Unearthed (2016–…): Season 6, Episode 6 - Hitler's Lost Bunker - full transcript

The long-lost underground bunker of Adolf Hitler is home to some of the greatest secrets of the Nazi regime, and now, experts use cutting-edge tech to discover new evidence of Hitler's evil vision for global domination.

Narrator: Berlin, germany...
The headquarters

Of one of the most
feared leaders in history...

[ speaking german ]

Narrator: ...Adolf hitler.

In this underground
nazi stronghold

Known as the fuehrerbunker,

Hitler plans world domination.

This was where hitler played out
the final scenes

Of the second world war.

Narrator: Do any traces remain
of the bunker

Where hitler made
his last stand?

Dunkley: For the last
hundred days of his life,

Only twice did
he ever come out again.

Narrator: And how was
the fuehrerbunker engineered

For hitler to wage a war?

To find out,
investigators shine a light

On abandoned
nazi megastructures...

It's truly a massive space,
cathedral of war.

Narrator: ...And use innovative
laser scanners to reconstruct

The last days
of the third reich.

I think we can say that this is
some kind of super bunker.

To solve these mysteries,

We'll blow apart
hitler's wartime bunker

To reveal how he commands
his third reich

From 20 feet underground.

We'll discover hitler's secret
subterranean strongholds

And unearth the hidden heart
of his nazi regime.

EP - 6 - Hitler's Lost Bunker

Berlin, capital of one of
the most evil empires

Of the 20th century,
adolf hitler's third reich.

Deep underneath
these city streets

Lies one of the most significant
structures of world war ii,

Hitler's bunker.

Hitler's bunker is a source

Of great fascination
around the world.

You know, we're trying to still
get our heads around ultra evil,

And this is one of the key and
most important historical sites.

Narrator: In modern-day germany,

Remains of hitler's
brutal nazi regime

Are there to be found,

But only if you know
where to look.

Hidden somewhere
below the streets of berlin

Lies hitler's bunker,

Known as the fuehrerbunker.

It's a 3,000-square-foot complex
of top-secret rooms.

On the upper level,
a maze of 19 small rooms,

Some only six feet wide.

And eight feet deeper,
the heart of the bunker,

Hitler's command center.

His private wing,

Just a small office and bedroom

Protected by an immense
concrete ceiling 15 feet thick.

But where is
hitler's bunker today?

In April 1945,

Russian troops overrun berlin.

They find hitler's body

Just yards away
from his fuehrerbunker.

Decades later, hitler's bunker
is a violent footnote

In german history
most would like to forget.

But military historian
nigel dunkley

Is determined to seek it out.

The bunker was so sensitive

Nobody wanted it to become

A rallying place
for perhaps neo-nazis,

And so the decision
was made to eradicate it.

Get rid of it.

Narrator: Hitler's bunker is
consigned to germany's past,

But nigel believes
he can connect the dots

To lead him to its location.

So, I've got with me
a famous photograph,

And it shows the reichskanzlei,
the reich chancellery,

Hitler's office at the end
of the war in 1945.

Narrator: The reich chancellery
is hitler's official residence.

Dunkley: This was the absolute
epicenter of nazi power here.

440 yards long...
It was massive.

It was here to impress people

As well
as being a functioning office.

Narrator: The reich chancellery
is demolished

After world war ii.

Like the bunker, its former
location isn't advertised.

Dunkley: Here we are.

Right slap bang in the middle

Of where hitler's chancellery
used to be.

And in the back garden,
below it, hitler's bunker.

And that's exactly where
we are standing right now.

Europe's most interesting
car park.

Narrator: What was once
the epicenter of nazi power

Is now a parking lot.

But hitler's bunker starts life
as something very different.

Hidden beneath
the reich chancellery ballroom

Lies an air raid shelter,
72 feet long.

Two entrances allow
a rapid retreat

From both sides of the building.

Inside, there is enough space
to accommodate hitler

And 200 staff
during a bombing attack.

A snaking system of pipes
delivers filtered air

To protect them from poison gas

And a 5-foot-thick roof

Provides shelter
from the impact of bombs.

This air raid shelter is merely
phase one of hitler's bunker,

But how does he build
this subterranean shield?

Historian sascha keil
thinks the answer

Lies hidden
beneath berlin's streets

In a labyrinth
of secret nazi tunnels

That make up a vast underground
city over 600 miles long.

