Original subtitles

- Imagine, strange creatures lurking deep

Below the ocean's surface.

Creatures, some say,

Are responsible for countless tragedies.

- The ship disappears,

All 31 crew members are lost, gone.

I know exactly what I saw,

It's a dragon in the water.

- Or shocking evidence of the undead,

Buried in a new England hillside.

The skull has been detached from the body.

- Everyone gets superstitious, is whipped up into a frenzy,

And starts desecrating graves.

- How about uncovering an entire lost city in your basement?

Little do you realize

That beneath your feet is an engineering marvel.

- These are the stories of things

That lie beneath that are so surprising,

They're truly unbelievable.

For many of us, the most disturbing answer

To what lies beneath is also the most common, the dead.

But do you know what's even more disturbing?

The undead.

- It's 1990 in griswold, connecticut,

And what is about to happen is insanely creepy.

A group of boys are playing in the woods

And they discover a human skull.

The griswold, connecticut police think it's a serial killer

And immediately cordon off the area as a crime scene.

- But once forensic anthropologists

Start doing their analyses,

They figure out that this is someone

Who was buried many years ago, in the 1800s.

As they dig deeper,

They uncover something even stranger.

- There's four burials, three of them are normal,

But the fourth, they find that the skull

Has been detached from the body

And it has been laid on top of the coffin

With the two thigh bones crossed in front of it.

In other words, like a pirate flag on top of the coffin.

- And carved upon it are the letters, jb.

- They dig down and they opened the coffin,

That's when they find this one grave,

Honestly, it looks like it

Could have been ritualistic.

You've got a decapitated skull,

You've got the ribs cracked open.

As the forensics experts do their thing,

They're able to tell that this body

Was dug up five years after death

And then dismembered and rearranged.

- They call archeologists, they call museums,

They call universities,

And finally someone tells them, well,

You know about the jewett city vampires, right?

It turns out those kids playing in the woods

Stumbled across the first physical evidence

Of something deeply irrational.

- The new England vampire panic sweeps new England

From the late 18th up through the late 19th century.

- When a death seems foggy or strange,

Everyone gets superstitious, is whipped up into a frenzy,

And starts desecrating graves,

Making sure that the dead don't rise again.

- Not entirely dissimilar from the tests

That were used in salem or in other eras with witches.

If we have a series of deaths in a village

And we have a suspected undead member of the community,

We'll exhume that body, cut it open,

Remove the heart, cut the heart open,

And if there's blood inside, bingo,

We've found our vampire.

The mysterious jb

Is just one of many suspected vampires dug up

During the panic.

Perhaps the most notorious is the poor mercy brown.

- In the 1880s, mercy's mother

And sister both succumb to tuberculosis,

And mercy is left with her brother and father.

Mercy seems fine for about 10 years, but when she's 19,

She too develops the symptoms of tuberculosis infection.

By the dawn of the 19th century,

Tuberculosis has killed one in seven people on the planet.

So there's reason to be afraid.

- Tuberculosis is not fun.

It's a bacteria and it attacks your lungs,

But it also does a lot of other terrible things.

It rots part of your body,

It can cause you to spit up blood, you can't breathe,

You get gaunt and pale,

And this sort of looks a little bit like maybe vampires.

- Mercy is being greatly diminished by this disease.

Death is on her door, but rather than having compassion

Or have mercy shown to her by her neighbors,

They think she was the source of her mother

And sister's death a decade before,

And they accuse mercy of vampirism.

That resentment continues even after she dies.

Though she's dead and buried,

The entire village remains terrified.

- It just so happens that mercy's brother

Is also ill at this point,

And the neighbors think mercy is coming back

To feed on her family members.

They convince her father to exhume the bodies

So that they can examine them

For what they believe will be proof of vampirism,

Namely that there will still be blood in the heart.

So they open the graves of mercy's mother, sister,

And mercy's grave as well.

Of course, her mother and sister

Have been dead for 10 years.

There's no blood left in their hearts.

Mercy's only been dead for a little while,

So of course, when they open her chest,

Her heart still has blood in it,

And they determine she must be a vampire.

And how the villagers plan to stop

The vampire virus is, well, merciless.

