:01:27,260
Could we even do it?
24
00:01:27,960 --> 00:01:30,660
If we built it today.
25
00:01:39,700 --> 00:01:45,060
Situated on Salisbury Plain in southern
England, this puzzling ring of stone
26
00:01:45,060 --> 00:01:48,120
slabs has baffled researchers for
centuries.
27
00:01:49,680 --> 00:01:53,700
Stonehenge just has that kind of
breathtaking,
28
00:01:54,670 --> 00:01:55,670
aspect to it.
29
00:01:56,250 --> 00:01:59,150
It makes the hairs on the back of your
neck stand up.
30
00:02:00,830 --> 00:02:04,290
Well, I think everybody tends to find
Stonehenge fascinating both because it's
31
00:02:04,290 --> 00:02:10,550
very old and the people that far back in
time could build something that's so
32
00:02:10,550 --> 00:02:11,790
incredibly complicated.
33
00:02:13,010 --> 00:02:18,750
So complicated that some theorists have
credited its construction to giants,
34
00:02:19,030 --> 00:02:22,690
Merlin the Magician, and even aliens.
35
00:02:23,500 --> 00:02:27,920
Even today, how it was built and why is
still under debate.
36
00:02:28,760 --> 00:02:33,920
Archaeologist Michael Parker Pearson and
researcher Barney Harris have studied
37
00:02:33,920 --> 00:02:37,380
the mysteries behind Stonehenge's
construction extensively.
38
00:02:38,000 --> 00:02:43,900
We see the rise in the sense of
prehistoric mysteries and all sorts of
39
00:02:43,900 --> 00:02:47,220
outrageous theories about spacemen and
aliens.
40
00:02:48,150 --> 00:02:52,670
constructing civilizations on Earth
because humans simply weren't considered
41
00:02:52,670 --> 00:02:53,569
to it.
42
00:02:53,570 --> 00:02:58,150
There's a playfulness to it because it's
just these cartoonishly large stones
43
00:02:58,150 --> 00:03:03,330
and this enormous burning question of
how was this done and why was this done?
44
00:03:03,990 --> 00:03:09,830
It must have been built for the
ancestors because that's what we do with
45
00:03:09,830 --> 00:03:15,650
monuments. Stone is durable and eternal
to represent, in fact, to even become
46
00:03:15,650 --> 00:03:16,810
the ancestors.
47
00:03:19,630 --> 00:03:24,410
In terms of its function, some of the
beauty of prehistory is just that space,
48
00:03:24,730 --> 00:03:28,770
that lack of evidence to allow
creativity.
49
00:03:29,010 --> 00:03:31,210
You know, that's part of the enchantment
of it.
50
00:03:31,610 --> 00:03:37,670
So just how did ancient people construct
this colossal monument without access
51
00:03:37,670 --> 00:03:38,670
to modern tools?
52
00:03:39,310 --> 00:03:40,590
First things first.
53
00:03:40,890 --> 00:03:42,510
Let's start with what we know.
54
00:03:42,830 --> 00:03:46,430
The site's construction began around
3100 BCE.
55
00:03:47,530 --> 00:03:49,650
and took over a thousand years to
complete.
56
00:03:49,990 --> 00:03:56,330
On average, the stones weigh about 25
tons and measure about 30 feet long.
57
00:03:56,730 --> 00:04:00,690
Evidence suggests the prehistoric ruin
was built in stages.
58
00:04:01,150 --> 00:04:07,270
The first and oldest part of Stonehenge
is a massive circular ditch, or
59
00:04:07,270 --> 00:04:13,190
henge. The actual hinge itself is
basically just a big circular trench
60
00:04:13,190 --> 00:04:17,430
dig the soil and rock out. We know that
was done using picks made from deer
61
00:04:17,430 --> 00:04:22,250
antlers and shovels made from the
shoulder blades of oxen. And we know
62
00:04:22,250 --> 00:04:24,030
because they left those in the bottom of
the holes.
63
00:04:25,490 --> 00:04:30,670
Within the ditch was a ring of 56 pits,
or holes, dotted around the site's
64
00:04:30,670 --> 00:04:34,730
perimeter, forming a circle 905 feet
across.
65
00:04:35,770 --> 00:04:38,350
The exact purpose of the holes remains a
mystery.
66
00:04:39,550 --> 00:04:44,170
But some historians believe that they
were initially used to support wooden
67
00:04:44,170 --> 00:04:45,170
posts.
68
00:04:46,050 --> 00:04:50,650
For several hundred years, Stonehenge
remained largely untouched.
69
00:04:51,110 --> 00:04:57,670
Then, suddenly, around 2500 BC, the blue
stones started to arrive.
70
00:04:58,330 --> 00:05:04,030
Nearly 80 blue stones, weighing between
two to five tons each, were set up in
71
00:05:04,030 --> 00:05:05,830
two concentric half circles.
72
00:05:06,110 --> 00:05:09,630
But the Neolithic builders were far from
finished.
73
00:05:10,030 --> 00:05:11,790
It's when they bring in the big ones.
74
00:05:12,010 --> 00:05:17,250
And those are what we call sarsen
stones. It's a kind of cemented
75
00:05:17,650 --> 00:05:24,310
At some point, 30 massive sarsen stones,
weighing up to 50 tons, were brought in
76
00:05:24,310 --> 00:05:26,950
and arranged into the famous outer
circle.
77
00:05:27,480 --> 00:05:32,600
A horizontal structure known as lintels
was then placed on top of the sarsen
78
00:05:32,600 --> 00:05:38,440
stones. Well, at the same time, builders
also created what would become known as
79
00:05:38,440 --> 00:05:39,740
the inner circle.
80
00:05:40,220 --> 00:05:44,820
You also have what's called sarsen
horseshoe, which is an arrangement of
81
00:05:44,820 --> 00:05:49,260
trilithons arranged in the center of the
site, forming roughly a horseshoe.
82
00:05:49,840 --> 00:05:54,880
And then the second major sarsen
construction element was the sarsen
83
00:05:56,430 --> 00:06:02,370
Which was a continuous ring of
trilithons running all around the
84
00:06:02,370 --> 00:06:08,030
site. That contained 30 uprights and 30
lintels to form, we think, a perfect
85
00:06:08,030 --> 00:06:14,250
ring. So how did all of these giant
stones, some weighing up to four tons,
86
00:06:14,250 --> 00:06:15,250
up at Stonehenge?
87
00:06:15,450 --> 00:06:17,370
And who brought them there?
88
00:06:17,730 --> 00:06:21,690
I think part of Stonehenge's appeal is
the fact we don't really know for sure
89
00:06:21,690 --> 00:06:24,710
exactly how it was built, why it was
built.
90
00:06:25,850 --> 00:06:31,610
To actually move stones that far, you've
really got to have decades of
91
00:06:31,610 --> 00:06:36,770
preparation. The ropes, the timbers, it
must have been a huge amount of work.
