Stonehenge is one of the greatest mysteries in ancient history.

This would have been the most amazing and ambitious project that anyone could

imagine.

Created 5 ,000 years ago, generations of experts have studied Stonehenge, but

its construction and purpose still remain a mystery.

It's just magical, isn't it? You know, just the simple thing of how did they

build it?

So now we're curious.

Could we recreate this legendary masterpiece with today's technology?

I do think this kind of project would attract a certain type of person.

If I had a thousand people working with me, I don't think I could build

something like that.

Here's the plan.

We're rounding up the best engineers, archaeologists, and logistics experts to

help us build our own iconic monument.

Even more colossal, awe -inspiring, and built to last.

There's an old army expression, actually, that says amateur talk tactics

professionals talk logistics.

Imagine. The world's greatest wonders reimagined.

We're wondering, how long would it take?

How much would it cost?

How many workers would we need?

Could we even do it?

If we built it today.

Situated on Salisbury Plain in southern England, this puzzling ring of stone

slabs has baffled researchers for centuries.

Stonehenge just has that kind of breathtaking,

aspect to it.

It makes the hairs on the back of your neck stand up.

Well, I think everybody tends to find Stonehenge fascinating both because it's

very old and the people that far back in time could build something that's so

incredibly complicated.

So complicated that some theorists have credited its construction to giants,

Merlin the Magician, and even aliens.

Even today, how it was built and why is still under debate.

Archaeologist Michael Parker Pearson and researcher Barney Harris have studied

the mysteries behind Stonehenge's construction extensively.

We see the rise in the sense of prehistoric mysteries and all sorts of

outrageous theories about spacemen and aliens.

constructing civilizations on Earth because humans simply weren't considered

to it.

There's a playfulness to it because it's just these cartoonishly large stones

and this enormous burning question of how was this done and why was this done?

It must have been built for the ancestors because that's what we do with

monuments. Stone is durable and eternal to represent, in fact, to even become

the ancestors.

In terms of its function, some of the beauty of prehistory is just that space,

that lack of evidence to allow creativity.

You know, that's part of the enchantment of it.

So just how did ancient people construct this colossal monument without access

to modern tools?

First things first.

Let's start with what we know.

The site's construction began around 3100 BCE.

and took over a thousand years to complete.

On average, the stones weigh about 25 tons and measure about 30 feet long.

Evidence suggests the prehistoric ruin was built in stages.

The first and oldest part of Stonehenge is a massive circular ditch, or

henge. The actual hinge itself is basically just a big circular trench

dig the soil and rock out. We know that was done using picks made from deer

antlers and shovels made from the shoulder blades of oxen. And we know

because they left those in the bottom of the holes.

Within the ditch was a ring of 56 pits, or holes, dotted around the site's

perimeter, forming a circle 905 feet across.

The exact purpose of the holes remains a mystery.

But some historians believe that they were initially used to support wooden

posts.

For several hundred years, Stonehenge remained largely untouched.

Then, suddenly, around 2500 BC, the blue stones started to arrive.

Nearly 80 blue stones, weighing between two to five tons each, were set up in

two concentric half circles.

But the Neolithic builders were far from finished.

It's when they bring in the big ones.

And those are what we call sarsen stones. It's a kind of cemented

At some point, 30 massive sarsen stones, weighing up to 50 tons, were brought in

and arranged into the famous outer circle.

A horizontal structure known as lintels was then placed on top of the sarsen

stones. Well, at the same time, builders also created what would become known as

the inner circle.

You also have what's called sarsen horseshoe, which is an arrangement of

trilithons arranged in the center of the site, forming roughly a horseshoe.

And then the second major sarsen construction element was the sarsen

Which was a continuous ring of trilithons running all around the

site. That contained 30 uprights and 30 lintels to form, we think, a perfect

ring. So how did all of these giant stones, some weighing up to four tons,

up at Stonehenge?

And who brought them there?

I think part of Stonehenge's appeal is the fact we don't really know for sure

exactly how it was built, why it was built.

To actually move stones that far, you've really got to have decades of

preparation. The ropes, the timbers, it must have been a huge amount of work.

Many modern historians and archaeologists believe that several

of people contributed to Stonehenge, each undertaking a different phase of

construction. New research points to early Europeans originating in Turkey,

and reaching the UK from what is now Portugal.

They were mostly agricultural groups.

They farmed, they had domesticated animals, as they did in a lot of parts

Europe and the Near East and the Middle East at that period in time.