- They take mercy's heart, they burn it,

Those ashes are then fed to her younger brother

As basically a vaccine against vampirism.

- Hopefully at this point in time he's too fevered

To recognize what was happening.

But mercy's scorched heart can't save her brother,

And two months later he too dies of tuberculosis.

- Mercy's story is well covered in the media,

It goes global.

- Following these events, bram stoker is writing

His soon to be world famous novel "dracula",

And there is supposition

That mercy brown is translated

Into the story of lucy who also withers away

And then returns as a child of the night.

- But what legend inspired stoker's infamous blood sucker?

Most believe it was an actual medieval prince,

One with a very real thirst for blood.

- Vlad the impaler is the original dracula.

And he does execute people in nasty ways.

He's famous for impaling alive his enemies.

- He will go on to earn his moniker,

The impaler, where he would kill,

According to greek historians, upwards of 80,000 people,

More than a quarter of whom were impaled.

Tales abound of vlad dining

Among his impaled victims,

Even dipping his bread in their blood.

- Some reports even say that vlad drinks the blood

Of his enemies, which would make him the closest thing

We have to, well, a real vampire.

The question is what caused this unholy bloodlust?

- Early in his life,

Vlad the impaler is imprisoned for political reasons.

According to lore,

Vlad spends years in an underground dungeon

In a castle called tokat.

- He develops this taste for impaling rats,

Essentially conducting certain kinds

Of grotesque experiments on the corpses of rats.

Mind you, if you were incarcerated in a dungeon

Or dark, damp cave underneath a castle for years on end,

You might go a little bloodthirsty yourself.

Makes a weird kind of sense,

But most historians write off this story,

Because the castle where vlad was imprisoned

Doesn't have dungeons.

At least that's what they think until 2014.

- The historical site of tokat castle in turkey

Is finally excavated,

And the archaeologists discover something

That they never thought they'd find

In a million years, tunnels.

Tunnels that lead to two hidden dungeons.

- They start to realize this was a place

Where people were imprisoned.

- They put two and two together

And realized that these tunnels

And dungeons closely matched the accounts of those

Where vlad and his brother suffered torment.

Does this prove that the tales

Of the real life dracula are actually true?

- So this chance discovery in tokat castle

May actually be the connection

That we need of the dungeons and the terror experienced

By vlad the impaler that led to the inspiration

For bram stoker's prince of darkness.

- Dungeons, the undead,

What else could lie beneath?

As we'll find out, the deeper you go,

The stranger it gets.

- The age of exploration opened the world's eyes

To just how vast the planet's oceans are.

It also opened the door to many questions,

Like just how deep are those waters

And what the heck is down there?

- In 1875, the hms challenger is circumnavigating the globe

In what was really the first great oceanographic expedition.

- Pretty big adventure here.

They're making the first charts of the ocean, if you will,

And this is pretty important.

So they roll up to the area called the mariana trench,

And they drop a line, and it keeps going and going.

With five miles of rope on board,

The crew figures they have plenty to reach the bottom,

Until the unbelievable happens.

- They run out of rope

And they can't actually get the exact depth.

- And then 76 years later in 1951,

The hms challenger ii goes out.

Do they bring a bigger piece of rope this time?

No need when you've got sonar.

What they find shocks the world.

- The challenger ii measures the mariana trench

To be seven miles deep.

It is officially the deepest part of the ocean.

- It is also the deepest place on earth.

- Let's put how deep this goes in perspective.

It's as if you stacked 25 empire state buildings

On top of each other, that's how deep this is.

That's pretty deep.

So deep it makes curious explorers worldwide wonder,

Can anything live there?

- The first ones to take the plunge are oceanographers,

Jacques piccard and don walsh in 1960.

- And they get in this thing called the bathysphere

That descends underwater.

- These guys get down to the bottom,

They see what appears to be a barren landscape.

The pressures are so great,

There's no light to support photosynthesis.

But when they look more closely,

They see that there

Actually is life.

- There is life at the bottom.

I mean, this is unbelievable.

This changes everything people know

About what is happening in the ocean depths.

