Fishburne: Tonight,

one of World War II's most enduring mysteries.

A stunning treasure worth half a billion dollars

lost without a trace.

- It might be the most expensive and beautiful

work of art ever made.

It's like it's just vanished.

Fishburne: Now, we uncover the top theories

surrounding the disappearance of a work of art so remarkable

that it's known as the eighth wonder of the world.

♪ ♪

- The castle suffers tremendous damage.

♪ ♪

You have to wonder,

was the Amber Room destroyed as well?

- Stenz and Mederer are convinced

that the Amber Room is hidden

behind the castle's walls just waiting to be explored

and waiting to produce discoveries.

Fishburne: Can a new expedition finally reveal its location?

- It's a treasure trove of material.

Fishburne: Will we ever be able to find

and incomparable Amber Room?

[dramatic music]

Fishburne: It's September, 1941.

Leningrad, USSR.

♪ ♪

Nazi forces invade Russia, moving relentlessly east

in a vicious sweep of destruction.

As his troops advance,

Hitler gives one important order:

preserve the priceless works of art

in Leningrad's Catherine Palace at all costs.

[soft dramatic music]

- Hitler wants to gut Russia,

and he wants to steal every work of art he can

en route to conquering the entire country.

The Catherine Palace supposedly houses

the most valuable work of art in the world.

♪ ♪

Fishburne: The artwork in question

is known as the Amber Room.

- It's exactly what it sounds like.

It's a room covered in beautiful amber panels.

Some people estimate it

to be worth over half a billion dollars,

making it one of the most expensive

and beautiful rooms ever created.

- During World War II, the German military stole

over 600,000 pieces of art from across Europe,

ransacking billions of dollars

worth of priceless cultural artifacts.

Fishburne: And some say

Hitler wants the Amber Room above all else.

- Not only does Hitler love art,

but he's also a nationalist,

and it infuriates him

that there are works of German art

outside of German territory,

and the Amber Room is a German work of art

that he desperately wants back.

Work began on the room in 1701 in Berlin,

which then was part of Prussia.

Fishburne: Frederic I, who rules over

the powerful empire in what's now Germany

originally commissions the Amber Room.

- Designed by a sculptor named Andreas Schluter,

and it's lavish and it's resplendent

and it's expensive and it's valuable.

♪ ♪

- Andreas Schluter starts by melting the amber

to the point where it is a thick kind of liquid.

At the time, Amber wasn't really used like this,

so in addition to being a beautiful work of art,

it's also enormously innovative.

♪ ♪

As if that isn't impressive enough,

then these 18th-century craftspeople

encrust them with jewels

and then cover it with gold and silver leaf.

It's also adorned with these four Italian mosaics,

making them works of art within a work of art.

King Frederic wants a palace

that will outshine France's Versailles,

and he decides that this is going to be the centerpiece.

Fishburne: In 1701, the Amber Room is installed

in the Berlin City Palace,

but it won't be there for long.

♪ ♪

- The Amber Room unsurprisingly

attracts the attention of another European royal,

Russia's famous tsar, Peter the Great.

Peter the Great visits the Berlin City Palace in 1716,

and he gets a tour of the Amber Room.

King Frederic is trying to forge an alliance

with Russia at the time, and he basically says,

"You want the Amber Room? You can have it."

♪ ♪

Around the time of Empress Catherine the Great,

it's installed in the Catherine Palace

and that's where it stays

undisturbed and unmoved for about two centuries,

and even after Russia becomes the USSR

and St. Petersburg becomes Leningrad,

the Amber Room is just there pretty peacefully

until the Nazis arrive.

- And here's where the mystery starts,

because after the Nazi siege of Leningrad,

the Amber Room goes missing.

Everything else is just theories.

♪ ♪

- We think that the Nazis do in fact

steal the Amber Room from Leningrad.

- The most valuable cultural institutions at the time

Fishburne: Hitler gives specific instructions

not to destroy the Catherine Palace,

- So there's this one room, pretty nondescript,

Fishburne: The room had been hidden

by head Soviet art curator Anatoly Kuchumov.

♪ ♪

- The original plan is for Kuchumov to pack up

as many works of art as possible for safekeeping,

and bring them deeper into Russia

and away from Nazi hands.

Kuchumov does an analysis of the Amber Room

and he realizes that these panels are very delicate

and they've become brittle over time,

so there's really only one move left to make.

Fishburne: Kuchumov covers the Amber Room

from floor to ceiling in thick wallpaper,

hoping the Nazis won't look too closely.

♪ ♪

- But in this last-ditch effort,

the Germans uncover the ruse.