This is actually not much more than 240 generations ago.

They were just like us in the way that they looked and in aspects of how they

lived and acted.

The construction spanned centuries.

And we may never know what drew generations of people to continue

How did that idea stay current and stay important to people over such a long

period of time? That's the real question.

That's difficult to answer.

Probably originally it was just done by passing the knowledge on from one

generation to the next, just in an oral tradition, to explain what they were

actually doing.

So, what would it take to build a modern Stonehenge?

a structure that would last more than 5 ,000 years and continue to inspire awe

for generations.

Could we organize and execute its construction as well as the ancients?

Some say no way.

There comes a point where that very special kind of society just won't work

because the nature of society changed.

But others think a modern Stonehenge is possible.

It's going to take somebody who has a real special interest in the science and

the history of that project.

There's a desire to build something to impress everybody else.

So if you can say I was the one who actually was responsible for that thing

being built, you're going to be a pretty high status person in that society.

Could we assemble a workforce willing to take on this epic challenge?

It's a massive undertaking.

We need some rock -solid reasons to do Stonehenge -style heavy lifting.

If we built it today.

We're imagining how we'd build a new Stonehenge that would leave the famous

in the dust.

But before we work out how we'd build it, we need to figure out why we'd build

it. Yet, that very question.

has stumped archaeologists for centuries.

Stonehenge has a surprising grip on people throughout the world, and even as

archaeologist who studies it, I find that one of the greatest mysteries,

it has just gripped the imagination like no other prehistoric site.

Over the years, archaeologists have attempted to explain why Stonehenge was

built.

One theory... suggests that Stonehenge is a giant astronomical calendar.

For the people that lived there during the time that Stonehenge was

it would have been probably fairly important as a timekeeping mechanism.

People used to mark where the sun rose and set, and because it was critical in

the wintertime to ensure that the summer was going to come back again, they

would watch the rising point of the sun.

As you got towards the solstice around December 21st, typically, the sun would

slow down, slow down, slow down, stop, rise to the same point for a couple of

days, and then start moving back towards the north, ensuring it was actually

going to come back.

You can use it with reasonable certainty to predict some types of eclipses,

especially lunar eclipses.

Others have speculated Stonehenge was built as a gathering place to celebrate

peace and unity.

It's about the spirit of the place, which has something unique about it that

prehistoric people recognized, that that was what drew them to this as being

somewhere special, because it had this remarkable alignment of the heavens and

the earth. If you like, they might have seen this as some kind of cosmic harmony

in this very special place.

What Stonehenge was, and is to this day, is a crowd magnet.

a place built by people for people to come together.

This wasn't just a local monument for local people, but something that was

attracting huge numbers from many different parts of the island. You meet

marriage partners, you form alliances, you resolve conflicts.

Even today, one of the most exciting things about Stonehenge is the mystery

surrounding it.

However... A discovery made in the early 20th century led experts to their most

conclusive explanation yet.

There are definitely cremated human remains that were found in the bottoms

the post holes, dating from some of the earlier periods of time.

Excavations revealed the cremated remains of up to 58 people, providing

that this might actually be an ancient burial site.

and maybe in a symbolic place where people would sort of come together

it was the one structure that they had all sort of contributed towards

much in the same way that even today we do that sort of thing.

Given the connection with death at Stonehenge, it was tempting to think

of the motivating factors for people was the memory of an individual or perhaps

what that individual came to symbolise in a wider sense.

Further analysis of the remains.

exposed an astounding piece of evidence.

The majority are women. It's very possible that we are seeing a complete

in the gender politics of that society.

So we have the very interesting possibility that Stonehenge was actually

masterminded by women.

Clearly, Stonehenge may have served several purposes, and no theory stands

as more valid than the other.

Whether its purpose was to keep track of time, celebrate community, or represent

female empowerment.

Put together, that's more than enough reason to build a new Stonehenge.

So, let's do it.

And since we want to do this right, we'll need a sacred space and use

designs and methods.

will also match the human strength required to carry massive stones

miles. And that mission will guide every decision we make on our modern -day

Stonehenge. But before we can imagine recreating Stonehenge, we need to decide

where we build it.

If Stonehenge is a calendar most famously known for its alignment with

winter and summer solstice, If our Stonehenge is going to do the same

timekeeping job, it needs to be built at 51 .789 degrees north.

