Narrator: The Syunik province,

Southern Armenia.

Approximately 140 Miles southeast of the nation's

capital, Yerevan, lies the city of Sisian.

Nearby

sits a high plateau where

hundreds of ancient stones, some weighing more than 50 tons,

stretch over a third of a mile.

This is Carahunge, also known as

the Armenian Stonehenge.

estimated to be approximately 7,500 years old, Carahunge

predates the British Stonehenge

by more than 4,500 years

The site is made of 203 slabs

of basalt.

At the structure's center stands

the stone circle, or henge.

Nicholas Howarth: When most

people hear of stone henges, they think of the Stonehenge in England.

But there are hundreds of these,

uh, henges, or stone circles,

scattered all across Europe.

What they were and how they

were used is still a mystery.

Tsoukalos: Mainstream

archeology still doesn't agree

on who lived there or who the builders were of that site.

What we do know, though, is that the entire site is definitely

a part of some type of an

astronomical model.

Narrator: But how could this simple circular array of stones

have given early man information

about the stars?

Is it possible that Carahunge

might be the world's oldest observatory?

In September of 2010

England's Oxford University sent an expedition to investigate.

Howarth: What makes this exceptional megalithic monument

unique are the small holes,

which have been bored into the

rock at different angles.

There are 85 stones with holes.

They're like telescopes.

What we see with these holes is

that they are pointed at

different alignments to

positions, uh, on the horizon or

into the night sky.

or into the night sky

Uh, what they're pointing at is still a mystery to us.

But we can say with certainty from the archaeological

evidence that they were some sort of way to connect man and

his life on earth

to the

heavens above.

this with the defense on that with the same

That we can say that people were systematically trying to

understand their place in the

solar system.

Wilcock: This site is also called the Zorats Karer, which

means "the stones of the powerful."

And what has been determined is that the outline of these stones

actually does correspond to the constellation known as Cygnus,

or the swan...

which in certain cultures, is also referred to as the vulture.

Collins: Cygnus has always been seen

among cultures around the world for many, many thousands of years

as a point of entry and exit into the

sky world... this belief in a

power in the stars, the idea

that we come from the stars and

actually return there in death.

Narrator: The early Greeks, Chinese and others also believed that Cygnus had a special power or unique significance.

But why?

Why would so many ancient cultures around the world have similar myths about the same constellation?

Tsoukalos: The only reason why I would do this, if I were on a foreign planet, is to give

on a foreign planet, is to give a message to future generations

to say, "hey. Nudge, nudge.

This is where we came from."

Narrator: Although, today, it

is no longer possible to see Cygnus through the notches of Carahunge, many theories exist

as to why the position of the constellation

has changed so drastically.

Wilcock: This site dates back to antiquity,

where the earth's axis was in a different position

And you had the constellation

visible in the sky at that time

because of the fact that the

earth was on a different tilt of its axis entirely.

Narrator: Mainstream scientists have calculated that

the earth's axis slowly changes,

or wobbles, over a 26,000-year period.

But there are other researchers who believe these shifts happen more suddenly and dramatically.

They claim that when these events occur,

they cause major climate changes...

Flooding of biblical proportion...

and the widespread destruction of life

But if these rapid shifts did occur, might Carahunge have been

might Carahunge have been designed to provide something of a warning?

Wilcock: It's possible that the Armenian Stonehenge was one

of the initial sites where ETs came to visit.

And if there had been some sort of

shift on the earth's axis before, if there were periodic cataclysm

then maybe there is a time cycle in which those cataclysms happen.

And maybe these ancients were very concerned about watching the astronomical alignments

because they wanted to make sure

that this wasn't going to happen again.

Narrator: But could alien

have come to this part visitors from other worlds have come to this spot even before

Carahunge was built?

Perhaps petroglyphs in the

area... much older than the standing stones...

offer even more clues.

Howarth: The petroglyphs go back to a much earlier time, so I think my first point is

not to confuse the petroglyphs, which are from 10,000 years before Christ, with Carahunge itself.

When the stones went up, it was probably 3,000 to 2,000 years before Christ.

There are thousands, if not hundreds of thousands, of images of humanoid figures on the site.

Some of them are quite distorted

quite explicit in difficult

and difficult to understand and interpret.

Martell: The Armenian Stonehenge also has some interesting carved wall reliefs

that show humanoid-looking beings. Now, many people have speculated that these could be possibly

extraterrestrial.

We look at the very bulbous shaped heads

slanted eyes.

Very similar to what we see in a modern-day gray alien.

Tsoukalos: Look at the eyes,

look at the shape of the head.

What's interesting in this carving right here

those extraterrestrials are holding some type of a disc.

You've got this sphere that's

sort of just floating there in midair.

Is it possible that these here represent flying discs? And the answer is yes,

because again, this is a human rendering

of something that they

witnessed a long time ago.

And it had to have been compelling enough

for them to

to carve this into stone.

Narrator: Could these ancient stone carvings

actually be primitive portraits of visitors from the sky?

Did ancient astronauts really use Carahunge as some sort of

landing site or early portal? If so, what

secrets did they leave behind?

And could they still be helping to create stone monoliths, even in our own time?