92
00:06:37,950 --> 00:06:43,210
Many modern historians and
archaeologists believe that several
93
00:06:43,210 --> 00:06:48,510
of people contributed to Stonehenge,
each undertaking a different phase of
94
00:06:48,510 --> 00:06:55,270
construction. New research points to
early Europeans originating in Turkey,
95
00:06:55,840 --> 00:06:59,340
and reaching the UK from what is now
Portugal.
96
00:07:00,260 --> 00:07:02,700
They were mostly agricultural groups.
97
00:07:03,080 --> 00:07:07,240
They farmed, they had domesticated
animals, as they did in a lot of parts
98
00:07:07,240 --> 00:07:09,920
Europe and the Near East and the Middle
East at that period in time.
99
00:07:11,020 --> 00:07:15,740
This is actually not much more than 240
generations ago.
100
00:07:16,140 --> 00:07:21,540
They were just like us in the way that
they looked and in aspects of how they
101
00:07:21,540 --> 00:07:22,580
lived and acted.
102
00:07:23,040 --> 00:07:25,160
The construction spanned centuries.
103
00:07:25,760 --> 00:07:30,920
And we may never know what drew
generations of people to continue
104
00:07:31,460 --> 00:07:36,460
How did that idea stay current and stay
important to people over such a long
105
00:07:36,460 --> 00:07:38,020
period of time? That's the real
question.
106
00:07:38,320 --> 00:07:39,600
That's difficult to answer.
107
00:07:41,760 --> 00:07:44,880
Probably originally it was just done by
passing the knowledge on from one
108
00:07:44,880 --> 00:07:48,100
generation to the next, just in an oral
tradition, to explain what they were
109
00:07:48,100 --> 00:07:49,100
actually doing.
110
00:07:49,880 --> 00:07:53,360
So, what would it take to build a modern
Stonehenge?
111
00:07:54,830 --> 00:08:00,570
a structure that would last more than 5
,000 years and continue to inspire awe
112
00:08:00,570 --> 00:08:01,570
for generations.
113
00:08:03,970 --> 00:08:09,010
Could we organize and execute its
construction as well as the ancients?
114
00:08:10,410 --> 00:08:12,790
Some say no way.
115
00:08:13,230 --> 00:08:18,910
There comes a point where that very
special kind of society just won't work
116
00:08:18,910 --> 00:08:21,510
because the nature of society changed.
117
00:08:23,080 --> 00:08:26,640
But others think a modern Stonehenge is
possible.
118
00:08:27,040 --> 00:08:31,540
It's going to take somebody who has a
real special interest in the science and
119
00:08:31,540 --> 00:08:33,200
the history of that project.
120
00:08:33,700 --> 00:08:36,460
There's a desire to build something to
impress everybody else.
121
00:08:36,700 --> 00:08:39,780
So if you can say I was the one who
actually was responsible for that thing
122
00:08:39,780 --> 00:08:43,220
being built, you're going to be a pretty
high status person in that society.
123
00:08:45,140 --> 00:08:49,460
Could we assemble a workforce willing to
take on this epic challenge?
124
00:08:50,420 --> 00:08:51,840
It's a massive undertaking.
125
00:08:53,240 --> 00:08:59,160
We need some rock -solid reasons to do
Stonehenge -style heavy lifting.
126
00:09:00,200 --> 00:09:02,660
If we built it today.
127
00:09:05,860 --> 00:09:11,180
We're imagining how we'd build a new
Stonehenge that would leave the famous
128
00:09:11,180 --> 00:09:12,200
in the dust.
129
00:09:12,460 --> 00:09:17,620
But before we work out how we'd build
it, we need to figure out why we'd build
130
00:09:17,620 --> 00:09:20,180
it. Yet, that very question.
131
00:09:20,830 --> 00:09:23,410
has stumped archaeologists for
centuries.
132
00:09:24,150 --> 00:09:30,990
Stonehenge has a surprising grip on
people throughout the world, and even as
133
00:09:30,990 --> 00:09:35,750
archaeologist who studies it, I find
that one of the greatest mysteries,
134
00:09:35,750 --> 00:09:41,470
it has just gripped the imagination like
no other prehistoric site.
135
00:09:42,030 --> 00:09:47,430
Over the years, archaeologists have
attempted to explain why Stonehenge was
136
00:09:47,430 --> 00:09:48,430
built.
137
00:09:48,630 --> 00:09:54,680
One theory... suggests that Stonehenge
is a giant astronomical calendar.
138
00:09:55,100 --> 00:09:58,680
For the people that lived there during
the time that Stonehenge was
139
00:09:59,020 --> 00:10:03,260
it would have been probably fairly
important as a timekeeping mechanism.
140
00:10:05,240 --> 00:10:10,640
People used to mark where the sun rose
and set, and because it was critical in
141
00:10:10,640 --> 00:10:14,780
the wintertime to ensure that the summer
was going to come back again, they
142
00:10:14,780 --> 00:10:16,440
would watch the rising point of the sun.
143
00:10:16,720 --> 00:10:20,940
As you got towards the solstice around
December 21st, typically, the sun would
144
00:10:20,940 --> 00:10:26,060
slow down, slow down, slow down, stop,
rise to the same point for a couple of
145
00:10:26,060 --> 00:10:29,560
days, and then start moving back towards
the north, ensuring it was actually
146
00:10:29,560 --> 00:10:30,560
going to come back.
147
00:10:31,000 --> 00:10:34,880
You can use it with reasonable certainty
to predict some types of eclipses,
148
00:10:34,880 --> 00:10:36,420
especially lunar eclipses.
149
00:10:37,260 --> 00:10:42,560
Others have speculated Stonehenge was
built as a gathering place to celebrate
150
00:10:42,560 --> 00:10:43,960
peace and unity.
151
00:10:44,540 --> 00:10:50,660
It's about the spirit of the place,
which has something unique about it that
152
00:10:50,660 --> 00:10:55,300
prehistoric people recognized, that that
was what drew them to this as being
153
00:10:55,300 --> 00:11:01,860
somewhere special, because it had this
remarkable alignment of the heavens and
154
00:11:01,860 --> 00:11:05,580
the earth. If you like, they might have
seen this as some kind of cosmic harmony
155
00:11:05,580 --> 00:11:07,660
in this very special place.
156
00:11:08,380 --> 00:11:13,660
What Stonehenge was, and is to this day,
is a crowd magnet.
157
00:11:14,250 --> 00:11:18,190
a place built by people for people to
come together.
158
00:11:18,950 --> 00:11:23,950
This wasn't just a local monument for
local people, but something that was
159
00:11:23,950 --> 00:11:29,630
attracting huge numbers from many
different parts of the island. You meet
160
00:11:29,630 --> 00:11:33,230
marriage partners, you form alliances,
you resolve conflicts.