If you go east of England, that takes you sort of through the Netherlands,

Germany, Poland, through Russia, just north of Mongolia, the very extreme

northern part of China, and a little bit down towards Vladivostok in Russia.

So what are our options?

You could build one in the southern hemisphere.

If you go to the same latitude south of the equator, the only place where

there's actually any land is the very southern part of Patagonia.

Chile, southern Chile, or southern Argentina.

There's another place in the northern hemisphere that could work.

It's about 60 miles north of Calgary, Alberta, in the heart of what's called

Badlands.

It's a remote...

Dramatic backdrop for a modern -day Stonehenge. From the architecture, we're

starting to get the idea that this is perhaps an exclusive space, symbolically

and physically separated from the rest of the landscape.

The Badlands are on the exact latitude of Stonehenge and perfect for our modern

-day eternal stone monument.

We're sold, but we're not ready to get rolling just yet.

We've still got to find our workers.

I do think this kind of project would attract a certain type of person.

And figure out how they moved all that rock without alien intervention.

It's just magical, isn't it? You know, just the simple thing of how did they

build it? And what materials would we need to recreate the stone circle?

We're talking really accurate construction techniques here. It's

us today to imagine.

that level of precision being achieved.

Luckily, we know a few experts that can lead us in the right direction.

If we built it today.

We're imagining how we'd build Stonehenge today.

We know we'd want to replicate the design, and we'd like to build it north

Calgary, Alberta's dark badlands.

So that leads to our next question.

What materials would we use for our modern -day Stonehenge?

Would we extract sandstone and spot a dolerite from a quarry?

Or would we use a different kind of material?

Because for astronomy purposes, it could really be built out of anything.

The main thing is the actual positioning of the things and having them at the

right latitude. So, yes, you could make it out of anything, including paper

mache.

Before we decide, we want to know where the stones that make up Stonehenge came

from.

For many years, archaeologists believed that the Tharsen stones were brought

from a region 20 miles away.

Yet, recent research has pinpointed the specific area.

We've just found out that they come from 15 miles to the north.

They just wanted stone of a suitable size and shape, and the

nearest they could find it was where they got it from.

Unlike the sarsen stones, the bluestones presented their own mystery, because

there isn't any naturally occurring bluestone nearby.

However... Geological studies suggest a potential source far to the west of

Stonehenge, in Wales.

What we've discovered is actually where the vast majority of the Welsh stones

come from is the Preseli Hill.

Amazingly, these quarries in Wales are nearly 175 miles away from

Stonehenge. Even more amazingly...

Recent excavations suggest that some of the blue stones may have initially been

part of a stone circle at Wan Mon in the Purcelli Hills.

It was here that we were able to excavate two of the quarries supplying

stones and we found the remains of a dismantled stone circle.

A stone circle that we have now dated and which we know was put up

Before Stonehenge.

So now we're curious.

Is there an easier way to build a modern -day Stonehenge that doesn't involve

dragging all that stone?

A modern version of Stonehenge, although making it out of rock would be quite

impressive, I suspect if anybody actually did that, they would just use

concrete. Because we're really good at working with concrete. You can just make

a form to whatever shape you want.

Concrete it is.

We'd model Stonehenge in a computer and use giant molds to shape the concrete

for each individual stone.

3D printed concrete is also an option, the latest technique that's

revolutionizing construction these days.

But we still have to figure out how and who is going to build this monument.

This brings us back to what Stonehenge might have been used for.

Some archaeologists suggest that Stonehenge was a gathering place.

So, what if we turned our Stonehenge 2 .0 into an outdoor concert venue?

How would our materials hold up?

If we think of any ritual that we get involved in, a wedding or a funeral or a

christening, whatever it might be, it involves sound.

So understanding what the sound was like in the past and how the stones might

have affected that sound is really important to understand the use of the

Setting up an acoustics test on Salisbury Plain isn't in the cards.

So, acoustics engineer Trevor Cox created a digital Stonehenge replica.

If you were to go and measure Stonehenge today, you'd get a very different

acoustic response because so many of the stones are missing or on the floor.

I draw on archaeology, so I talked to, in this case, Historic England, who

actually had a computer model where they had all the stones in their original

configurations.

Next, Trevor brought those computer models to life with a 3D printer and

them out in a soundproof chamber.

It's vital that the stones are placed at the right size, right shape, and placed

in exactly the right place, because we're working at 1 to 12 scale, so

everything's shrunk by 12, so we've got to get it into millimetre accuracy.