After a three hour ascent,

The divers return to tell their tale,

But now there are new questions.

How many creatures are down there

And how on earth do they survive?

- Most of the life that we see in the ocean lives

Within the first 600 feet where the waters are warmer

And there are kind of thriving ecosystems based on the sun.

Below that, you enter the twilight zone

Where not a lot of light filters down

And the ecosystems are kind of different.

Below that, it's pitch black,

And you get into alien worlds like something out of space,

But they're happening right here below the ocean.

- The creatures that live down there

Sound like creatures of darkness, vampire squid,

Zombie worms, goblin sharks.

- One of my favorites is the dragon fish.

And the coolest thing about them

Is that because it's so dark down there,

They don't really use their eyes that much,

But they've evolved to use bioluminescence.

And so along their face and their jaw,

They have these little spots

That light up in different colors.

And that actually attracts smaller fish,

Which when they approach the mouth of that animal,

Become a meal.

To say the trench's temperatures fluctuate

Is an understatement.

It can range anywhere from a chilly 34

To a scalding 700 degrees fahrenheit.

- At those depths,

There are also vents into the earth's crust

That release boiling hot water.

And believe it or not, there are actually creatures

That are also evolved

To survive in those extreme conditions as well.

- I'd say that the coolest thing about the trench

Is that it still remains largely unexplored.

We've landed more people on the surface of the moon

Than we have in the depths of the mariana trench.

So there is so much more there to find.

There are more surprises to come,

And more evil, deadly creatures to discover.

- Just off the coast of japan dwells a creature legend calls

Both evil and deadly,

One that lies hidden

Deep beneath these treacherous waters.

- There's this area of the pacific ocean

That's between japan, taiwan,

And yap island that could give the bermuda triangle

A run for its money.

It's called the devil's sea,

And it has a ton of shipwrecks and disappearances,

but according to chinese legend,

It's not the ocean that's to blame.

- 3000 years ago, chinese sailors tell stories

Of this huge undersea dragon pulling ships underwater

And feasting on their crews,

Which is how the area gets its other name,

The dragon's triangle.

The dragon's triangle continues

To claim countless victims over the years,

Including a hoard of fearsome 13th century warriors.

- The conqueror, kublai khan,

Who is the grandson of genghis khan,

Decides to invade japan.

And according to records,

Lost 40,000 sailors to shipwrecks

And determined to discontinue his planned invasion

And to stay away from the dragon's triangle.

The place is considered too dangerous.

So what actually destroys kahn's massive armies?

Some say a typhoon, others say the gods,

But khan himself thinks something different.

- Kublai khan and and his advisors believed

That their navy was swallowed by a sea dragon.

Even one of history's most fearless warriors

Was rattled by these waters.

The legend endures well into the 20th century,

Galvanized by an eyewitness account during world war ii.

- It's now 1944, and in the heat of a naval aerial battle,

Japanese airman, toshiaki lang,

Swears, as he looks down,

That he sees the loch ness monster-like head

Of a giant sea serpent.

In his after action report, toshiaki says to his superiors

That the beast was at least 150 feet long

And used giant triangular wings to paddle

Its way through the tumultuous seas.

- He's pretty indignant about this,

Because when he mentions it,

People think, "have you been drinking a little bit?

Or maybe you're mistaking it for a submarine."

And he's like, "I know exactly what I saw.

It's 150 feet long, this thing is a monster,

It's a dragon in the water."

the pilot's warning is brushed aside.

But after nine more ships vanish in the devil's sea

Between 1946 and 1951,

The japanese government

Can no longer ignore

That what's happening

Here could be fishy.

- In 1951, the maritime safety agency assigns

The task to a research vessel known

As the kaiyo-maru no. 5.

And what happens?

The ship investigating the disappearances disappears.

All 31 crew members are lost, gone.

- So the japanese government decides

That maybe investigating this is not the best thing to do.

So what they do is they just issue this thing called

The notice to mariners and they say, okay,

Just officially avoid this area,

'cause bad things happen.

Even with the warning, ships continue to vanish.

Some say as many as a thousand since 1951.

