A sprawling, ancient city

located entirely underground.

A giant, stone tomb built to be a gateway

to the afterlife.

And 11 enormous churches that were carved

out of solid rock.

Throughout the world, there are ancient structures

that seem to defy explanation.

Monuments so massive

and so intricately constructed

that even with today's technology,

they would be nearly impossible to duplicate.

How were ancient civilizations able

to build such extraordinary structures?

And perhaps more importantly,

what purpose did they serve?

Well, that is what we'll try and find out.

High in the mountains of northern Ethiopia,

a mile and a half above sea level,

lies the city of Lalibela.

Each year, tens of thousands of worshippers

make the arduous journey here,

despite its remote location,

to visit 11 of the strangest

holy places on Earth.

Lalibela is one of Africa's

most mysterious sites.

It's a complex of 11 monolithic churches that are

hewn right out of the bedrock.

Most churches are built on the surface,

and they're built from the bottom up.

Whereas in Lalibela, they're built from the top down.

It's the only place on the Earth that has cathedrals that are

built underground as opposed to being built on the surface.

What makes the Lalibela churches so unique

is not just their building construction,

which is unlike anything else in the world,

but also the otherworldly feel of the complexes

where these different monuments can be found.

Entering into the complex of churches

was almost like entering another realm.

Almost as if those who constructed Lalibela

had a ritual function,

and that was to bring themselves closer to God.

It's an incredible piece of engineering,

this idea that you build 11 churches below ground,

but it creates its own unique problems.

How do people get down there?

How did they move all of the rock out and where did it go?

Those are the things that start running through my mind.

Dating back to the 12th century A.D.,

each of Lalibela's 11 churches

was painstakingly carved by hand,

and from the outside, like enormous sculptures.

The complex also includes an extensive system of tunnels

and catacombs, all carved out of solid bedrock.

But why?

Why build a magnificent series of structures

in the toughest way possible?

The builder of Lalibela was a king

by this very name, Lalibela.

And it is said that, in the 12th century,

he was living in Jerusalem, and decided to come back

into Ethiopia and create

these monolithic churches.

And it's very clear that Lalibela,

in the design of these different churches,

was trying to replicate Jerusalem.

Indeed, he was trying to create a new Jerusalem.

So, by entering into this complex, it's almost like

you were entering into Jerusalem itself,

which was considered to be the most

holy shrine in the world.

It is described that Lalibela had a dream.

And in the dream he was instructed by God to go back and

make a copy of Jerusalem at the site.

And, in order to fulfill God's request,

King Lalibela and others who were involved

worked night and day for 20 years.

So, in their minds, right at the beginning,

they had a three-dimensional structure in mind.

Because, when they started, it was just a big piece of rock.

And how did they know that, if they were going to go

150 feet down into the ground,

that everything was okay?

Because the worst possible thing

would be that you'd almost finished, and then

you found that there was a massive problem at the bottom.

11 underground churches,

some over 100 feet deep,

each carved from a single block

of stone in only 20 years' time?

Archaeologists date the churches back nearly a thousand years.

But even with today's modern technology,

such an incredible architectural feat

would be considered impossible.

So, how was it accomplished?

If we go and build a big structure today, a skyscraper,

we have blueprints, we have engineering,

design pathways, and we have a construction plan.

It tells us how we will do every step of the way,

where every screw, nut, bolt, weld, poured concrete goes.

None of that exists for these large, ancient structures.

So, we really got to think outside the box

and try to find how they were done,

why they were done, and who built them.

A very curious thing at Lalibela is that there are some

very unique carvings there, some very interesting symbols

that are carved into these churches.

Do they mean something if you put them together?

In the church of St. Mary at Lalibela,

there is the Star of David,

and this, along with a number of other mementos

and designs, are extremely indicative

of the presence of the Knights Templar.

This has suggested to many

that they may well have been present

during the construction

of the churches at Lalibela.

Now, the Knights Templar were a very interesting

religious order that became very powerful

during the Middle Ages,

but what people don't often realize is

they were very interested in building,

in, geometry,

in, numerology,

and so, they're at once very practical

and pragmatic, and on the other hand,

also very spiritual and mystic.

The Knights Templar had

a great amount of knowledge in masonry

and architecture and building structures.

Now, it's debated as to whether or not the Knights Templar

would have been in Ethiopia at this time.