So this test chamber has absorbent walls, and that means any sound that

the stone circle disappears and gets absorbed by the walls. And that's like

real Stonehenge.

And the results were truly extraordinary.

I think the first surprise in what you find in Stonehenge is it's got

reverberation.

The sound does linger a little while before dying away. The reverberation

which is what we measure, is about 0 .6, 0 .7 seconds.

Remarkably, that reverberation time...

is about the same as many of the world's finest concert halls.

It's half as good as the gold standard, New York's famed Carnegie Hall.

So the acoustic supports the fact that this is a site where ceremonies could

take place.

What you learn from the acoustic study is it tells you maybe a bit about the

of the space.

The fact that speech communication is easier within the circle, the fact that

music sounds better within the circle, implies that anyone who was involved in

the ceremony who was within that circle was getting a pretty sound.

And Trevor says 3D printing in concrete is a perfect way to construct a great

-sounding outdoor theater.

He's already done it in miniature.

If we actually print hollows, you then have to backfill them with concrete,

because from the acoustic perspective, we're trying to mimic stone here, so we

want it to be heavy and impervious, so we actually fill the back of them up

concrete.

If Stonehenge is really an old amplifier, it's centuries ahead of its

People care about sound volume when they need to communicate.

And, as in any megalogistical project, Communication is everything.

So now we're ready to build it in sight and sound.

But we still need to figure out how to get 3 ,000 tons of concrete to the

Alberta Badlands.

How do you move stones? Even if you've got wooden sledges and thousands of

willing helpers, it's a massive undertaking.

And to somehow raise it to the sky in a perfect circle.

This would have been the most amazing and ambitious project that anyone could

imagine. Can our team conquer the seemingly impossible?

If we build it today.

We're exploring the secrets behind the world's greatest prehistoric monument,

Stonehenge, to find out how we'd build it today.

Of course, there's no denying the original stands as an enduring testament

the engineering skills of the Neolithic people who created it nearly 5 ,000

years ago.

But, as it turns out, we're far from being the first to take on this

There have been people who have replicated Stonehenge from various

There's actually a refrigerator henge where there's sort of a replica made of

old dead refrigerators. There's ones made out of old junk cars.

Nigel Allen constructed his backyard stone circle in Nova Scotia, Canada.

This location was just in the field and it was a perfectly flat circular space

in the midst of rolling terrain going down to the river. But this was a flat

dime begging to have a circle stone put around its perimeter.

With a local quarry not far away, He struck a deal to buy some big stones and

broke ground.

So I said, I've got an idea.

So I marked a circle off, a radius with a rope and done the circle, figured out

where I wanted to put the stones, dug holes for the stones, had them load them

in one of their giant dump trucks, and they would spin one at a time, dump it

directly in front of the hole, and I'd have one of the larger excavators come,

and he would... Just grab the end of it and tip it up.

Nigel's stones weigh between 6 and 12 tons, half the size of the towering

monsters at Stonehenge.

And even they took a 15 -ton crane and a massive excavator to do the job,

machinery the folks who built Stonehenge didn't have.

The texture of the rock makes it look ancient.

The way it's rippled and weathered makes it look like it's been here thousands

of years.

Two decades after building it, Nigel Stonehenge has given locals in his quiet

community something to talk about.

There was a little reaction when the stones went up so quickly. People were

used to things changing out in the middle of nowhere, so they were a little

apprehensive, and it brought lots of different types of people in.

And it's given him an appreciation for the skills of the ancient builders.

Having done this and having come in close contact with these huge objects,

quite convinced that the people who have come before were more resourceful,

stronger, smarter, and had a better idea how to do things.

5 ,000 years ago, the ancient people moved all that rock.

But we still don't know how it got from point A to point B without modern

equipment.

Historians used to think Stonehenge's builders engineered some kind of log

rolling system.

So this notion has been persistently explored by archaeologists, testing

these rollers do really work the way they're proposed.

But when you look at the evidence, what you find is that this idea doesn't

really hold water.

From a technical perspective, it's difficult, because when you have

rollers... You look on the ground around us, the ground is uneven, there's

bumps, there's lumps.

This is going to set these rollers all different directions. They're going to

jamming into each other, moving across each other.

Any kind of hill, it's difficult to negotiate it.

So really, the rollers' idea should be confined, I think, to the dustbin of

history.

So if we don't use log rollers...