- One thing seems certain,

No matter what you think causes these problems,

Whether it's rogue super waves,

Or underwater volcanic activity,

Or here's another favorite theory, methane gas eruptions,

Or here's another favorite theory, methane gas eruptions,

Something weird is happening in the dragon's triangle.

Something weird is happening in the dragon's triangle.

- If you know where to dig, all kinds of strange

And interesting things can be uncovered,

But sometimes it's the hole itself that's the mystery.

- In the early 2000s, geologist heinrich frank

Is driving in novo hamburgo in southern brazil.

And he passes a construction site,

And something catches his eye, something weird.

He sees this tunnel. It's a hole about 15 feet wide.

This is a Friday afternoon and he has to keep driving.

But frank thinks about this all weekend.

I mean, what is it?

Is it a tunnel?

Who made it?

Where does it go?

Why is it there?

- He can't stop thinking about it.

So a few weeks later,

He goes back to the

Site to investigate.

He goes up to this tunnel that is leading underground

And he starts walking into this giant 15 foot hole.

- And right away he notices something weird.

Remember, he's a geologist,

He knows that earth shaped by water

Is not gonna create a perfectly round opening.

So this is an odd thing.

- As he walks into this tunnel, the deeper he gets,

He looks up at the ceiling,

And he's noticing these giant claw marks.

Even as a geologist,

Frank now understands the chilling reality.

He's standing in the home of something very big

And very deadly.

- These look like the homes of giant jungle creatures.

And frank wants to know what kind of creature

Makes a tunnel this big?

Local paleontologists are thrilled to share

That these huge burrowed tunnels

Are the work of giant prehistoric sloths.

- When you think of a sloth today,

You think of something that is slow and beyond adorable.

But these prehistoric giant sloths,

They put today's sloths to shame.

- The extinct giant sloths all belong

To the genus megatherium, which is an awesome word,

That I think sounds like the name of a heavy metal band.

These are huge animals.

They can be 10 feet long and weigh 2000 pounds.

That's a ton.

And they have these huge, long, hooked claws.

They're nine inches long.

Think about your kitchen knives,

Now imagine that being on the end of the hands

Of these animals and them using it

To pull tree branches down to their mouth.

They can also use those claws as a form of defense.

Turns out those same claws

Are the perfect tool to dig giant burrows in the ground.

- So frank, super curious guy,

Starts using satellite imagery

To map out these network of tunnels,

And he finds out there's not just one, not just two,

There are 1500 separate tunnels that are kind of snaking

Through this southern brazilian area.

I think it's incredible that these 2000-pound creatures

That once roamed the earth,

That there's still evidence of them, like,

Next to a construction site.

It's wild.

- Created more than 10,000 years ago,

Today these ancient tunnels feel

More eerie than frightening.

Now, that's not the case

With a mysterious cave in the americas.

Here it's not the size that matters, it's what's inside it.

- In the jungles of yucatan, mexico,

Near a place called kantemo village,

There is a cave that could only be described

As a living nightmare.

- So you go into this cave, it's a 65-foot mouth,

But it narrows a little bit.

And once you get into this narrower part,

There are things hanging from the roof of the cave.

They kind of look like vines,

But they're not vines, they're snakes.

- It's the yellow-red rat snake.

And there's this one population of them

That have evolved to live only in this cave.

- At night, when the bats leave,

They leave in this giant drove.

And the snakes see this opportunity as dinnertime.

Tucked into the crevices of this cave,

They'd open up their mouths and pretty much allow the bats

To impale themselves on their fangs.

It's easy picking, especially with the amount of bats

That are in this cave.

- And there are so many of the bats

In this particular cave system

That this population of snakes has learned

That they don't ever need to leave the cave.

- They're very aware of the time of day.

They know when the bats are gonna be coming out,

And they actually get themselves into position.

So it just goes to show you

That these are actually very intelligent creatures.

Believe it or not, visitors are actually welcome

To tour this dangling hall of terrors.

- I've been to the cave of the hanging snakes

And it is one of the eeriest

Places I've ever been to.

The ceilings are very low,

And as a human inside that cave, you have to crawl in

With your head nearly touching the ceiling,

And then hundreds, hundreds of snakes coming out

Of the ceiling to catch little bats,

Grab them with their mouths, and back up into the ceiling.