But there's some interesting evidence that

an Armenian geographer at the time

documented seeing men with red and white regalia,

blonde or reddish hair, long hair,

which could indicate that he's talking about Templars.

So, it could be that the Templars themselves

were the ones that built Lalibela

or that they helped King Lalibela build the site.

Could Templar stone masons have influenced

the construction of the churches at Lalibela?

And if so, for what purpose?

If you look around Lalibela, there are altars there

that have spaces in them that would

precisely fit the Ark of the Covenant,

which was approximately four feet in length,

two feet wide, and around two feet in height.

It has been suggested that the rock-cut churches

at Lalibela were built to house the Ark of the Covenant.

The lost Ark of the Covenant...

The gold box which contained the original Ten Commandments...

Could it have been hidden at Lalibela centuries ago?

During the Crusades, we know that the Templars

occupied the Temple of Solomon.

And so, it could be that they were

the keepers of the Ark of the Covenant.

And the more you look at Lalibela and given the fact

that we see that it's built underground,

you start to think, here we have these churches

that are hewn out of these megalithic rocks.

They're built like defensive structures.

They have all kinds of interesting

symbolism there that indicate Templars.

And you start getting the impression that this is

actually some kind of defensive fortress to protect something.

Was Lalibela originally built to house and hide

the Ark of the Covenant?

Well, if that's true, then it would certainly

explain why the churches resemble fortresses.

There's another ancient structure, located in Turkey,

that may also have a connection to the divine.

It's an ancient temple that some believe was built on the site

of the Garden of Eden.

While plowing his field, shepherd Safak Yildiz spots

a strangely-shaped stone emerging from the parched earth.

When he brushes away the dirt, he realizes the stone

may be part of a much larger object.

After reporting his find,

he is visited by archaeologist Klaus Schmidt

and a team from the German Archaeological Institute.

Further excavation reveals the stone is actually part

of a massive, elaborately carved

stone pillar, one

in what turns out to be dozens

that form an ancient underground complex.

Göbekli Tepe is arguably the most important

archaeological discovery in recent years.

We're talking about a whole series

of stone circles

built on the top of a mountain.

If you can imagine Stonehenge in England,

but multiply it by 20 times

and have these stones in circles

facing towards two massive, great monoliths,

as much as 18 and a half feet tall,

weighing between 15 and 20 tons,

this is what we see at Göbekli Tepe.

Göbekli Tepe could very well be the first lost civilization.

We've only uncovered a small percentage

of it, like ten or 15%.

We have no idea, really, how much bigger this is

and what else we're gonna find there.

We have to ask ourselves, "Could Göbekli Tepe

been a place of commerce and trade?"

And I think the answer is an undoubted yes

because its construction would have necessitated

the presence of not just hundreds,

but many thousands of people

coming from across the region who,

at the beginning, were hunter-gatherers.

While there are many theories,

the true purpose of Göbekli Tepe remains shrouded in mystery.

But no less mysterious than the stones themselves

is the lost civilization that fashioned them.

Because when sediment layers of the site

were carbon dated, it was shockingly revealed

that Göbekli Tepe is more than 12,000 years old.

Göbekli Tepe really did send shockwaves

through the whole world of early pre-history

because we'd never before known or imagined, even,

that simple hunter-gatherers

could produce such spectacular monumental

structures as are found at Göbekli Tepe.

Now, many of these pillars also have remarkable carvings

on them, wonderful carvings

and bas-reliefs of animals,

birds, insects, all kinds of things.

So, to fashion those and carve them and set them up in these

structures was just absolutely amazing.

More than one-third of Göbekli Tepe's stone pillars

contain elaborate bas-relief carvings of various animals.

But what has many archaeologists and historians puzzled

is that many of the species depicted... like geese

and armadillos and wild boar...

Are not indigenous to the area.

That location just happens to be near where

Noah and the animals and the ark

ended the long journey through the flood.

And these giant pillars in Göbekli Tepe

have carvings of animals, many different kinds of animals.

Are these the animals from the ark?

Did the stories about those animals

end up being depicted in stone?

Could there really be a connection

between Göbekli Tepe and the great flood?

Perhaps.

But according to another audacious theory,

the animal carvings at Göbekli Tepe may have been

inspired by another, even older, Biblical story.

Göbekli Tepe is located in the very area

that the Bible tells us the Garden of Eden was located.