To unlock the secrets of the
fuehrerbunker's construction,

Sascha explores
an abandoned tunnel

Less than half a mile away.

Just navigating these tunnels
can be dangerous.

At the bottom of the shaft,

Sascha discovers the remains
of a huge road tunnel.

It was built by
hitler's nazi engineers in 1938.

What can this 60-foot tunnel

Tell us about the construction
of hitler's bunker?

Sascha believes these tunnel
builders encountered trouble

As soon as they begin to dig.

But hitler's nazi engineers
have a solution.

Berlin's soft, sandy soil

Makes building underground
difficult and dangerous.

Tunnels and trenches
can't support their own weight

And collapse inwards.

So, engineers use steel mesh and
beams to reinforce tunnel walls

And fill them with extra-strong,
quick-setting concrete.

Concrete like this is essential

When building underground
in berlin.

But is it the only problem
hitler's engineers

Have to overcome?

In the underground
nazi road tunnel,

Sascha can go no further.

Berlin has a very
high water table,

And parts of this road tunnel
are flooded,

But hitler demands his bunker
be built here.

So, how do the nazis overcome
this next engineering hurdle?

Building below the water table
is a massive problem

For hitler's engineers.

However fast they dig,

The trenches
quickly fill with water.

So, they install pumps
that run 24/7

To suck out water
during construction

So they can carry on building
without delay.

Hitler's water pumps mean
it's full steam ahead

For the construction
of the fuehrerbunker.

His concrete and steel walls

Are vital for withstanding
allied attack.

With these additional

Hitler is going to incredible
lengths to protect himself.

But will it be enough?

Or does his fuehrerbunker
have a fatal flaw?

Berlin... home to the secret
underground bunker

Of adolf hitler.

At the very height
of world war ii,

British and american bombers
pound the city.

The allies know
if they can kill hitler,

The war will be won.

Murray: During the war,

There was sort of
a miniature arms race.

The germans built more and more
heavily defended buildings,

And the allies built larger
and larger bombs

In order to attack them.

Narrator: Unnerved, hitler
orders his reich chancellery

Air raid shelter
to be strengthened.

Phase two of
hitler's bunker begins.

To extend hitler's original
air raid shelter,

Engineer's dig
a 10,000-square-foot box.

They lay a 7,000-ton
concrete base

And build
steel-reinforced walls,

Each filled with
12 feet of concrete.

On top, thick steel beams
covered with a fine steel mesh

Reinforce the walls
against explosions.

Finally, it's submerged
in concrete

To create a new roof
that is 15 feet thick.

This is engineering
on a grand scale.

Could hitler's bunker
be destroyed?

Iain murray is an expert
in world war ii weaponry.

He wants to investigate
if hitler is safe

In his new and improved bunker.

Iain explores this
abandoned u-boat factory

Near bremen, germany,
to discover

How effective
the allies' bombs truly are.

The nazis were developing more
and more sophisticated u-boats.

This bunker was built
to build the latest version

Of the u-boats.

And it was
massively constructed.

Just like hitler's bunker,

This gigantic factory

Is built completely of
reinforced concrete

With a roof and walls
that are 15 feet thick.

Murray: The nazis were
exceptionally well developed

In building
massive concrete structures,

Which were impervious to most of
the bombs which the allies had.

Iain explores the building
for signs of allied attack.

On the roof, he makes
a startling discovery.

Well, all over this roof,

There are these huge craters.

And these have been made
by penetrating bombs,

Which have come down and hit
the roof at incredible speed

And penetrated
right into the concrete.

Narrator: The explosive device
responsible for

Some of these craters

Is the bunker-busting
disney bomb.

Rumored to be named after

A disney world war ii
propaganda film,

This bomb weighs
more than 4,000 pounds.

Fitted with rocket motors,

It slams into its target
at over 1,000 miles per hour.

The allies were hoping that
the disney bombs

Would help to knock out
installations like this.

But this bomb has a weakness.

Murray: Because the disney bomb
was propelled

By a rocket motor on the back,

That tended to wobble the aim
of the bomb a little bit.

They were much harder to drop
with good accuracy.

The american air force dropped
60 disney bombs on this target,

And only two of them
actually hit it.

Narrator: The disney bomb
barely scratches the surface.

The allies need something
bigger and better

If they're going to bust
hitler's bunker.

Enter the grand slam.

22,000 pounds
of explosive power.