And unlike Kuchumov,

they have all the hands and time that they need

to pack this thing up very carefully and slowly.

They spend about two days dismantling the Amber Room

and packing it into crates.

Fishburne: But where does the Amber Room go from here?

♪ ♪

- The Germans take the Amber Room

along with a number of other important

Russian cultural artifacts,

and transport them to Konigsberg Castle.

♪ ♪

- Hitler's ultimate plan is to build a museum,

the greatest museum in the entire world,

and it was going to be in his hometown

of Linz, Austria.

Eventually, the Amber Room would go there,

but while the museum was being built,

the Amber Room would wait in Konigsberg Castle.

Fishburne: On November 13th, 1941,

a local newspaper announces an exhibition

featuring the Amber Room at the castle.

- So that's the best evidence we have that the Amber Room

ever actually went to Konigsberg,

but we don't have any photographic evidence of that,

and so we're not really even sure if that ever happened.

- Now here's the really unfortunate part.

While we don't know what happened

to the Amber Room,

we do know what happened to Konigsberg Castle,

- But there at the castle among the wreckage,

there's only a small percentage of the Amber Room that's found.

This leaves some to wonder, "Really?"

"A whole room, and this is all that's left?

A room that took crates and crates to pack away?"

This has many theorists thinking,

"There's gotta be another explanation."

- What if the Germans moved the Amber Room

before the Soviet invasion of 1945?

- [speaking German]

- We have orders given by Adolf Hitler himself

on January 21st and January 24th, 1945.

[machine gun fire]

♪ ♪

The tide of war has changed.

He knows that Allied forces are moving in,

so he issues orders

that all looted material in Konigsberg Castle be moved.

Fishburne: Some speculate that a high-ranking Nazi commander

named Erich Koch

follows these orders.

- He was in charge of all civil administration,

including police and Gestapo operations

in East Prussia, Ukraine, and Belarus.

This is a territory that includes Konigsberg,

so anything that happens at Konigsberg Castle

is happening under his authority.

Fishburne: Then, in January 1945, Koch flees.

[soft dramatic music]

- Koch manages to stay on the run for four years

until he's captured by the British.

In 1950, he's returned to Poland

where he's forced to stand trial for war crimes,

at the end of which, he is sentenced to death.

- But here's the strange thing.

His death sentence is pretty quickly commuted

to life imprisonment.

Plenty of Nazis are executed for their war crimes.

There's no real reason for Koch to be spared.

His crimes are just as bad as any other Nazi,

and he's unrepentant about it.

He's truly a vile person.

♪ ♪

Fishburne: Is Koch spared

because he has valuable information?

- Koch's sentence is commuted

after a long period of interrogation

by Soviet authorities,

and we think that during this interrogation,

Koch reveals that the Amber Room has survived...

and he knows where it is.

♪ ♪

- According to Erich Koch, Adolf Hitler ordered

that the Amber Room be packed up and moved

in January 1945.

He reveals that they packed it up

into 24 wooden crates

and trucked it 60 miles from Konigsberg

to a more fortified Nazi stronghold

at Mamerki, Poland.

Keep in mind that throughout this interrogation,

he continues to badmouth the Jews and the Soviets,

and he's also singing the praises

of Hitler and the Nazis.

It's not like he was trying to tell the Soviets

what they wanted to hear.

That lends a credibility,

that makes this more of a believable possibility.

♪ ♪

- This is also a testament to just how important

the Amber Room is to the Soviets,

that they're gonna spare a top Nazi

in exchange for a tip, basically,

just to keep the hope alive of recovering the Amber Room.

♪ ♪

Fishburne: But when the Red Army

arrives in Mamerki in the 1950s,

they meet an incredible challenge.

♪ ♪

- Mamerki was the center of the German command

on the Eastern Front and it was a massive complex,

and Mamerki hides a few secrets itself.

- Above ground,

the Germans build about 200 buildings,

and the entire fort covers about 600 acres.

But guess what?

Underneath the ground is even more impressive.

There are miles and miles

of underground bunkers and tunnels.

♪ ♪

- It's a hidden maze

and that's because of the fact that

during the course of the war, the Nazis backfill,

they fill in some of the tunnels

that they had built earlier in the conflict.

Then with the passage of time, Mother Nature works her magic,

making this underground complex

an extraordinarily difficult place to search.

♪ ♪

Fishburne: The Russians spend years

searching Mamerki with no results.

♪ ♪

- So after two decades of searching,

the Soviets are so desperate,

they take Koch out of prison in 1970

and bring him to Mamerki to try to find the Amber Room.

He points at a particular bunker

where he thinks the Amber Room was taken,

but it's not there.