It is said that Eden was where the four rivers

of paradise took their rise.

Two of those rivers were the Euphrates

and the Tigris that flowed through Mesopotamia.

And these both rose in the same area as Göbekli Tepe.

Professor Klaus Schmidt, the German archeologist,

even suggested himself

that this could be the area of Eden

and the point of foundation of civilization.

The Garden of Eden?

It's a fascinating theory,

but one that is not without its problems.

Because archeological evidence shows that Göbekli Tepe

was not only later abandoned,

but also backfilled and deliberately buried.

Why would anyone want to leave and bury

paradise?

Around 8,000 B.C.,

the people of Göbekli Tepe just vanish.

They just disappear.

So, we have to ask ourself, where did they go?

Did they just vanish into oblivion?

What we know is that, recently, archeologists discovered

a number of human skulls that had been modified.

And what this means is that they had been sculpted

or that they had been pierced,

so that they could be hung up,

perhaps on some kind of frame or platform.

They found skulls that are smashed in,

they've found remains that look as if there's been

some kind of mass ritual or murder or sacrifice going on.

There may have actually been a skull cult there.

Do we know what these people were doing? Of course not

because they were doing this thousands

of years before writing took place.

We can try and guess.

We-we know important rituals took place there.

Klaus Schmidt would talk about this as Eden.

I think what he meant was this is an Edenic society because

if you look at the story of the Garden of Eden in the Bible,

that's a hunter-gatherer society,

that's before we discover agriculture.

And so, the fact that here's this place, Göbekli Tepe,

it's really challenging our understandings

of our own origins, our own religious origins.

And you start thinking about what else we're gonna find.

It remains to be seen what will be found

in the rest of the site.

But certainly, I'm sure Göbekli Tepe

has plenty more surprises for us.

Every new enclosure excavated, every new piece of evidence

puts another piece in the jigsaw,

but also at the same time raises new questions

that we find very difficult to answer.

Whether or not Göbekli Tepe has a connection to stories

from the Bible, one thing appears to be certain:

it was built for a profound purpose.

Which is also the case with another massive stone structure.

One that can be found in the Irish countryside,

and may have served as a bridge between the living

and the dead.

Rising above this region's lush fields,

not far from the banks of the River Boyne,

is one of the most mysterious ancient tombs in the world.

Newgrange.

This massive stone structure

has a diameter of 87 yards,

or nearly the size of a football field.

Newgrange is the envy of monuments all around the planet.

The thing that people say when they come here is

they're surprised how big it is.

It is huge. It takes up over an acre

of ground, and there is an estimated

200,000 tons of stone in the monument.

According to archaeological findings,

Newgrange was built around the year 3200 BC,

making it centuries older than both Stonehenge

and the Great Pyramid in Egypt.

Because Newgrange is so ancient,

there's still much that we don't know about the people

who built this extraordinary tomb.

Probably one of the most fascinating

things about Newgrange is the fact that it was built

in pre-metal days,

just as the Stone Age was kind of sort of coming to a close.

And it's difficult to imagine how ancient people were able to

assemble this massive monument, but they managed to do so.

A lot of work went into the building of this monument,

and it was all done with extreme precision.

Inside, there are carved stones.

And then you come into a chamber, which is quite roomy.

So, you have this cathedral-like feeling when you walk inside.

Newgrange is what archaeologists refer to as a passage tomb.

It has a passage leading into the interior.

And in that interior, human bones have generally

been found, in different quantities.

There are human remains in these places,

but the most common, um, burial practice

around this time was cremation.

So, we find most people would be cremated and then interred.

In the traditional Irish folklore

that dates way, way back,

the other world of the dead...

It sort of overlapped with our own.

So, the idea is that these sites would sort of allow

for this passage between the realm of the dead

and the realm of the living.

On the back recess of the inner chamber there is a tri-spiral.

The most common interpretation that people

come up with is that it represents

this constant cycle of renewal and regeneration.

On a spiritual level, it may promise rebirth

for the spirits of the dead.

The tri-spiral is unique to Newgrange.

And it's also found on the entrance stone

and throughout the tomb.

Archeologists who have studied Newgrange

have theorized that this ancient tomb

was intended to serve a profound and mystical purpose.

And as evidence, they point to a curious element of its design

that is visible only one day a year.