It's one of the most devastating
weapons ever designed.

This mega bomb
has one purpose...

To annihilate
the nazi war machine.

Traditional bombs
are designed to explode at

Or near the surface,

And destroy their target
directly by explosive force.

Earthquake bombs like the huge
grand slam are different.

With extra-thick shells,

They're designed to survive
impact with the ground.

Shaped to fall
at very high speed,

They penetrate the surface
and explode deep underground,

Sending out powerful shock waves
like an earthquake.

They cause huge destruction,

Both above and below ground.

The allies hope the grand slam
will turn the tide of the war,

But can it really
bust hitler's bunker?

Iain heads inside the abandoned
u-boat factory to find out.

It's truly a massive space.

A cathedral of war.

So this hole in the roof
was created

By a grand slam 10-ton bomb.

That bomb has come down,

Hit the roof traveling faster
than the speed of sound,

Penetrating deep
into the concrete,

And then it's exploded
and left a hole

About 20 or 30 feet
in diameter in the roof.

Narrator: The grand slam's
direct hit

Blasts straight through 15 feet
of reinforced concrete.

But what if this bomb
had hit the fuehrerbunker?

So even if the fuehrerbunker
hadn't been hit on the roof,

If the bomb had landed
within 50 meters,

The shock from the explosion
would have damaged the bunker.

It would also have killed
a lot of the people

Inside the bunker as well.

And if hitler was there,
we would have got him.

Narrator: Iain is certain
hitler's new reinforced bunker

Would have been no match
for the grand slam.

Hitler is a sitting duck
in his berlin bunker.

The allies are closing in,

And they have a bomb
that could kill him.

If hitler is to keep
his war command running,

Nazi ingenuity
will be put to the test.

Can he ever build
a bunker strong enough?

Narrator: The bunker hitler
builds in the heart of berlin

Is vulnerable
to allied mega bombs.

But by 1943,
hitler's nazi legions are locked

In a desperate struggle
with soviet russia.

It's one of the biggest

Waged in human history.

And hitler builds another bunker

Here, in nazi-occupied poland,

Just 90 miles
from the russian front line.

This new bunker is at the center
of a huge military complex

Called the wolf's lair.

Architectural historian
robert conrad

Explores this site to see
what makes this bunker unique.

Partially buried,

With a roof
more than 25 feet thick,

This colossal bunker
is engineered

For hitler's
ultimate protection.

Designed like an egyptian tomb,

The living quarters are buried

Under dozens of feet of sand,
steel, and concrete.

Hitler's bedroom,
measuring 9 feet by 11 feet,

Sits among a maze of corridors
and other tiny rooms.

This concrete fortress
is camouflaged with grass

And nestled in dense forest.

Has hitler finally built
the perfect bunker?

Robert believes the answer
can be found among these ruins.

Hitler's bunker at the heart
of the wolf's lair

Is more than 26 times the size
of his bunker in berlin.

Hitler's wolf's lair is designed
for maximum security.

The forest hideaway is laid out
in three concentric rings.

At the heart of the complex
is security zone one.

It houses reinforced
concrete bunkers for hitler

And his inner circle.

Security zone two houses
lower-ranking ministers

And the barracks for the ss.

Security zone three is the
heavily fortified outer ring.

It's defended by guardhouses,
watchtowers, and checkpoints,

And surrounded by land mines.

The wolf's lair
is close to the front line

And is heavily defended.

But if hitler is going
to win the war,

He'll also need protection
from air attack.

The tree cover provides
the perfect natural canopy

To hide hitler
from allied bombers.

And at the fringes
of the wolf's lair,

Robert discovers
something else...

Train tracks.

Hitler has created
the perfect bunker complex

Here in the vast forests
of northeast poland.

But the war turns
against the nazis.

Hitler's wolf's lair lies in the
path of the advancing soviets.

He must retreat.

The protection of the fuehrer
is proving

The most important
security challenge of all.

What can hitler
and his engineers build

To keep him safe
from the advancing enemy?

Narrator: Deep in the woods
of nazi-occupied poland,

Hitler and his armies are
waging war against the allies,

But the war is turning
against the germans.

The soviets are advancing
into poland.

Hitler is forced to abandon his
secret military bunker complex,

The wolf's lair.

He needs a new command center.

A mammoth construction
is ordered

Beneath the stunning
ksiaz castle in southern poland.