161
00:11:33,970 --> 00:11:39,250
Even today, one of the most exciting
things about Stonehenge is the mystery
162
00:11:39,250 --> 00:11:40,250
surrounding it.
163
00:11:40,470 --> 00:11:46,250
However... A discovery made in the early
20th century led experts to their most
164
00:11:46,250 --> 00:11:48,590
conclusive explanation yet.
165
00:11:49,070 --> 00:11:53,030
There are definitely cremated human
remains that were found in the bottoms
166
00:11:53,030 --> 00:11:57,110
the post holes, dating from some of the
earlier periods of time.
167
00:11:58,950 --> 00:12:03,910
Excavations revealed the cremated
remains of up to 58 people, providing
168
00:12:03,910 --> 00:12:07,910
that this might actually be an ancient
burial site.
169
00:12:11,420 --> 00:12:15,160
and maybe in a symbolic place where
people would sort of come together
170
00:12:15,160 --> 00:12:18,120
it was the one structure that they had
all sort of contributed towards
171
00:12:18,280 --> 00:12:21,040
much in the same way that even today we
do that sort of thing.
172
00:12:21,720 --> 00:12:26,820
Given the connection with death at
Stonehenge, it was tempting to think
173
00:12:26,820 --> 00:12:31,600
of the motivating factors for people was
the memory of an individual or perhaps
174
00:12:31,600 --> 00:12:36,860
what that individual came to symbolise
in a wider sense.
175
00:12:37,880 --> 00:12:39,820
Further analysis of the remains.
176
00:12:40,270 --> 00:12:42,950
exposed an astounding piece of evidence.
177
00:12:43,470 --> 00:12:49,070
The majority are women. It's very
possible that we are seeing a complete
178
00:12:49,070 --> 00:12:52,490
in the gender politics of that society.
179
00:12:52,910 --> 00:12:58,310
So we have the very interesting
possibility that Stonehenge was actually
180
00:12:58,310 --> 00:13:00,710
masterminded by women.
181
00:13:01,090 --> 00:13:06,390
Clearly, Stonehenge may have served
several purposes, and no theory stands
182
00:13:06,390 --> 00:13:08,150
as more valid than the other.
183
00:13:09,840 --> 00:13:16,300
Whether its purpose was to keep track of
time, celebrate community, or represent
184
00:13:16,300 --> 00:13:17,440
female empowerment.
185
00:13:18,900 --> 00:13:23,620
Put together, that's more than enough
reason to build a new Stonehenge.
186
00:13:24,040 --> 00:13:25,900
So, let's do it.
187
00:13:27,060 --> 00:13:32,680
And since we want to do this right,
we'll need a sacred space and use
188
00:13:32,680 --> 00:13:34,160
designs and methods.
189
00:13:35,230 --> 00:13:41,070
will also match the human strength
required to carry massive stones
190
00:13:41,070 --> 00:13:47,690
miles. And that mission will guide every
decision we make on our modern -day
191
00:13:47,690 --> 00:13:53,230
Stonehenge. But before we can imagine
recreating Stonehenge, we need to decide
192
00:13:53,230 --> 00:13:54,890
where we build it.
193
00:13:56,730 --> 00:14:01,710
If Stonehenge is a calendar most
famously known for its alignment with
194
00:14:01,710 --> 00:14:06,620
winter and summer solstice, If our
Stonehenge is going to do the same
195
00:14:06,620 --> 00:14:13,260
timekeeping job, it needs to be built at
51 .789 degrees north.
196
00:14:15,340 --> 00:14:19,580
If you go east of England, that takes
you sort of through the Netherlands,
197
00:14:19,720 --> 00:14:24,820
Germany, Poland, through Russia, just
north of Mongolia, the very extreme
198
00:14:24,820 --> 00:14:28,400
northern part of China, and a little bit
down towards Vladivostok in Russia.
199
00:14:29,260 --> 00:14:30,780
So what are our options?
200
00:14:31,530 --> 00:14:33,330
You could build one in the southern
hemisphere.
201
00:14:34,010 --> 00:14:37,830
If you go to the same latitude south of
the equator, the only place where
202
00:14:37,830 --> 00:14:40,850
there's actually any land is the very
southern part of Patagonia.
203
00:14:41,150 --> 00:14:44,270
Chile, southern Chile, or southern
Argentina.
204
00:14:45,530 --> 00:14:48,630
There's another place in the northern
hemisphere that could work.
205
00:14:50,410 --> 00:14:56,670
It's about 60 miles north of Calgary,
Alberta, in the heart of what's called
206
00:14:56,670 --> 00:14:57,670
Badlands.
207
00:14:58,970 --> 00:14:59,970
It's a remote...
208
00:15:00,490 --> 00:15:06,450
Dramatic backdrop for a modern -day
Stonehenge. From the architecture, we're
209
00:15:06,450 --> 00:15:10,790
starting to get the idea that this is
perhaps an exclusive space, symbolically
210
00:15:10,790 --> 00:15:12,950
and physically separated from the rest
of the landscape.
211
00:15:14,650 --> 00:15:20,930
The Badlands are on the exact latitude
of Stonehenge and perfect for our modern
212
00:15:20,930 --> 00:15:22,790
-day eternal stone monument.
213
00:15:23,270 --> 00:15:28,690
We're sold, but we're not ready to get
rolling just yet.
214
00:15:29,480 --> 00:15:31,600
We've still got to find our workers.
215
00:15:32,040 --> 00:15:35,960
I do think this kind of project would
attract a certain type of person.
216
00:15:36,200 --> 00:15:40,780
And figure out how they moved all that
rock without alien intervention.
217
00:15:41,340 --> 00:15:45,200
It's just magical, isn't it? You know,
just the simple thing of how did they
218
00:15:45,200 --> 00:15:50,240
build it? And what materials would we
need to recreate the stone circle?
219
00:15:50,500 --> 00:15:55,820
We're talking really accurate
construction techniques here. It's
220
00:15:55,820 --> 00:15:57,040
us today to imagine.
221
00:15:57,850 --> 00:15:59,950
that level of precision being achieved.
222
00:16:00,430 --> 00:16:04,570
Luckily, we know a few experts that can
lead us in the right direction.
223
00:16:05,750 --> 00:16:08,430
If we built it today.
224
00:16:11,610 --> 00:16:15,150
We're imagining how we'd build
Stonehenge today.
225
00:16:16,470 --> 00:16:22,150
We know we'd want to replicate the
design, and we'd like to build it north
226
00:16:22,150 --> 00:16:25,330
Calgary, Alberta's dark badlands.
227
00:16:26,140 --> 00:16:28,060
So that leads to our next question.
228
00:16:28,260 --> 00:16:32,460
What materials would we use for our
modern -day Stonehenge?
229
00:16:33,380 --> 00:16:37,560
Would we extract sandstone and spot a
dolerite from a quarry?
230
00:16:38,040 --> 00:16:41,200
Or would we use a different kind of
material?