Newgrange is unusual in that it has

a very special aperture,

or opening, above the entrance.

On the day of winter solstice,

this glimmering golden beam of sunlight enters there

and pierces the darkness.

When the sun rises at winter solstice,

the light hits the chamber

for precisely 17 minutes.

And some even speculate that the spirits

would have used the light to leave the burial chamber

and go and join the deities.

Did the builders of Newgrange specifically

design it to be a gateway into the afterlife?

Some archaeologists believe that the answer is yes.

And they also claim that Newgrange was built

to allow those who stood within its inner chamber

to communicate directly with the dead.

In the case of Newgrange,

the notion of the sunbeam drawing out

the souls of the deceased and-and leading them

to that other world, is not just a one-way ticket.

It was a portal between worlds.

Were the people inside there... The priests,

for instance, the druids... Were they in contact

with the ancestors who'd gone before?

The builders of the monument

have created a space which is separate,

which is a world for the dead.

There is always a feeling that this is a house for the spirits.

Where consulting with the ancestors,

asking advice from the ancestors,

would have happened 5,000 years ago,

which is extraordinary.

Was Newgrange constructed to be not only a tomb

but also a place where the living

communicated with the dead?

It's an intriguing theory,

which is why archaeologists continue to study Newgrange

in the hope of one day unraveling all of its mysteries.

How people choose to handle their remains

always tells you a lot about what people

think about the afterlife.

Where are they going?

What is the relationship between the soul and the body?

And in Newgrange, this had a lot to do

with this notion that the dead are still around

and perhaps can see you even if you can't see them.

So, in a sense, with Newgrange,

we might even say that the dead did achieve immortality.

The theory that Newgrange was built to be not just a tomb

but also a gateway

between our world and the afterlife

suggests that some ancient structures may have served

a higher purpose than we might have once believed.

In fact, there's a vast underground city

that was constructed more than 2,000 years ago

that some believe was designed to ensure

the survival of the human race.

Bordered by the Black Sea to the north

and by the Taurus Mountains to the south

lies the craggy regions of Cappadocia.

Here, wind, water, and time

have sculpted the volcanic rocks into bizarre

and almost surreal shapes.

But, believe it or not, the most unusual thing

that was ever discovered in this otherworldly landscape

was found not above ground but far below.

In 1963, during a simple home renovation

in the town of Derinkuyu,

a cave wall was punctured, revealing a passageway

to what appeared to be an intricate underground city

thousands of years old and more than 280 feet deep.

Derinkuyu is a pretty amazing story 'cause,

just imagine that you're working in your basement one day,

you knock a hole in the wall,

and what you find is a-a city that is sort of the size

of a-a really large castle, but it's actually underground,

and it was done in a time before there was

really any mechanical means to provide

water or ventilation or any of those things.

The only thing on the surface that you can see

are what appear to be wells.

As you approach Derinkuyu,

you would certainly not be aware

that you were walking over

the position of an underground city.

It would have been the home for thousands of people at a time

at some point in the distant past.

Experts believe that Derinkuyu housed an estimated

20,000 men, women, and children, and included

religious centers, storerooms, and living rooms.

Many archaeologists and scholars propose that Derinkuyu

was most likely built around 800 B.C. by the Phrygians,

a Bronze Age people related to the Trojans,

and was intended to serve as a temporary shelter from invasion.

But others believe it was built by the Hittites,

a warrior people mentioned in the Bible

who flourished a few hundred years before that.

It's in a place that's had multiple wars.

There's conflict taking place all the time.

And when you're above ground, people can see you for miles.

You know, each night, you're lighting fires

to get some light inside the space.

And so that can be seen from 20 miles or more.

Once they go below ground, they're invisible.

It has massive stones that can be lowered to block

passageways that human beings can only go through

in single file, making it very easy to defend.

There are also rumors that it is connected by a vast

tunnel system going many, many kilometers to other

underground cities in the neighborhood.

So, it had emergency escape routes.

So, the whole thing was a quite remarkable

subterranean fortress.

While there is evidence to suggest

that several different cultures have used Derinkuyu

as a fortified sanctuary,

in the centuries that have passed since its initial

construction, some researchers

have theorized that it is much, much older

than mainstream archaeologists think.

And that its original architects had an even bigger threat

in mind when they built it.