It's code name... giant.

Concealed deep in the mountain

Is a vast network
of secret nazi tunnels.

Starting at the castle,
the shaft from the fourth floor

Plunges down 130 feet,

Splitting into multiple routes.

Inside, some tunnels
are neatly lined with concrete

And wide enough for armored
vehicles to drive through.

But 40 feet deeper,
some passages are unfinished.

Roughly cut into the bare rock,

A maze of tunnels carved
deep into the mountain.

What is hitler building here?

To find out, mining surveyor
mateusz jablonski and his team

Head directly
beneath ksiaz castle,

One of the largest castles
in poland.

For the first time,

Mateusz's team
will digitally map

This twisting labyrinth
of tunnels,

Producing a never-before-seen
3-d model of the giant.

Mateusz uses innovative
laser scanners

To measure the dimensions of
the tunnels beneath the castle.

His aim... to understand exactly
what hitler is building here.

Mateusz's laser scanner
bounces light off

Static targets placed
throughout the tunnel system.

The refracted light
from the laser

Maps the surface of the rock.

Mateusz and colleague
aga ochalek

Think clues about
hitler's grand plan

Lie in the very rock
that surrounds them.

Harder than concrete,

Gneiss is a metamorphic rock,

Making it extremely difficult
to tunnel into.

But the nazis have come up
with a brutal solution

To their engineering problem...

Forced labor.

5,000 prisoners from nearby
concentration camp gross-rosen

Died digging these passages.

Forgotten victims
of hitler's obsession

To build bigger,
better, and stronger.

In the mobile lab,

The data from mateusz's scans

Is finally ready to process,

And the team makes
a fascinating discovery.

Not only are the tunnels
underneath ksiaz

Hollowed out from
incredibly strong rock,

Some of these tunnels
are also lined with concrete.

Mateusz's 3-d model uncovers

Mysterious concrete

But there's more.

Incredibly, the tunnels
beneath the castle

Are far more extensive than
they could ever have imagined.

Some of the super
bunker's tunnels

Run deep into the mountainside.

What is hitler building here?

The tunnels at ksiaz castle
are part of a much larger plan.

Hitler orders work on six other
underground sites nearby.

But what is their purpose?

Could they be part of a network
to protect the entire nazi elite

With ksiaz castle
hitler's centerpiece?

Or could the sites
be underground factories

That furnished the nazi
war machine with vehicles?

Could they even be part
of a top-secret plan

To develop nuclear weapons?

With the sites unfinished,
these mysteries remain unsolved.

The soviets advanced through
poland towards the giant.

If hitler can finish his network
of super bunkers,

He can try and hold out here.

But his plans fail.

The soviet advance pushes hitler
back from the giant.

He falls back to berlin
and his fuehrerbunker.

In this adapted air raid shelter

Never designed
as a headquarters,

Hitler is more vulnerable
than ever before.

How can he command his armies
and rule his reich from here?

Narrator: In the final months
of world war ii,

Hitler abandons
the eastern front.

He retreats from his forest
stronghold, the wolf's lair.

Then from his stunning
super bunker, the giant.

The advancing soviets
beat the nazis back to berlin

And hitler to his bunker.

Hitler's chancellery bunker.

It was the epicenter,
the nerve center,

The command and control center

For hitler's
nazi entire war machine.

Narrator: This parking lot

Less than a mile from
the brandenburg gate

Was once home
to the fuehrerbunker.

More than 70 years ago,

Germany's war effort
and hitler's survival

Depended on him
running the war from here.

This was where hitler played out
the final scenes

Of the second world war.

The last hundred days
of his life, he moved in here

And only briefly, twice,
did he ever come out again.

[ hitler speaking german ]

Narrator: Designed to be
occupied only in an emergency,

The fuehrerbunker is now
hitler's final life line.

A whirring engine room
generates electricity 24/7,

Powering three large filters

To clean the air pumped in
from aboveground

And huge pumps to drive out the
constant seepage of groundwater.

A communications room provides
two-way contact

With the outside world.

Facilities are basic,

And life down here
is damp and uncomfortable.

How is it possible
to wage a war from here?

Military historian nigel dunkley
wants to discover

How hitler commanded his armies
from his berlin bunker...

...Once nothing more than
an air raid shelter.

He believes this nazi-built
communications control center

On the edge of berlin
can offer clues.