231
00:16:41,680 --> 00:16:46,840
Because for astronomy purposes, it could
really be built out of anything.
232
00:16:49,900 --> 00:16:53,880
The main thing is the actual positioning
of the things and having them at the
233
00:16:53,880 --> 00:16:57,080
right latitude. So, yes, you could make
it out of anything, including paper
234
00:16:57,080 --> 00:16:58,080
mache.
235
00:16:59,180 --> 00:17:03,720
Before we decide, we want to know where
the stones that make up Stonehenge came
236
00:17:03,720 --> 00:17:04,720
from.
237
00:17:04,940 --> 00:17:09,180
For many years, archaeologists believed
that the Tharsen stones were brought
238
00:17:09,180 --> 00:17:11,000
from a region 20 miles away.
239
00:17:13,400 --> 00:17:17,940
Yet, recent research has pinpointed the
specific area.
240
00:17:19,109 --> 00:17:24,530
We've just found out that they come from
15 miles to the north.
241
00:17:27,710 --> 00:17:34,510
They just wanted stone of a suitable
size and shape, and the
242
00:17:34,510 --> 00:17:36,990
nearest they could find it was where
they got it from.
243
00:17:37,310 --> 00:17:42,670
Unlike the sarsen stones, the bluestones
presented their own mystery, because
244
00:17:42,670 --> 00:17:45,930
there isn't any naturally occurring
bluestone nearby.
245
00:17:47,390 --> 00:17:53,310
However... Geological studies suggest a
potential source far to the west of
246
00:17:53,310 --> 00:17:55,670
Stonehenge, in Wales.
247
00:17:56,070 --> 00:18:00,950
What we've discovered is actually where
the vast majority of the Welsh stones
248
00:18:00,950 --> 00:18:02,770
come from is the Preseli Hill.
249
00:18:07,350 --> 00:18:13,690
Amazingly, these quarries in Wales are
nearly 175 miles away from
250
00:18:13,690 --> 00:18:16,130
Stonehenge. Even more amazingly...
251
00:18:16,540 --> 00:18:21,640
Recent excavations suggest that some of
the blue stones may have initially been
252
00:18:21,640 --> 00:18:26,260
part of a stone circle at Wan Mon in the
Purcelli Hills.
253
00:18:26,780 --> 00:18:33,200
It was here that we were able to
excavate two of the quarries supplying
254
00:18:33,200 --> 00:18:39,420
stones and we found the remains of a
dismantled stone circle.
255
00:18:39,900 --> 00:18:45,500
A stone circle that we have now dated
and which we know was put up
256
00:18:47,379 --> 00:18:48,379
Before Stonehenge.
257
00:18:49,960 --> 00:18:51,460
So now we're curious.
258
00:18:51,880 --> 00:18:57,100
Is there an easier way to build a modern
-day Stonehenge that doesn't involve
259
00:18:57,100 --> 00:18:58,880
dragging all that stone?
260
00:19:00,020 --> 00:19:04,600
A modern version of Stonehenge, although
making it out of rock would be quite
261
00:19:04,600 --> 00:19:08,000
impressive, I suspect if anybody
actually did that, they would just use
262
00:19:08,000 --> 00:19:11,680
concrete. Because we're really good at
working with concrete. You can just make
263
00:19:11,680 --> 00:19:13,000
a form to whatever shape you want.
264
00:19:15,070 --> 00:19:16,170
Concrete it is.
265
00:19:16,490 --> 00:19:21,750
We'd model Stonehenge in a computer and
use giant molds to shape the concrete
266
00:19:21,750 --> 00:19:23,570
for each individual stone.
267
00:19:25,290 --> 00:19:30,230
3D printed concrete is also an option,
the latest technique that's
268
00:19:30,230 --> 00:19:32,470
revolutionizing construction these days.
269
00:19:33,050 --> 00:19:38,730
But we still have to figure out how and
who is going to build this monument.
270
00:19:38,830 --> 00:19:42,530
This brings us back to what Stonehenge
might have been used for.
271
00:19:42,960 --> 00:19:47,420
Some archaeologists suggest that
Stonehenge was a gathering place.
272
00:19:47,820 --> 00:19:54,200
So, what if we turned our Stonehenge 2
.0 into an outdoor concert venue?
273
00:19:54,420 --> 00:19:56,860
How would our materials hold up?
274
00:19:57,120 --> 00:20:02,340
If we think of any ritual that we get
involved in, a wedding or a funeral or a
275
00:20:02,340 --> 00:20:05,180
christening, whatever it might be, it
involves sound.
276
00:20:05,960 --> 00:20:10,700
So understanding what the sound was like
in the past and how the stones might
277
00:20:10,700 --> 00:20:14,480
have affected that sound is really
important to understand the use of the
278
00:20:15,980 --> 00:20:21,020
Setting up an acoustics test on
Salisbury Plain isn't in the cards.
279
00:20:21,540 --> 00:20:27,840
So, acoustics engineer Trevor Cox
created a digital Stonehenge replica.
280
00:20:28,620 --> 00:20:32,120
If you were to go and measure Stonehenge
today, you'd get a very different
281
00:20:32,120 --> 00:20:36,200
acoustic response because so many of the
stones are missing or on the floor.
282
00:20:37,320 --> 00:20:41,720
I draw on archaeology, so I talked to,
in this case, Historic England, who
283
00:20:41,720 --> 00:20:45,600
actually had a computer model where they
had all the stones in their original
284
00:20:45,600 --> 00:20:46,600
configurations.
285
00:20:47,780 --> 00:20:53,720
Next, Trevor brought those computer
models to life with a 3D printer and
286
00:20:53,720 --> 00:20:55,720
them out in a soundproof chamber.
287
00:20:59,560 --> 00:21:04,240
It's vital that the stones are placed at
the right size, right shape, and placed
288
00:21:04,240 --> 00:21:08,700
in exactly the right place, because
we're working at 1 to 12 scale, so
289
00:21:08,700 --> 00:21:12,300
everything's shrunk by 12, so we've got
to get it into millimetre accuracy.
290
00:21:14,800 --> 00:21:18,820
So this test chamber has absorbent
walls, and that means any sound that
291
00:21:18,820 --> 00:21:22,920
the stone circle disappears and gets
absorbed by the walls. And that's like
292
00:21:22,920 --> 00:21:23,920
real Stonehenge.
293
00:21:27,240 --> 00:21:30,140
And the results were truly
extraordinary.
294
00:21:34,060 --> 00:21:37,680
I think the first surprise in what you
find in Stonehenge is it's got
295
00:21:37,680 --> 00:21:38,680
reverberation.
296
00:21:41,640 --> 00:21:45,940
The sound does linger a little while
before dying away. The reverberation
297
00:21:46,000 --> 00:21:48,560
which is what we measure, is about 0 .6,
0 .7 seconds.
298
00:21:50,460 --> 00:21:52,880
Remarkably, that reverberation time...