The curator of Derinkuyu in Cappadocia,

Ömer Demir, had found the evidence

suggesting that each of the different stories

or levels would seem to have been constructed

by different cultures at different times.

And what he found was incredible.

For he discovered that there were tools,

stone tools, here, that dated back to paleolithic times.

The implications of this are enormous

because what this suggests is that

Derinkuyu goes back at least 12,000 years

and was present at the end of the last ice age

and may well have been

a place where our ancestors sought refuge

at the time of a cataclysm,

a cataclysm that may well have devastated

large parts of the Earth

at the very end of the paleolithic era.

A cataclysm?

Could it be that the original inhabitants of Derinkuyu

built it as a shelter to protect them

during the Earth's last great ice age?

A time when the Earth's climate was estimated to be more than

ten degrees colder than it is now?

So cold that hardly anything could

grow or even survive above ground.

When you build your city underground,

you get two major off-the-top advantages,

one sort of environmental.

You're gonna have great thermal properties.

It's gonna be cool when you need it to be cool,

but it won't get too cold, so it'll be kind of warm enough

when you need it to be warm.

Thinking about when this was built and inhabited

really remains this exciting, mysterious, open question.

Even this idea of other cities underground,

like, how common was that for humans to build their homes

underground versus on the surface of the ground?

It does feel like we've just really

scratched the surface of what could be below us.

There could be much more. There could be many more

of these cave systems in Turkey.

So, there's mystery still to be found

deep within the Earth.

The truth is we may never know for sure why

or even how these ancient underground cities were built.

And that's especially true in the case of Derinkuyu,

because the secrets of its construction techniques

seem to have disappeared

along with whoever built it.

Even today, with all of the modern technology

that we have, it would be incredibly complicated and

a massive undertaking to do something like that.

And sometimes we look at these ancient marvels

and we try and figure out could we build that today

to that level of accuracy, that sort of quality

of construction in that amount of time?

And the answer's no, which is pretty amazing that,

several thousand years later,

they're better than us.

It's humbling to think that more than 2,000 years ago

the builders of Derinkuyu possessed

engineering knowledge that exceeds our own.

And it's also a reminder that our ancestors

were far more ingenious than we often realize.

For instance, the ancient Greeks constructed

a temple that is so brilliantly designed

that it's actually able

to deceive your eyes.

High atop the Acropolis in Athens, Greece

stands one of the most magnificent

and most aesthetically pleasing structures in the world:

the Parthenon.

This 23,000 square foot temple was

constructed using 100,000 tons of radiant white marble.

The exterior of the Parthenon is lined

with 46 colossal columns,

which strikingly appear to be laid out

in the shape of an exact rectangle.

And what's more astonishing is that

the more than 13,000 stone blocks

used to assemble the Parthenon

were precisely fitted together

without the use of mortar.

How were the ancient Greeks

able to build something that looks so perfect?

The Parthenon is an amazingly beautiful structure.

The design, the spacing of each stone

is so perfect that it inspires just to look at.

The proportions are so exact for a large building

it is an amazing thing, and it lifts the spirit upward.

Built beginning in 447 B.C. on the orders of the famed

statesman and general Pericles,

the Parthenon celebrates the Athenians' victory

over Persian invaders

who had tried to conquer the city for 50 years.

Athens during the time of the building of the Parthenon is

an incredible cosmopolitan, vibrant city.

It's producing art, literature,

sculpture, architecture.

It's the Manhattan of the fifth century B.C.

And I think if you're an Athenian citizen walking,

doing your everyday work, and then you see the Acropolis

in the center of the city, this incredible shining hill,

and then you see the Parthenon, the gleaming marble,

the biggest and most beautiful Greek temple

that existed, at least in mainland Greece at this point,

you'd be filled with a sense of wonder.

Although most of the interior of the Parthenon has decayed

due to the ravages of time,

the rectangular symmetry of its exterior

looks flawless to this day.

But strangely, for a temple that was clearly built

with perfection in mind,

what makes the Parthenon so fascinating

is actually its imperfections.

Not only were the Greeks masters of geometry,

they were also masters of optical illusions.

They knew the fact that your eye plays tricks on you.

Therefore they built the Parthenon

"slightly incorrectly" to compensate for this,

so that the net result is perfection.

The Parthenon is a rectangle,

but there are no right angles in the entire building.

Everything is slightly off.