Here we are deep underground,

In a place called
zossen wuensdorf,

And we are in the former command
bunker of the german wehrmacht,

Of the german armed forces.

This is the heart
of the commcen,

The communication center.

No sense in just having hitler
giving orders

Unless they can be communicated.

And one of the main ways
of communicating his orders

Is by this message system.

Narrator: In the fuehrerbunker,
all communications

Run through
a central communications room

With an ss sergeant
on duty at all times.

A telephone switchboard
gives hitler voice communication

With the outside world,

And calls can be routed
to his private office.

A telex machine gives
the fuehrer

Secure two-way
text communication

With his generals
in all corners of the reich.

And a large antenna
above the bunker

Connects to an army radio set,

Allowing hitler to monitor
enemy radio broadcasts.

This underground bunker complex
where we are

Was made by the same company

That made hitler's
own personal bunker.

Narrator: With hitler's
fuehrerbunker no more,

This bunker is one of
the last places in the world

That could offer a glimpse into
the final days of his empire.

Nigel searches for a space

With roughly the same dimensions
as hitler's quarters.

Dunkley: Wow. Look at this.
Can you smell it?

You smell damp.
You smell plaster.

Look at the state of the walls.
Amazing. Look at this.

Nothing has been
touched here for decades.

Narrator: Virtually unchanged
since the 1940s,

Nigel gets a glimpse
into a long-forgotten past.

Dunkley: Right, having
discovered this little room,

What I want to do
is just measure it.

Trusty little tape measure.

Well, look at this.

Nigel's search is over.

Dunkley: Amazing.
The same dimensions.

It's 14 feet,

So pretty well
exactly the same dimensions

As hitler's own private room.

I'm getting goose bumps
just thinking about it.

This has got exactly
the same atmosphere

That one would expect
in hitler's own bunker rooms

If they still existed.

This is as close
you're ever going to get.

In a room exactly like this,

Hitler faces the annihilation
of his reich.

Dunkley: I find it remarkable.
I find it actually bizarre

When you think
of the big decisions

That he was required to make

And he made them
in such a small little room.

Narrator: Far removed from
his forest command center,

The wolf's lair,

And the huge underground
super bunker the giant,

Hitler wages a world war
from a few rooms

In a tiny, oppressive
former air raid shelter.

[ bombs whistling, exploding ]

And he's losing.

Dunkley: This is just
full of ghosts, isn't it?

Just full of atmosphere.

This is such a dark,
creepy place.

He became even more effected
by the weird atmosphere

That there is down here.

He was losing touch
with reality,

Not for the first time
in his life,

And that's quite clear.

He was giving orders to units,
to formations,

To armies even
which no longer existed.

[ hitler speaking german ]

He's on a different world
down here.

Narrator: In April 1945,
russian troops enter berlin.

In his bunker,

Hitler orders every german
to fight to the death,

But he swallows
a cyanide capsule

And then shoots himself
in the head.

Hitler's bunker outlives him.

But what happens to it
after his death?

Narrator: In may of 1945,

Hitler is found dead among
the rubble of his berlin bunker.

And the soviets discover
the subterranean world

That has been his stronghold
for the last four months.

Soviet leader joseph stalin
orders its destruction.

But that's not
the end of the story.

In 1986,

Nearly 40 years
after stalin gave the order,

Robert conrad is driving
past the site

Now in communist east germany.

In the backyard of
the reich chancellery,

Workers unearth
something strange.

Intrigued, robert wants
to get a closer look.

He dresses up as a construction
worker to sneak into the site.

Robert has discovered
hitler's bunker.

Somehow, it has defied stalin's
orders for its destruction.

Robert returns several times
to photograph the bunker.

These are some of the final
photographs of hitler's bunker.

Shortly after these photos
are taken,

The east germans
begin to destroy it.

After two years,

All the east germans managed
to do is demolish the roof.

Unable to completely
destroy the bunker,

They build a parking lot
on top of it.

Despite all efforts,
the fuehrerbunker lives on.

From his frontline wolf's lair

To his giant super bunker
underneath a mountain,

Hitler is on a quest
for engineering perfection,

But these abandoned structures
are now

A monument to his downfall.

Spending the final days
of the war

In an adapted air raid shelter

Never intended
as a command center,

Hitler's berlin bunker
becomes his tomb.

A hidden reminder
of germany's violent past

And a thrilling
archeological window

Into a world few have ever seen.