299
00:21:53,160 --> 00:21:57,060
is about the same as many of the world's
finest concert halls.
300
00:21:57,400 --> 00:22:02,280
It's half as good as the gold standard,
New York's famed Carnegie Hall.
301
00:22:02,540 --> 00:22:06,880
So the acoustic supports the fact that
this is a site where ceremonies could
302
00:22:06,880 --> 00:22:07,880
take place.
303
00:22:08,430 --> 00:22:12,210
What you learn from the acoustic study
is it tells you maybe a bit about the
304
00:22:12,210 --> 00:22:13,009
of the space.
305
00:22:13,010 --> 00:22:16,970
The fact that speech communication is
easier within the circle, the fact that
306
00:22:16,970 --> 00:22:20,970
music sounds better within the circle,
implies that anyone who was involved in
307
00:22:20,970 --> 00:22:23,990
the ceremony who was within that circle
was getting a pretty sound.
308
00:22:25,750 --> 00:22:31,190
And Trevor says 3D printing in concrete
is a perfect way to construct a great
309
00:22:31,190 --> 00:22:32,850
-sounding outdoor theater.
310
00:22:35,130 --> 00:22:37,070
He's already done it in miniature.
311
00:22:38,700 --> 00:22:42,600
If we actually print hollows, you then
have to backfill them with concrete,
312
00:22:42,720 --> 00:22:46,920
because from the acoustic perspective,
we're trying to mimic stone here, so we
313
00:22:46,920 --> 00:22:51,640
want it to be heavy and impervious, so
we actually fill the back of them up
314
00:22:51,640 --> 00:22:52,640
concrete.
315
00:22:53,360 --> 00:22:59,020
If Stonehenge is really an old
amplifier, it's centuries ahead of its
316
00:22:59,780 --> 00:23:03,480
People care about sound volume when they
need to communicate.
317
00:23:04,160 --> 00:23:10,030
And, as in any megalogistical project,
Communication is everything.
318
00:23:10,490 --> 00:23:15,570
So now we're ready to build it in sight
and sound.
319
00:23:16,170 --> 00:23:21,890
But we still need to figure out how to
get 3 ,000 tons of concrete to the
320
00:23:21,890 --> 00:23:22,950
Alberta Badlands.
321
00:23:23,370 --> 00:23:29,230
How do you move stones? Even if you've
got wooden sledges and thousands of
322
00:23:29,230 --> 00:23:32,090
willing helpers, it's a massive
undertaking.
323
00:23:32,730 --> 00:23:36,950
And to somehow raise it to the sky in a
perfect circle.
324
00:23:37,450 --> 00:23:42,230
This would have been the most amazing
and ambitious project that anyone could
325
00:23:42,230 --> 00:23:45,570
imagine. Can our team conquer the
seemingly impossible?
326
00:23:46,430 --> 00:23:48,910
If we build it today.
327
00:23:51,510 --> 00:23:55,710
We're exploring the secrets behind the
world's greatest prehistoric monument,
328
00:23:56,030 --> 00:23:59,250
Stonehenge, to find out how we'd build
it today.
329
00:23:59,850 --> 00:24:04,590
Of course, there's no denying the
original stands as an enduring testament
330
00:24:04,590 --> 00:24:09,690
the engineering skills of the Neolithic
people who created it nearly 5 ,000
331
00:24:09,690 --> 00:24:10,649
years ago.
332
00:24:10,650 --> 00:24:16,490
But, as it turns out, we're far from
being the first to take on this
333
00:24:16,890 --> 00:24:21,290
There have been people who have
replicated Stonehenge from various
334
00:24:21,470 --> 00:24:25,190
There's actually a refrigerator henge
where there's sort of a replica made of
335
00:24:25,190 --> 00:24:28,170
old dead refrigerators. There's ones
made out of old junk cars.
336
00:24:29,530 --> 00:24:35,570
Nigel Allen constructed his backyard
stone circle in Nova Scotia, Canada.
337
00:24:36,990 --> 00:24:42,250
This location was just in the field and
it was a perfectly flat circular space
338
00:24:42,250 --> 00:24:47,690
in the midst of rolling terrain going
down to the river. But this was a flat
339
00:24:47,690 --> 00:24:53,550
dime begging to have a circle stone put
around its perimeter.
340
00:24:55,590 --> 00:25:01,620
With a local quarry not far away, He
struck a deal to buy some big stones and
341
00:25:01,620 --> 00:25:02,860
broke ground.
342
00:25:03,320 --> 00:25:05,020
So I said, I've got an idea.
343
00:25:05,360 --> 00:25:11,620
So I marked a circle off, a radius with
a rope and done the circle, figured out
344
00:25:11,620 --> 00:25:16,000
where I wanted to put the stones, dug
holes for the stones, had them load them
345
00:25:16,000 --> 00:25:20,580
in one of their giant dump trucks, and
they would spin one at a time, dump it
346
00:25:20,580 --> 00:25:25,820
directly in front of the hole, and I'd
have one of the larger excavators come,
347
00:25:25,980 --> 00:25:28,840
and he would... Just grab the end of it
and tip it up.
348
00:25:29,140 --> 00:25:34,620
Nigel's stones weigh between 6 and 12
tons, half the size of the towering
349
00:25:34,620 --> 00:25:36,400
monsters at Stonehenge.
350
00:25:36,640 --> 00:25:43,140
And even they took a 15 -ton crane and a
massive excavator to do the job,
351
00:25:43,320 --> 00:25:47,220
machinery the folks who built Stonehenge
didn't have.
352
00:25:47,600 --> 00:25:51,000
The texture of the rock makes it look
ancient.
353
00:25:51,200 --> 00:25:55,880
The way it's rippled and weathered makes
it look like it's been here thousands
354
00:25:55,880 --> 00:25:56,880
of years.
355
00:25:57,070 --> 00:26:01,870
Two decades after building it, Nigel
Stonehenge has given locals in his quiet
356
00:26:01,870 --> 00:26:03,770
community something to talk about.
357
00:26:04,150 --> 00:26:08,750
There was a little reaction when the
stones went up so quickly. People were
358
00:26:08,750 --> 00:26:11,790
used to things changing out in the
middle of nowhere, so they were a little
359
00:26:11,790 --> 00:26:15,610
apprehensive, and it brought lots of
different types of people in.
360
00:26:16,350 --> 00:26:20,430
And it's given him an appreciation for
the skills of the ancient builders.
361
00:26:21,360 --> 00:26:26,460
Having done this and having come in
close contact with these huge objects,
362
00:26:26,460 --> 00:26:31,700
quite convinced that the people who have
come before were more resourceful,
363
00:26:31,700 --> 00:26:35,140
stronger, smarter, and had a better idea
how to do things.
364
00:26:36,120 --> 00:26:40,620
5 ,000 years ago, the ancient people
moved all that rock.