The columns look straight from below,

but they are slightly tilted toward each other.

So, if you were standing at the base of the Parthenon

and if the columns didn't stop after a certain number of feet,

but they kept on going all the way up into the sky,

you would see the columns meeting

if they were long enough to actually meet.

This is a very curious thing that the builders did.

It turns out that the Parthenon does not

have straight parallel lines at all.

The columns are not vertically cylindrical at all.

They bulge by about an inch at the center of the cylinder.

So, for example, the human brain looking at a column

will actually think that the waist is pinched.

Your eye thinks that the center of the cylinder is shrunk.

To compensate for that,

the columns at the Parthenon bulge.

There is no way this could have been an accident.

But is that all the Greeks were trying to achieve...

An optical illusion?

Or could they have had another purpose in mind

when they built the Parthenon?

Why do we create monuments like the Parthenon?

And the answer is

we want to try and imitate the divine.

The divine was seen as perfection.

The gods are seen as perfection.

And so, sacred geometry

has been incorporated into the Parthenon

in the belief that it was now endowed

with some kind of divine power.

And this was done very specifically

to connect the mundane with the divine,

to create the connection between this world and the next.

It's hard to look at the Parthenon

and other marvelous structures

from the ancient world and not feel a sense of awe

at what our ancestors accomplished.

But in the early 20th century, one man attempted

to unravel the engineering secrets

of the ancients by creating his own monuments

built entirely out of giant stones.

In this small town, tucked away between

Miami and Everglades National Park,

stands an elaborate stone edifice.

The locals call it Coral Castle.

Sculpted from massive blocks of coral,

this incredible structure features a five-ton,

heart-shaped table,

a 28-ton obelisk,

and a perfectly balanced nine-ton door

that opens with the touch of a finger.

And even more incredible than this marvel of design and

engineering is the fact that it was built by just one man,

and nobody knows how he did it.

Ed Leedskalnin was an immigrant from Latvia

who immigrated to the United States, and

he built the only modern megalithic structure ever known.

The Coral Castle is 1,100 tons of coral bedrock

that he dug out of the property on which it rests.

He was only about five feet tall,

but he managed to move hundreds of tons of coral rock

into this megalithic modern temple.

He had no technology there that could have

lifted these stones or cut the stones

and yet it's there to this day.

And the story goes that Ed Leedskalnin built this

incredible megalithic site using only a few pulleys,

a tripod, he did it all by himself,

and he worked at night, and he was very secretive.

From 1923 until 1951,

Leedskalnin perfectly shaped, lifted, fitted,

and stacked over two million pounds of limestone.

For decades, hundreds of the world's

top architects and engineers have come to this place

to solve the mystery of its construction.

The tripods, for instance, were three pieces of Florida pine,

about the same size as a telephone pole.

He used five-ton chains, he used a ten-ton chain hoist,

yet, somehow, was able to impossibly

lift stones that were wider than the tripods' diameter,

that were taller than the tripods stood,

that weighed more than the chains were rated for.

There has to be some other

technology being used here,

or this is one of the best magic tricks

ever pulled over on mankind.

So, what could it have been?

Did he learn some unique mechanical trick?

Or did he learn some new physics?

He was found often at the public library

studying the Egyptians,

studying ancient megalithic structures.

Ed said he knew the secrets of the pyramids.

I believe this to be accurate.

He was able to replicate their accomplishments,

which enabled him to be able to create something

which, by any other standard, you cannot do.

Ed claims in his notes

that he used reverse energy or antigravity.

The question is what did he mean by this?

The device that Ed used, or allegedly used,

to move these rocks were an old-school tripod

that had a large black box on top of it.

We don't know what was in that box,

and Ed never says what was in that box.

We could speculate that it's some device

that he's created that enables him to lift more weight

than he should be able to lift with this

rudimentary tripod fulcrum and lever system,

but we have no idea what it was he did.

What makes the Coral Castle so unique and mysterious

is that no one has ever been able

to replicate his results using his methods.

What this means is that he knew something that we do not know.

Did Edward Leedskalnin rediscover building techniques

used by our ancestors?

Well, if he did, he took their secrets to the grave.

So, for now, we'll continue to try

to understand just how ancient temples, churches

and tombs were constructed thousands of years ago.

And perhaps one day we too will unlock

the secrets of these extraordinary structures

that, for now, remain...

unexplained.