It is the definition of a living horror movie.

- No, thank you.

This is my nightmare.

This is my nightmare, cave with the hanging snakes.

This is my nightmare, cave with the hanging snakes.

That's one cave you won't find me hanging around.

- Sometimes what hides beneath is neither deadly nor evil,

But rather a glimpse into a mysterious past.

Take this astonishing find by a miner in 2022.

- In the klondike gold fields of

The yukon territory of canada,

You have a man by the

Name of travis delawski.

He's working in a trench

And in this trench you have this creek

That is covered with permafrost that's sitting on the top layer.

- As travis is chipping away at the rock hard ice,

Suddenly a crevice opens.

- Inside, he discovers something strange,

Some kind of creature.

He sees a short tail

And at first he thinks it's a mummified buffalo calf.

But as travis looks more closely,

They see something a buffalo doesn't have, a trunk.

- So he immediately calls his boss to try

And figure out what the hell he just came across.

So the boss comes down to see what travis actually find,

And he's shocked.

He sees fur and it looks like it died maybe an hour ago.

So he immediately yells out

For everyone in the trench to stop working.

And he takes some photos with his phone,

And then he calls some local paleontologists

To come in and inspect the scene.

When they see the photos,

They confirm the unbelievable.

It's a baby woolly mammoth straight out of the ice age.

- And they're all hands on deck,

And they have to act immediately,

Because once this woolly mammoth baby is exposed

To the elements, it can start to deteriorate.

And there's a storm coming

That is gonna totally flood out the trench.

With moments to spare,

They manage to get the woolly mammoth baby out.

They carefully wrap it in a tarp,

And then they transport it to a location

Where they actually have a ceremony

With local indigenous elders.

Gathered in a circle, the tribal elders offer a blessing

And name the mammoth nun cho ga,

Which means big baby animal in their native haen language.

With the clock ticking,

Scientists must examine the baby mammoth quickly

Before getting it into a freezer for preservation.

- But they're able to determine that nun cho ga is a female,

And she was only about a month old when she died.

They estimate that she died around 30,000 years ago.

- The geology of where the mammoth is found indicates

That she was walking across the grassland,

Strayed from her mother,

And then she fell,

Gets stuck in the mud,

And is preserved under tons of permafrost to be found

By us thousands of years later.

Incredibly, they find a piece

Of grass in the woolly mammoth's stomach.

Fortunately, this means nun cho ga died quickly.

- While it's sad that nun cho ga only lived about a month,

Her discovery today is really incredible.

- This is the most intact mummified ice age animal

Found in north america, if not the world.

- While a 30,000-year-old creature trapped beneath the ice

Might be fascinating, something terrifying lies

In an otherwise enchanting setting,

Something that has locals afraid to go anywhere near it.

- This place is 25 miles south of merida

In an area surrounded by dense jungle.

There's this little opening,

This hole, which enters into a void,

And inside this void is a drop into an abyss

Of watery darkness.

It's called sac uayum,

And it's one of at least 40 cenotes, or underwater caves,

That lie beneath this mysterious region.

They collect so much naturally filtered groundwater

That in the 13th century the mayans decide

To build their new capital here, mayapan.

- This walled city of like 17,000 people thrives

For centuries, and it has dozens of life sustaining cenotes

Inside the city.

- Most of them are within the walls of mayapan,

Except for one,

That for some reason the walls zigzagged around

And moved around to avoid having

That one cenote inside

Their city, sac uayum.

- They believe sac uayum is a sacred place,

A pathway to the underworld.

The maya also believed that this place is guarded

By a feather covered serpent with a horse's head,

Who will snatch children who get too close.

- I've personally visited mayapan,

And wanted to go to sac uayum,

And every villager I have met have told me their story,

That they have seen a snake-like creature that flies

And has a horse head that is guarding that place,

And I should not get anywhere close to sac uayum.

Is it possible

That sac uayum's legendary feathered serpent is real,

Or at least once was?

In August of 2013, archaeologists,

Led by dr. Bradley russell attempt to find out.