- To that, you could say

that maybe Erich Koch's memory had lapsed,

or he's just trying to survive.

Because after all,

if the Soviets do find the Amber Room,

they have no more reason to keep Erich Koch alive.

Playing the Soviets the way that he did,

Erich Koch manages to stay alive

for almost another 20 years

until he dies of natural causes in 1986 at age 90.

♪ ♪

Fishburne: Even so, the search for the Amber Room continues.

- These days, Mamerki is overgrown and falling apart,

but parts of it are run as a museum

by a Polish man named Bartek Plebanczyk,

and he fully believes

that the Amber Room is still there.

- They even have a replica of the Amber Room

inside of the museum, and every year,

Bartek excavates a different bunker in Mamerki.

That's all he could afford to do, one a year,

but he's gonna keep going until he finds the Amber Room.

- So far, they have found tons

of Nazi and Soviet artifacts, but it's estimated

that only 1% of the entire compound has been searched,

and that means that there could be

tunnels and bunkers still in that complex

just waiting to be explored

and waiting to produce discoveries.

These tunnels and chambers

have been unexplored in over 70 years,

We have a lot of good equipment,

we have underwater drone, we have multibeam.

we have sonars, and we have ten very well-trained divers.

This is, like, amazing moment in the history.

Fishburne: It's June 2020,

is heading into the Baltic Sea on a treasure hunt.

[soft dramatic music]

Its mission?

Locate the wreck of the torpedoed Nazi steamer

SS "Karlsruhe" and see if the Amber Room's on board.

♪ ♪

- We don't know exactly what we can expect on the bottom.

Maybe the current will be huge,

maybe the visibility will be close to zero,

or the wreck would be covered by nets.

All of them are very dangerous,

so we must be prepared for all condition.

♪ ♪

- For 75 years, no one has seen this ship.

It's just been lost, but we know that it carried

hundreds of tons of Nazi goods.

So could the Amber Room be among them?

Fishburne: As the divers descend to 288 feet,

the search conditions grow more challenging.

♪ ♪

- In a safe way, we have to use a lot of equipment.

We have to use very high-quality dry suit.

Special underwater heating system.

We have to survive more like three hours underwater.

We have 300 feets of cold, dark water.

It's not easy dive,

and we have to do it in a very, very safe way.

We saw that the beautiful wreck,

if you can say about the wreck beautiful.

I have never seen so many artifacts,

Fishburne: But what about the Amber Room?

Beneath a large pile of debris,

the divers make out what appear to be

dozens of sealed crates.

- Now that's the most interesting thing, of course.

Here we have crates

that match the description of the Amber Room.

Of course, they might just contain ammunition

or silverware, sundries.

But what if?

♪ ♪

Fishburne: Unfortunately,

the team is unable to safely transport the crates.

They'll have to return with additional equipment.

♪ ♪

- So unfortunately, they can't search the crates

on this trip.

At those depths,

you only have about 30 minutes max down there.

The last thing they want to do

is potentially damage the Amber Room in the process.

♪ ♪

- This expedition is step number one:

to identify the wreck, to check what is this,

but definitely we need expedition number two

when we can check exactly what cargo contain.

♪ ♪

Fishburne: Plans are moving forward

for a salvage and recovery mission

in the next few months.

♪ ♪

- To check cargo on the "Karlsruhe,"

we need to do it on the proper way.

On the proper way that means that we have to spend days

or even weeks on the position,

that we have to anchor permanently the boat

with special equipment for the divers.

♪ ♪

- This time, they'll be bringing many more resources

to the effort.

They'll have divers that can work on a rotating basis,

they'll have equipment that can float large objects.

If they find a crate,

they'll need to leave it sealed

until they get it to the surface.

from the National Maritime Museum in Gdansk, Poland

as an advisor.

- It's a once-in-a-lifetime opportunity

to bring something as rare and as valuable

a cultural resource as the Amber Room to the surface.

♪ ♪

This is a mystery on par with the Dead Sea Scrolls

and the discovery of King Tut's tomb.

Is it down there? I don't know.

But I certainly hope it is,

because I would love to see this thing finally revealed.

I would love to see this mystery solved.

♪ ♪

- I couldn't imagine how would we feel

when we find hard proof on the "Karlsruhe" ship

that we find Amber Room.

This is absolutely out of my imagination,

but perhaps it will be something special and unique

and maybe I remember this moment

till to end of my life.

♪ ♪

- Could the Amber Room lie in crates

at the bottom of the Baltic Sea?

If the dive team is successful

and can salvage what's aboard the SS "Karlsruhe,"

we may soon know the answer to this enduring mystery.