365
00:26:41,360 --> 00:26:47,060
But we still don't know how it got from
point A to point B without modern
366
00:26:47,060 --> 00:26:48,060
equipment.
367
00:26:49,230 --> 00:26:54,510
Historians used to think Stonehenge's
builders engineered some kind of log
368
00:26:54,510 --> 00:26:55,510
rolling system.
369
00:26:57,090 --> 00:27:02,810
So this notion has been persistently
explored by archaeologists, testing
370
00:27:02,810 --> 00:27:04,790
these rollers do really work the way
they're proposed.
371
00:27:05,170 --> 00:27:09,110
But when you look at the evidence, what
you find is that this idea doesn't
372
00:27:09,110 --> 00:27:10,270
really hold water.
373
00:27:10,730 --> 00:27:15,330
From a technical perspective, it's
difficult, because when you have
374
00:27:15,330 --> 00:27:20,440
rollers... You look on the ground around
us, the ground is uneven, there's
375
00:27:20,440 --> 00:27:21,440
bumps, there's lumps.
376
00:27:21,720 --> 00:27:25,260
This is going to set these rollers all
different directions. They're going to
377
00:27:25,260 --> 00:27:27,800
jamming into each other, moving across
each other.
378
00:27:28,000 --> 00:27:31,160
Any kind of hill, it's difficult to
negotiate it.
379
00:27:31,400 --> 00:27:37,560
So really, the rollers' idea should be
confined, I think, to the dustbin of
380
00:27:37,560 --> 00:27:38,560
history.
381
00:27:39,200 --> 00:27:41,780
So if we don't use log rollers...
382
00:27:42,280 --> 00:27:45,700
How are we going to move 3 ,000 tonnes
of concrete?
383
00:27:46,340 --> 00:27:51,700
A much more viable method, and certainly
one that we see represented as well
384
00:27:51,700 --> 00:27:58,060
ethnographically, is the idea that
stones were placed on sledges and then,
385
00:27:58,060 --> 00:28:02,100
necessary, some kind of trackway was
prepared for these sledges. Bits of
386
00:28:02,120 --> 00:28:07,020
bits of brush, bits of anything really
to just keep the sledge from biting into
387
00:28:07,020 --> 00:28:10,200
the ground and just pulled along in that
way.
388
00:28:10,920 --> 00:28:15,900
To put the debate to bed once and for
all, researcher Barney Harris and his
389
00:28:15,900 --> 00:28:21,220
colleagues from the University College
London tested alternative ways of moving
390
00:28:21,220 --> 00:28:23,660
large stones without rollers.
391
00:28:25,120 --> 00:28:31,000
And we explored two things. One was the
particular form of sledge that we see
392
00:28:31,000 --> 00:28:33,080
used in ethnographic accounts.
393
00:28:34,100 --> 00:28:37,700
And then the second thing we wanted to
investigate was the kind of tracking
394
00:28:37,700 --> 00:28:39,620
was needed to move this sledge.
395
00:28:40,220 --> 00:28:43,020
And we were interested in the idea of a
timber slipway.
396
00:28:46,180 --> 00:28:52,820
We started off with 30 or 40 students
pulling this sledge with the stone
397
00:28:52,820 --> 00:28:55,260
strapped to it, and that went well.
398
00:28:55,520 --> 00:28:59,720
And then towards the end, they managed
to sort of fine -tune it so there was
399
00:28:59,720 --> 00:29:03,820
about eight students managing to pull
this sledge with the stone on.
400
00:29:07,690 --> 00:29:12,430
The sledge simply slides across the top
of it, and this is a much more stable
401
00:29:12,430 --> 00:29:16,310
arrangement than log rollers, but does
still help reduce the friction.
402
00:29:16,630 --> 00:29:18,030
The sledge method it is.
403
00:29:18,430 --> 00:29:24,870
Now we can cross location, materials,
and equipment off our to -do list, but
404
00:29:24,870 --> 00:29:26,890
biggest challenge may lie ahead.
405
00:29:27,230 --> 00:29:29,890
How many people will we need to hire?
406
00:29:30,350 --> 00:29:34,670
Well, I think you would have a hard time
finding hundreds or thousands of...
407
00:29:34,810 --> 00:29:39,630
people, you would need to move a 20 -ton
rock day after day after day.
408
00:29:39,990 --> 00:29:44,070
How many people out there are going to
have the stamina and the strength to
409
00:29:44,070 --> 00:29:45,490
actually be able to do that?
410
00:29:46,050 --> 00:29:49,850
I suspect it may be a combination where
some people were actually paid and other
411
00:29:49,850 --> 00:29:51,450
people just volunteered.
412
00:29:52,410 --> 00:29:58,190
My guess is that you actually have
separate, probably geographically
413
00:29:58,190 --> 00:30:02,490
teams who are responsible for one part
of the circle.
414
00:30:03,080 --> 00:30:06,680
and that collectively they do this
together.
415
00:30:08,420 --> 00:30:14,300
We'll need an army and the right general
to lead it. Luckily, we have one of the
416
00:30:14,300 --> 00:30:16,040
world's best in mind.
417
00:30:16,400 --> 00:30:19,100
If we built it today.
418
00:30:21,760 --> 00:30:26,000
We're imagining how we'd build a modern
-day Stonehenge.
419
00:30:26,860 --> 00:30:27,860
So far.
420
00:30:28,160 --> 00:30:32,680
we figured out that we'd want to build
it north of Calgary, in Alberta's stark
421
00:30:32,680 --> 00:30:33,680
Badlands.
422
00:30:34,620 --> 00:30:41,420
We'd need to 3D print molds for 157
stones made of concrete, weighing
423
00:30:41,420 --> 00:30:43,420
over 3 ,000 tons.
424
00:30:44,080 --> 00:30:49,900
And to move all that heavy rock, we'll
employ a sledge system that reduces
425
00:30:49,900 --> 00:30:54,840
friction on the stone, allowing it to
move easier and faster.
426
00:30:56,150 --> 00:31:01,290
Experts estimate that it took nearly 10
million combined hours of labor to build
427
00:31:01,290 --> 00:31:05,710
the original Stonehenge. And that was
over 5 ,000 years.
428
00:31:06,650 --> 00:31:11,850
Today, thanks to technology, we're
hoping to cut that time down
429
00:31:12,390 --> 00:31:14,510
Which leads us to our next challenge.
430
00:31:16,170 --> 00:31:18,210
How many workers would we need?
431
00:31:18,430 --> 00:31:20,590
And where are we going to find them?
432
00:31:22,890 --> 00:31:28,130
The engineering of the project is the
easy part. No plumbing, no heat, no
433
00:31:28,130 --> 00:31:30,290
electrics, no building inspectors.
434
00:31:31,330 --> 00:31:38,050
With 157 stones, let's say 25 workers
per stone, for a total of 3
435
00:31:38,050 --> 00:31:43,030
,925 hands, and round up to 4 ,000.