- You can imagine that getting in

And out of a sinkhole that has a 40-foot drop

Is quite difficult.

So they basically have to be lowered down into the water

And then they can start their dive.

But remember, if something goes wrong,

You gotta be hoisted back out that 40 feet.

You're being slowly lowered,

Now you're in this dark, murky water,

And you know you have to actually penetrate through

And go into a cave.

- As bradley and his team scuba

Through these tight passages,

Their tanks are hitting the limestone,

I mean, it's so tight.

That's where they discover human skeletons.

Could these be ancient victims

Of the notorious serpent monster?

- There are just dozens of skeletons of men

And women in this place.

In mayan civilization,

We do not have evidence of mass graves or mass burials.

These people seem to be in the prime of life.

There's nothing that shows, for example,

Damage through warfare to the skeletons.

And there's nothing that suggests

That they're victims of human sacrifice.

So the fact that in this cenote there are dozens

And dozens of human remains makes it a bit of a mystery.

We don't know why these people ended up in this cenote.

- Whatever science might eventually uncover here,

Many of those who live by sac uayum believe

Many of those who live by sac uayum believe

The legends are true,

And that this mysterious pool is indeed an entrance

To the underworld.

- The city of paris is known for romance,

Art, and cafes.

But below its charming street lies

Something quite different,

Miles of tunnels stuffed with human remains.

- The tunnels themselves are the result

Of limestone quarries that are dug around the 13th century.

But quarrying was unregulated.

People just dug where they wanted to

And then when the limestone ran out,

The tunnel was abandoned.

So by the 18th century,

This part of paris was like swiss cheese.

By 1780, the city of paris is left

With nearly 200 miles of abandoned mining tunnels

Beneath its streets,

Until they find a dark, new purpose.

- Parisian cemeteries are literally overflowing.

Graves are buried on top of graves on top of graves

On top of graves.

- It gets so bad that a building next

To the cemetery has its basement wall completely collapse,

Because there are so many bodies

On the other side of the wall.

- The paris city officials realize

Something has to be done.

They think, what we really need

Is a good underground storage area,

And we have one, all of those limestone tunnels.

- So in 1786, thus commences

The most macabre public works project of all time.

Wagon upon wagon

Upon wagon cloaked in black cloths are shipping bones

From the cemetery down into the disused mines

To create the paris catacombs.

We're talking about millions upon millions of human remains.

Today, visitors can tour this bizarre display

Of over 600 years of the dead.

- There's an official door to the catacombs

Where you can pay and you can go tour

A certain small section of the catacombs.

But not everyone sneaks down there to gawk

At old bones.

- The catacombs also plays host

To a very interesting and amazing heist.

A team of people start going down through the catacombs,

Using the tunnel as a means of getting

To a very fancy luxembourg apartment.

They drill up 20 feet in order to get into this apartment.

What's there are really expensive bottles of wine,

Each bottle at least $1,000, and they steal 300 of them,

And disappear back down into the catacombs,

Just melting into the darkness.

The wine thieves are never found,

But it's not even the strangest secret use

Of this underground labyrinth.

- The paris police department

Has a unit to patrol these tunnels,

And they regularly go down there to train.

They're going along this dark tunnel

And they suddenly see a sign that says,

Building site, no access.

And they haven't been informed of any kind

Of city construction project happening underground.

So they push through this tarp to find out what's beyond.

- They lift the tarp away to find a security camera,

And suddenly dogs begin barking from everywhere.

They don't turn out to be real dogs.

It's pumped through speakers to frighten people away.

But that makes it even more intriguing.

Who is trying to keep us out of this space?

What they find is truly bizarre,

Even for catacomb police, a movie theater.

- Not only that, this movie theater has attached

To it a fully-featured restaurant and bar.

Not only that, it has telephone lines.

So that means someone knows the reservation number.

They're like, "hi, secret bar?"

They're like, "yeah?"

Like, "table for four?"

"yeah."

this underground theater is obviously illegal.

But when police return three days later,

They get another surprise.

- They come back, everything's removed,

And there's a sign that says do not try to find us.

- A photographer named patrick alk,

Whose whole thing is to document

The underground exploration movement.

