Secret German Tunnels from World War II Discovered! | Expedition Unknown

this tunnel carved through an extinct
volcano by the nazis has been
rediscovered after 80 years. this is
proof that the nazi map is real, but what
lies out of our camera’s field of view?
oh there is a tunnel.
look at that! wait, what is that?
it’s a what? it’s a minecart! it’s a
minecart? yes, one of the trucks. it’s a
huge tunnel! yeah.
look, just in and of itself this is an
absolutely astounding view.

sebastian leads me downhill where I
quickly realize the scale of his group’s
ambition.
wow!
cutting lumber.
this is— is this all part of the project?
yes, lumber and the steel and the machine.
wow, all to the project. and since
confirming the map is accurate, they have
worked non-stop three shifts a day just
to get where they are now.
spectacular undertaking!

get out of here!
oh!
my word! are you—
this is the tunnel? yes!
[Music]
oh my god, look at this place!
huge amounts of construction here.
hey sebastian, yes this is all new
construction? yes, you did all this?
so they had to build up all of this, all
of this that you see around us here.
okay.
there.
36 here, so the big tunnel with the
minecart is past this wall? yes, yes.
the wall consists of stones that have been
stacked floor to ceiling and extend deep
into the passage.

10 meters from here it will—it was all stacked like this on
purpose. 10 meters of stones, 10 liters
were a buffer. they don’t know exactly
why it was, but it was put there on purpose.
so for 30 feet there’s been stacked
stones being pulled out here? yes.
so whatever’s on the other side of this
wall was intentionally sealed behind 30
feet of rocks. I can’t think of anything
I’ve ever seen that was as well
protected.

okay, it’s like they can see through it.
until this point we only were there with
cameras, but today when we remove
the stones, we can actually enter. can I
see? yes!
oh!
yes, there is a tunnel!
ghost? yes, it is a ghost! oh yeah, look!
look, look, look! yeah,
yeah original and stay,
and it’s not collapsible, it’s
not collapsed yet.
yes, good news!
that is amazing!

everybody be very careful, guys.
this section of the tunnel is muddy and
flooded and the supports have been
soaking it all in for 80 years. the
threat of collapse is ever-present.
oh it’s very interesting. look at that,
here look at this.
it’s like a cross-section of this.
this is instructive. you know, they’ve got steel
beams. the roof is not finished, no, but it
is much more supported than the other
part of the tunnel. yeah, yes.

what’s above us is remarkable, but
nothing compared to what we find at our
feet.
look at this! so now
we have
railroad tracks, and these go all the way
to the entrance to the channel, yeah. and
we don’t know how far back we have
material, wood material, prepared too.
so are these— these are what? these are
beams that never got put up? yes.
so kind of, for example, there’s another
part.
look at this!
it’s so tall! pickaxe, look at this!
just literally left here leaning against
the wall.
how crazy is that?

[Music]
it’s actually kind of
kind of eerie because you can just
imagine a worker here just laying that
down. you know, I mean it’s like somebody
was just here.

despite how it looks, this tunnel wasn’t
a mine. all of this looks like they were
just in the middle of construction.
I’m also amazed just when you really see
without the wood,
what they were drilling through here. I
mean this must have been a huge amount
of effort. this is not like soft earth;
they’re drilling through basalt. I mean
that’s incredible!

it’s very possible that it was made by
prisoners, yeah exactly.
during world war ii, germany established
over 450 forced labor and extermination
camps inside poland as the nazis
implemented hitler’s final solution to
his so-called jewish problem.

some of their names— auschwitz, treblinka,
sobibor— are burned into history like a
brand, but others have been tragically
forgotten like the work camp here in the
town of lubon.
the tunnel I’m in now was likely a
product of some of that slave labor. it
is a literal scar in the countryside of
poland, one that time alone cannot fully
heal.

wow!
[Music]
we follow the rotting electrical cables
toward the mine cart we saw from the
surface until the tunnel widens in the
darkness.
oh!
my word! a big intersection here!
now it just opens up. there’s our mine
cart!
and we’ve got a four-way intersection
here.
we can go to here? yes! consume this place!
with this part here, this roof is very
dangerous.
the supports above have long rotted away,
making every second we spend here a
calculated risk.

I want to know
what’s in that mining cart. anything?
[Music]
carefully.
oh, look at this!
we got tools in here—
shovel,
and then a broken shovel head, another
shovel here, oh and there’s a second cart!
it looks like, uh, some accident because
this crashed.
right, they look like they’re kind of
like they hit each other. they’re piled
up.
this one is empty, this is empty,
and then
a kind of a turntable here for the carts
to go in different directions. can we
look at the map here for a second again?
let’s kind of get our bearings here. so
we are
here at this intersection here.
this is supposed to go a big straight
tunnel to the left.
it turns. yeah, why do you think it does
that? nobody knows!

in this moment,
for the first time, sebastian’s map, which
has guided him unerringly to this moment,
now proves to be inaccurate. the tunnels
don’t seem to go where they should be
going. deciding where to explore next,
sebastian nixes the offshoot to the
right since it appears to be in even
worse condition than our current path,
which leaves us with a left-hand turn.
so let’s see why this changes direction.
yeah.
there’s just
no protection above us here at all
and a billion pounds of
rock. okay, let’s see what’s around this
corner.
whoa!
[Music]
okay we got a dead end here.
looks unfinished.
look at these drill bits! wow!
and then a few more against the wall.
and then literally a drill bit! wow! right
at the end.

a big question is where’s the drill?
I think it was more expensive.
do you think they took it with them? yes!
it’s amazing though—it’s like they
literally just were here and then just
like said okay, that’s it, we’re leaving.
they were working till the end, right?
they really were! you can even see
in the wall it looks like where they
started to drill here. you can see that
the tunnel is going to continue here. the
drill bit they just took out of the end
of the drill dropped it on the ground
and that’s it.

in fact, just workers are missing from
this place. I mean, that’s—that’s it, right?
it really does! it makes it seem like
this was probably forced labor, right?
because
if there’s no personal items, maybe
there’s people here who have no personal
items.

[Music]
we’re here for only a moment when it
becomes clear that this dead end has a
potential to be our end as well. hey josh,
look at that!
oh, the crack!
it’s really dangerous.
and here as well, the way