436
00:31:43,250 --> 00:31:50,170
Multiply by 5 for complex jobs like our
modern Stonehenge, that's 20 ,000 people
437
00:31:50,170 --> 00:31:51,170
in total.
438
00:31:51,230 --> 00:31:56,630
Not impossible, but how do you keep them
around long enough to get the job done?
439
00:31:57,150 --> 00:32:00,330
If you're out on an operation, you're
going to need probably three to four
440
00:32:00,330 --> 00:32:02,930
supporters for every one operator on the
front line.
441
00:32:03,290 --> 00:32:07,610
Caleb McDonald is a logistics manager
with the Canadian Armed Forces.
442
00:32:08,070 --> 00:32:11,250
He plans massive operations for a
living.
443
00:32:11,820 --> 00:32:15,120
What we'd usually do is send in a sort
of a skeleton crew on the front end,
444
00:32:15,140 --> 00:32:18,740
which might be labor heavy, and they
have to sort of establish the groundwork
445
00:32:18,740 --> 00:32:22,020
for the rest of the technicians and the
soldiers to come in on the back end.
446
00:32:22,220 --> 00:32:27,120
And so what you'd see is laborers and a
few electricians, cooks, build out the
447
00:32:27,120 --> 00:32:30,500
accommodations area, set up power
generation and power distribution.
448
00:32:30,980 --> 00:32:34,280
So when the actual workforce arrives,
they have somewhere to live, they have
449
00:32:34,280 --> 00:32:37,520
something to eat, they have water to
drink, and they can go through all of
450
00:32:37,520 --> 00:32:39,780
functions they need to do in order to
get the work done.
451
00:32:40,250 --> 00:32:43,010
What kind of supplies would our mobile
workforce need?
452
00:32:43,490 --> 00:32:47,370
From a caloric perspective, we start
with 3 ,000 or 4 ,000 for manual labor.
453
00:32:47,830 --> 00:32:52,370
That's probably 150 to 200 loaves of
bread per day. And you do the same thing
454
00:32:52,370 --> 00:32:56,930
for fresh fruit. And you do the same
thing for meat and all those other
455
00:32:56,930 --> 00:32:59,850
commodities that you need soldiers to be
healthy and productive.
456
00:33:00,830 --> 00:33:05,010
Water being probably the most critical
of all the sort of commodities that we
457
00:33:05,010 --> 00:33:06,350
use to keep a camp running.
458
00:33:07,160 --> 00:33:12,260
Shelter, food and water for thousands of
people for a thousand years.
459
00:33:12,800 --> 00:33:19,540
We're on our way to assembling an epic
workforce backed by a top notch
460
00:33:19,540 --> 00:33:20,540
team.
461
00:33:20,920 --> 00:33:27,300
The challenges are simply motivating
that number of people to stay on task
462
00:33:27,300 --> 00:33:28,300
so long.
463
00:33:28,360 --> 00:33:32,160
And just like today, the pitch needs to
pack a punch.
464
00:33:33,050 --> 00:33:37,270
Recruiting is its own science, and part
of it is around selling what the
465
00:33:37,270 --> 00:33:38,270
adventure is.
466
00:33:38,430 --> 00:33:41,570
Because if we just said, yeah, your job
is going to be to dig holes for eight
467
00:33:41,570 --> 00:33:45,110
hours a day, come on out, we're hiring,
then we're not going to get anybody
468
00:33:45,110 --> 00:33:46,110
coming in.
469
00:33:46,210 --> 00:33:51,490
Social media expert Anita Kirkbride
thinks finding people would be easy.
470
00:33:52,430 --> 00:33:56,850
Organizing Stonehenge 2 .0 would be the
Internet event of the century.
471
00:33:57,610 --> 00:33:59,630
Well, with the click of a button on...
472
00:33:59,880 --> 00:34:04,560
pretty much every social network right
now, you could potentially connect with
473
00:34:04,560 --> 00:34:09,420
billions of people. To get people to
want to be a part of a big project like
474
00:34:09,420 --> 00:34:11,159
this, it's...
475
00:34:11,500 --> 00:34:13,739
Showing them how they can be part of a
community.
476
00:34:14,020 --> 00:34:19,719
The days of gathering a workforce
through unions, churches, and clubs are
477
00:34:20,020 --> 00:34:24,940
Anita thinks the time has never been
better to raise a social media -driven
478
00:34:24,940 --> 00:34:29,480
force. This kind of project would
attract a certain type of person,
479
00:34:29,480 --> 00:34:34,739
wants to see how things were done, the
people who are curious about how did
480
00:34:34,739 --> 00:34:38,179
people actually move these 20 -ton
rocks.
481
00:34:38,840 --> 00:34:43,420
And for some people, they won't believe
that people actually were able to do
482
00:34:43,420 --> 00:34:45,179
that until they participate in it.
483
00:34:46,380 --> 00:34:50,360
I could see the construction of
something like Stonehenge, the movement
484
00:34:50,360 --> 00:34:55,239
stones taking place on an annual basis,
with people coming together each year to
485
00:34:55,239 --> 00:34:59,380
move another stone and perhaps bundling
it in with a massive party.
486
00:34:59,780 --> 00:35:03,520
When the job goes viral, influencers
will line up.
487
00:35:04,160 --> 00:35:06,680
You could be doing live updates.
488
00:35:07,370 --> 00:35:08,730
to share what's happening.
489
00:35:09,010 --> 00:35:14,410
You could be showing the live footage of
people moving these 20 -ton rocks.
490
00:35:14,670 --> 00:35:18,350
Pretty much all of the social media now
have live streaming capabilities.
491
00:35:19,330 --> 00:35:24,830
You could have a really good group of
people helping you publicize this where
492
00:35:24,830 --> 00:35:26,550
they've got 2 million followers.
493
00:35:27,490 --> 00:35:33,310
So how long would this project take with
a first -class logistics team and an
494
00:35:33,310 --> 00:35:34,310
army of influencers?
495
00:35:35,240 --> 00:35:42,140
You can move maybe three miles a day.
For 180 miles, you could do that in a
496
00:35:42,140 --> 00:35:43,140
summer season.
497
00:35:43,240 --> 00:35:46,740
Cutting back on the thousand years it
took to build Stonehenge.
498
00:35:46,940 --> 00:35:47,980
No problem.
499
00:35:48,760 --> 00:35:52,120
It's going to have been done in less
than 10 years. That would be my guess.
500
00:35:52,660 --> 00:35:56,200
10 years isn't much worse than any other
modern mega build.
501
00:35:56,660 --> 00:36:02,480
So let's form our team and leave the
Stonehenge builders in the dust.
502
00:36:03,240 --> 00:36:05,320
But there's one burning question.
503
00:36:05,620 --> 00:36:10,220
Who's picking up the bill if we built it
today?