Is disappointed that the movie theater got busted,

But he says, "you know,

No problem, there are dozens more where this came from.

You guys have no idea what's down there."

- Finding unusual things in your basement

Is fairly common for most people.

But what one man finds in his home in turkey, unbelievable.

- In 1963 in the turkish town of derinkuyu

A man is doing a home improvement project.

Now, most of us who do this kind of diy stuff,

You expect to find old stuff in the walls,

You know, old photos and maybe some jewelry.

Well, this guy takes his sledgehammer

And he hits the wall

And he hits it again and again, and he breaks through.

What he finds is a passageway,

Which, when he crawls into it,

Leads to another tunnel and another tunnel beyond that.

- And the tunnel goes on a little bit longer,

And a little bit longer, and then opens into chambers,

And then more chambers and then more tunnels.

He's discovered an ancient subterranean city

Right in his cellar wall

All through the throw of a sledgehammer.

It's the 2000-year- old lost city of derinkuyu,

One of the largest subterranean towns in the world.

- What he uncovers is absolutely unbelievable,

A tunneled city that can house up to 20,000 people,

Animals, livestock, grain stores.

The first eight stories have ventilation shafts

That ensure that fresh air circulates

Through the entire subterranean city.

- They've dug out troughs

For the camels that are down there.

They have large vats for the wine that they're fermenting.

All of this is dug of the stone itself.

It's very, very resourceful.

But why build such an elaborate city underground?

- The main purpose of this underground city

Is for the people of derinkuyu

To come in and hide from outside forces,

From dangerous people who may have infiltrated the area.

- One of the most amazing sites is there

Are these huge millstones

Which are in place still to this day.

They have a round hole in the middle

And you can roll this millstone into place,

Which would then block the tunnel

And stop the enemy from going any further.

This defense system works so well,

The city remains in use until 1923

Before it's sealed up and nearly lost to history.

Good thing for diy projects.

- If you're just walking in one of these areas

With one of these underground cities,

Nothing looks different.

I mean, it's just life as normal on the surface.

Little do you realize

That beneath your feet is an engineering marvel.

Makes you wonder what unexpected things

Could be on the other side of your own basement wall,

Or in your own backyard.

- In 1974, a plumber named rosendo cruz from alhambra,

California, buys his wife a brand new ferrari dino

For her birthday.

She's so excited, she can't wait to take it out.

They cruise on out to the brown derby

To have a birthday dinner, have a wonderful time,

Come outside the restaurant, and the ferrari is gone.

- Police are never able to find the dino,

And ultimately, it becomes a

Cold case that's unsolved.

- Four years later,

You have a couple of boys playing in the backyard,

And these boys decide, let's

Dig up stuff in the backyard

And see if we can find some buried treasure.

And then their shovels start to make a clinking sound.

No, did we hit a pipe?

So they immediately run out

And they flag down an la county sheriff's cruiser.

- The policeman contacts the city,

They bring out a bulldozer and begin to dig,

And lo and behold, what do they excavate?

A 1974 ferrari dino 246 gts,

The same ferrari dino that was parked

Outside the brown derby four years ago.

But after a little more digging,

They noticed something totally unexpected.

- So when investigators uncover the car,

They find that it's been

Almost impeccably preserved.

It's been wrapped in plastic, and tarp,

And even blankets, and someone clearly wanted

To maintain this car.

- Another thing that helps preserve the vehicle

Is that it's in southern california where it's dry.

And during this time, there was actually a drought.

So they basically made a ferrari mummy.

No one was ever charged for the theft of the dino,

Though theories abound as to who stole it

And why it was left there.

Maybe the thieves just forgot where they put it.

But even after four years underground,

This dino isn't destined to just be scrapped for parts.

- Believe it or not, to this day,

The dino still lives.

After it was recovered, it was sold to a collector.

He decided to keep as much

Of the original materials as possible.

It still has two of the original wheels,

The original chrome, and today it sports

A license plate that says, dug up.

- Whether it's a perfectly preserved baby mammoth,

Mysterious bones, or a vintage ferrari in mint condition,

What lies beneath us is fascinating, terrifying,

And sometimes, unbelievable.