How are we going to move 3 ,000 tonnes of concrete?

A much more viable method, and certainly one that we see represented as well

ethnographically, is the idea that stones were placed on sledges and then,

necessary, some kind of trackway was prepared for these sledges. Bits of

bits of brush, bits of anything really to just keep the sledge from biting into

the ground and just pulled along in that way.

To put the debate to bed once and for all, researcher Barney Harris and his

colleagues from the University College London tested alternative ways of moving

large stones without rollers.

And we explored two things. One was the particular form of sledge that we see

used in ethnographic accounts.

And then the second thing we wanted to investigate was the kind of tracking

was needed to move this sledge.

And we were interested in the idea of a timber slipway.

We started off with 30 or 40 students pulling this sledge with the stone

strapped to it, and that went well.

And then towards the end, they managed to sort of fine -tune it so there was

about eight students managing to pull this sledge with the stone on.

The sledge simply slides across the top of it, and this is a much more stable

arrangement than log rollers, but does still help reduce the friction.

The sledge method it is.

Now we can cross location, materials, and equipment off our to -do list, but

biggest challenge may lie ahead.

How many people will we need to hire?

Well, I think you would have a hard time finding hundreds or thousands of...

people, you would need to move a 20 -ton rock day after day after day.

How many people out there are going to have the stamina and the strength to

actually be able to do that?

I suspect it may be a combination where some people were actually paid and other

people just volunteered.

My guess is that you actually have separate, probably geographically

teams who are responsible for one part of the circle.

and that collectively they do this together.

We'll need an army and the right general to lead it. Luckily, we have one of the

world's best in mind.

If we built it today.

We're imagining how we'd build a modern -day Stonehenge.

So far.

we figured out that we'd want to build it north of Calgary, in Alberta's stark

Badlands.

We'd need to 3D print molds for 157 stones made of concrete, weighing

over 3 ,000 tons.

And to move all that heavy rock, we'll employ a sledge system that reduces

friction on the stone, allowing it to move easier and faster.

Experts estimate that it took nearly 10 million combined hours of labor to build

the original Stonehenge. And that was over 5 ,000 years.

Today, thanks to technology, we're hoping to cut that time down

Which leads us to our next challenge.

How many workers would we need?

And where are we going to find them?

The engineering of the project is the easy part. No plumbing, no heat, no

electrics, no building inspectors.

With 157 stones, let's say 25 workers per stone, for a total of 3

,925 hands, and round up to 4 ,000.

Multiply by 5 for complex jobs like our modern Stonehenge, that's 20 ,000 people

in total.

Not impossible, but how do you keep them around long enough to get the job done?

If you're out on an operation, you're going to need probably three to four

supporters for every one operator on the front line.

Caleb McDonald is a logistics manager with the Canadian Armed Forces.

He plans massive operations for a living.

What we'd usually do is send in a sort of a skeleton crew on the front end,

which might be labor heavy, and they have to sort of establish the groundwork

for the rest of the technicians and the soldiers to come in on the back end.

And so what you'd see is laborers and a few electricians, cooks, build out the

accommodations area, set up power generation and power distribution.

So when the actual workforce arrives, they have somewhere to live, they have

something to eat, they have water to drink, and they can go through all of

functions they need to do in order to get the work done.

What kind of supplies would our mobile workforce need?

From a caloric perspective, we start with 3 ,000 or 4 ,000 for manual labor.

That's probably 150 to 200 loaves of bread per day. And you do the same thing

for fresh fruit. And you do the same thing for meat and all those other

commodities that you need soldiers to be healthy and productive.

Water being probably the most critical of all the sort of commodities that we

use to keep a camp running.

Shelter, food and water for thousands of people for a thousand years.

We're on our way to assembling an epic workforce backed by a top notch

team.

The challenges are simply motivating that number of people to stay on task

so long.

And just like today, the pitch needs to pack a punch.

Recruiting is its own science, and part of it is around selling what the

adventure is.

Because if we just said, yeah, your job is going to be to dig holes for eight

hours a day, come on out, we're hiring, then we're not going to get anybody

coming in.

Social media expert Anita Kirkbride thinks finding people would be easy.

Organizing Stonehenge 2 .0 would be the Internet event of the century.

Well, with the click of a button on...

pretty much every social network right now, you could potentially connect with

billions of people. To get people to want to be a part of a big project like

this, it's...

Showing them how they can be part of a community.