504
00:36:12,700 --> 00:36:19,000
We're rebuilding Stonehenge, reimagining
3 ,000 tons of stone
505
00:36:19,000 --> 00:36:25,340
in an outdoor venue built for thousands
of people, celebrating the power of
506
00:36:25,340 --> 00:36:29,280
women with a monument that will last an
eternity.
507
00:36:29,720 --> 00:36:32,160
And thanks to non -profit organizations,
508
00:36:32,960 --> 00:36:35,840
Construction volunteering is thriving.
509
00:36:36,960 --> 00:36:43,560
Over 13 million people have volunteered
their time to help build for people in
510
00:36:43,560 --> 00:36:46,300
need in the past half century.
511
00:36:46,880 --> 00:36:48,860
It's an extraordinary undertaking.
512
00:36:49,540 --> 00:36:55,180
It's going to be more than merely, let's
start at A and go to B.
513
00:36:55,870 --> 00:36:58,490
Because you're going to have people all
along the way.
514
00:36:58,770 --> 00:37:02,770
People are going to be hearing about it
from hundreds of miles away.
515
00:37:03,050 --> 00:37:08,710
And they're going to come and join in.
So it's going to be a kind of rolling
516
00:37:08,710 --> 00:37:09,710
spectacle.
517
00:37:10,390 --> 00:37:14,770
And their reward looks an awful lot like
what the workers at Stonehenge
518
00:37:14,770 --> 00:37:18,290
received. To do something good. To learn
new skills.
519
00:37:18,990 --> 00:37:20,410
To be part of a team.
520
00:37:20,750 --> 00:37:25,330
And just possibly have a great time
doing it.
521
00:37:25,770 --> 00:37:29,130
No matter how you cut it, there's going
to be a whole lot of lifting.
522
00:37:29,450 --> 00:37:36,170
But rather than move 200 tons of
bluestones from 180 miles away, we'll
523
00:37:36,170 --> 00:37:37,950
concrete trucks do the job.
524
00:37:38,470 --> 00:37:40,270
150 of them, to be exact.
525
00:37:40,690 --> 00:37:46,450
The concrete will be poured into giant
molds off -site and left to dry.
526
00:37:47,190 --> 00:37:53,390
56 of the small ones, if you call 2 to 5
tons small, and 80 of the big ones,
527
00:37:55,450 --> 00:37:56,450
and broken ones.
528
00:37:57,390 --> 00:38:03,010
Once the concrete sets, we'll kick it
old school and use sledges to pull the
529
00:38:03,010 --> 00:38:07,910
stones to our worksite, a labor force of
20 ,000 people.
530
00:38:08,370 --> 00:38:13,610
To lift our concrete forms upright, we
dig massive holes with sloped sides,
531
00:38:13,890 --> 00:38:16,590
lining the holes with angled wooden
stakes.
532
00:38:18,150 --> 00:38:24,550
The stakes, plus A -frames, provide the
leverage it takes for a good old tug -of
533
00:38:24,550 --> 00:38:29,920
-war. As for getting the top stones on
the uprights, there's one theory that
534
00:38:29,920 --> 00:38:32,440
makes more sense than alien builders.
535
00:38:32,780 --> 00:38:35,500
But it's not going to be easy.
536
00:38:35,960 --> 00:38:41,720
You don't do it with a timber structure,
but you build yourself an earthen
537
00:38:41,720 --> 00:38:48,720
mound, a ramp. And you then pull the
lintel up that ramp. And with
538
00:38:48,720 --> 00:38:54,240
the earth, you then just dig it away so
that gradually it lowers itself.
539
00:38:55,070 --> 00:38:58,690
To my mind, that's the simplest way to
do it.
540
00:39:00,090 --> 00:39:06,190
So we need a whole lot of dirt and elbow
grease to build these earthen ramps.
541
00:39:06,570 --> 00:39:11,470
But will we really be able to motivate
our builders to construct one of the
542
00:39:11,470 --> 00:39:17,030
world's most fascinating, yet
logistically challenging structures
543
00:39:17,030 --> 00:39:18,030
machinery?
544
00:39:19,310 --> 00:39:23,450
I think there is a group of people out
there who would say, oh, well, I don't
545
00:39:23,450 --> 00:39:24,670
believe we can do this.
546
00:39:24,990 --> 00:39:26,530
without modern technology.
547
00:39:27,150 --> 00:39:31,490
So I want to see how this is done. They
want to participate for that kind of
548
00:39:31,490 --> 00:39:35,390
knowledge. I think there are other
people who just want to be part of
549
00:39:35,390 --> 00:39:41,130
fun. And to me, trying to lift a 20 -ton
rock doesn't sound very fun, but
550
00:39:41,130 --> 00:39:42,990
there's somebody out there for every
project.
551
00:39:44,450 --> 00:39:45,790
That's good enough for us.
552
00:39:46,710 --> 00:39:53,710
A perfect stone circle aligned in
harmony with the summer and winter
553
00:39:55,400 --> 00:40:01,940
and created in the Alberta Badlands at
the exact latitude of the original. A
554
00:40:01,940 --> 00:40:07,340
year -round venue to celebrate female
power, with excellent acoustics to hold
555
00:40:07,340 --> 00:40:08,860
legendary parties.
556
00:40:09,180 --> 00:40:11,360
But what's all this going to cost?
557
00:40:13,180 --> 00:40:17,520
The social media -driven workforce will
keep the labor cheap.
558
00:40:18,460 --> 00:40:23,060
If I were trying to recruit a thousand
volunteers,
559
00:40:24,310 --> 00:40:29,770
to travel somewhere, to rebuild
Stonehenge. I'd be looking at the
560
00:40:29,770 --> 00:40:34,970
people, the people who have that
interest in learning how it worked, the
561
00:40:34,970 --> 00:40:36,930
archaeologists, the amateur scientists.
562
00:40:38,330 --> 00:40:43,210
We're estimating $100 million, about the
same as it costs to build a small
563
00:40:43,210 --> 00:40:44,210
stadium.
564
00:40:44,570 --> 00:40:48,390
Stonehenge is much simpler, but making
it old school is going to drive up the
565
00:40:48,390 --> 00:40:49,390
bill.
566
00:40:50,210 --> 00:40:52,310
But it would be worth every penny.
567
00:40:53,930 --> 00:40:57,110
Because when humans work together, we're
unstoppable.
568
00:40:58,410 --> 00:41:03,970
Stonehenge is an eternal monument to
that fact, an Old Testament to the best
569
00:41:03,970 --> 00:41:04,970
can be.
570
00:41:05,750 --> 00:41:10,950
There's no denying the incredible power
of the original, but a Stonehenge 2 .0
571
00:41:10,950 --> 00:41:15,150
might be just the sort of project we
could all use these days.
572
00:41:16,590 --> 00:41:21,250
A place to come together with friends
and to revel with strangers.
573
00:41:22,160 --> 00:41:28,780
to celebrate the past and look forward
to a brighter future if we built it
574
00:41:28,780 --> 00:41:29,780
today.