The days of gathering a workforce through unions, churches, and clubs are

Anita thinks the time has never been better to raise a social media -driven

force. This kind of project would attract a certain type of person,

wants to see how things were done, the people who are curious about how did

people actually move these 20 -ton rocks.

And for some people, they won't believe that people actually were able to do

that until they participate in it.

I could see the construction of something like Stonehenge, the movement

stones taking place on an annual basis, with people coming together each year to

move another stone and perhaps bundling it in with a massive party.

When the job goes viral, influencers will line up.

You could be doing live updates.

to share what's happening.

You could be showing the live footage of people moving these 20 -ton rocks.

Pretty much all of the social media now have live streaming capabilities.

You could have a really good group of people helping you publicize this where

they've got 2 million followers.

So how long would this project take with a first -class logistics team and an

army of influencers?

You can move maybe three miles a day. For 180 miles, you could do that in a

summer season.

Cutting back on the thousand years it took to build Stonehenge.

No problem.

It's going to have been done in less than 10 years. That would be my guess.

10 years isn't much worse than any other modern mega build.

So let's form our team and leave the Stonehenge builders in the dust.

But there's one burning question.

Who's picking up the bill if we built it today?

We're rebuilding Stonehenge, reimagining 3 ,000 tons of stone

in an outdoor venue built for thousands of people, celebrating the power of

women with a monument that will last an eternity.

And thanks to non -profit organizations,

Construction volunteering is thriving.

Over 13 million people have volunteered their time to help build for people in

need in the past half century.

It's an extraordinary undertaking.

It's going to be more than merely, let's start at A and go to B.

Because you're going to have people all along the way.

People are going to be hearing about it from hundreds of miles away.

And they're going to come and join in. So it's going to be a kind of rolling

spectacle.

And their reward looks an awful lot like what the workers at Stonehenge

received. To do something good. To learn new skills.

To be part of a team.

And just possibly have a great time doing it.

No matter how you cut it, there's going to be a whole lot of lifting.

But rather than move 200 tons of bluestones from 180 miles away, we'll

concrete trucks do the job.

150 of them, to be exact.

The concrete will be poured into giant molds off -site and left to dry.

56 of the small ones, if you call 2 to 5 tons small, and 80 of the big ones,

and broken ones.

Once the concrete sets, we'll kick it old school and use sledges to pull the

stones to our worksite, a labor force of 20 ,000 people.

To lift our concrete forms upright, we dig massive holes with sloped sides,

lining the holes with angled wooden stakes.

The stakes, plus A -frames, provide the leverage it takes for a good old tug -of

-war. As for getting the top stones on the uprights, there's one theory that

makes more sense than alien builders.

But it's not going to be easy.

You don't do it with a timber structure, but you build yourself an earthen

mound, a ramp. And you then pull the lintel up that ramp. And with

the earth, you then just dig it away so that gradually it lowers itself.

To my mind, that's the simplest way to do it.

So we need a whole lot of dirt and elbow grease to build these earthen ramps.

But will we really be able to motivate our builders to construct one of the

world's most fascinating, yet logistically challenging structures

machinery?

I think there is a group of people out there who would say, oh, well, I don't

believe we can do this.

without modern technology.

So I want to see how this is done. They want to participate for that kind of

knowledge. I think there are other people who just want to be part of

fun. And to me, trying to lift a 20 -ton rock doesn't sound very fun, but

there's somebody out there for every project.

That's good enough for us.

A perfect stone circle aligned in harmony with the summer and winter

and created in the Alberta Badlands at the exact latitude of the original. A

year -round venue to celebrate female power, with excellent acoustics to hold

legendary parties.

But what's all this going to cost?

The social media -driven workforce will keep the labor cheap.

If I were trying to recruit a thousand volunteers,

to travel somewhere, to rebuild Stonehenge. I'd be looking at the

people, the people who have that interest in learning how it worked, the

archaeologists, the amateur scientists.

We're estimating $100 million, about the same as it costs to build a small

stadium.

Stonehenge is much simpler, but making it old school is going to drive up the

bill.

But it would be worth every penny.

Because when humans work together, we're unstoppable.

Stonehenge is an eternal monument to that fact, an Old Testament to the best

can be.

There's no denying the incredible power of the original, but a Stonehenge 2 .0

might be just the sort of project we could all use these days.

A place to come together with friends and to revel with strangers.

to celebrate the past and look forward to a brighter future if we built it

today.
