0:00:05 > 0:00:08I've come to this remote corner of southern Poland
0:00:08 > 0:00:11to try to unravel one of the last great mysteries
0:00:11 > 0:00:12of the Second World War.
0:00:13 > 0:00:16It's a story that's attracted the world's media.
0:00:16 > 0:00:19Two men say they know the exact location
0:00:19 > 0:00:20of the Nazi ghost train...
0:00:20 > 0:00:23..That went missing in 1945.
0:00:23 > 0:00:24This is an extraordinary story.
0:00:24 > 0:00:27It's captured the imagination of many who live here,
0:00:27 > 0:00:28even including
0:00:28 > 0:00:30members of the Polish government.
0:00:34 > 0:00:36I'm hunting for a secret tunnel...
0:00:36 > 0:00:39Whoa! It's on a big scale, isn't it?
0:00:39 > 0:00:42..that local legend says was hidden by the Nazis,
0:00:42 > 0:00:45and in it, a lost train said to be laden with gold.
0:00:45 > 0:00:47And do you think this is where
0:00:47 > 0:00:50the rumours of this gold train comes from?
0:00:50 > 0:00:54I'll consider the evidence that treasure might be hidden here.
0:00:54 > 0:00:55An area that, for much of the war,
0:00:55 > 0:00:58was considered the safest place in Nazi Germany.
0:01:05 > 0:01:07I'll follow the treasure hunters
0:01:07 > 0:01:09who've spent years searching for the train,
0:01:09 > 0:01:11and may now be about to find something.
0:01:14 > 0:01:16I'll delve into the region's past...
0:01:16 > 0:01:20This feels like you're entering the dark heart of the Nazi world.
0:01:20 > 0:01:25..revealing a high-level plan to build a top-secret Nazi HQ
0:01:25 > 0:01:27in this remote corner of the Third Reich.
0:01:29 > 0:01:32This extraordinary tale features a hilltop castle
0:01:32 > 0:01:35converted into a bolthole for Adolf Hitler
0:01:35 > 0:01:37in the final months of the war...
0:01:37 > 0:01:41- This room now was going to be Hitler's bedroom?- Yes, exactly.
0:01:42 > 0:01:45..and a mysterious network of tunnels
0:01:45 > 0:01:48dug out of the ground by slave labourers.
0:01:48 > 0:01:51This was going to be an industrial underground city.
0:01:52 > 0:01:56If Hitler was planning to retreat to this remote part of his empire,
0:01:56 > 0:02:00then could Nazi gold have ended up here, too?
0:02:01 > 0:02:05If it's true, it's the kind of thing that happens once in a lifetime.
0:02:05 > 0:02:08A secret underground Nazi train
0:02:08 > 0:02:11loaded with valuables, buried for decades,
0:02:11 > 0:02:14local people who were silenced first by the Nazis, then by the Soviets,
0:02:14 > 0:02:18finally coming out and telling their stories.
0:02:18 > 0:02:21It's the kind of thing us history lovers dream about.
0:02:43 > 0:02:46I've arrived in the outskirts of Walbrzych,
0:02:46 > 0:02:51a former mining town in southern Poland, where for many locals,
0:02:51 > 0:02:53treasure hunting has become an obsession.
0:02:57 > 0:02:59I've arranged to meet Wojtek Malinowski,
0:02:59 > 0:03:02a film-maker who grew up here
0:03:02 > 0:03:04and who's been following the story for years.
0:03:06 > 0:03:09- How are you doing? Nice to meet you, Wojtek.- Nice to meet you.
0:03:09 > 0:03:12A very beautiful place. WOJTEK CHUCKLES
0:03:12 > 0:03:14If you think it's beautiful.
0:03:14 > 0:03:17I'm hoping he'll show me the tunnel that's been making headline news
0:03:17 > 0:03:18all over the world.
0:03:18 > 0:03:20Come on, follow me.
0:03:20 > 0:03:24But instead, he takes me to a non-descript piece of land
0:03:24 > 0:03:27at a location known simply as Kilometre 65.
0:03:28 > 0:03:30So what are we looking at here?
0:03:30 > 0:03:34This area looks strange. What do you think?
0:03:34 > 0:03:36This part of this area?
0:03:36 > 0:03:38Yeah, there's steep banks here,
0:03:38 > 0:03:40and then there's a sort of bowl there.
0:03:40 > 0:03:44And some people think that it was...
0:03:44 > 0:03:48a little part of this railway which connects to the tunnel,
0:03:48 > 0:03:51which probably will be there.
0:03:51 > 0:03:53All the rest of those banks
0:03:53 > 0:03:55look like they follow the original railway line,
0:03:55 > 0:03:56and yet here, there's this bowl.
0:03:57 > 0:04:01Wojtek takes me to the K65 milestone,
0:04:01 > 0:04:04where the entrance to the secret tunnel is believed to be.
0:04:04 > 0:04:06Ah! What's this?
0:04:23 > 0:04:24That is interesting.
0:04:24 > 0:04:27I mean, it doesn't look anything like a railway tunnel.
0:04:27 > 0:04:29Why do you think this is the area, particularly,
0:04:29 > 0:04:32that the Germans camouflaged at the end of the war?
0:04:44 > 0:04:46You're right. On the other side, over here, and...
0:04:46 > 0:04:49- Yes, yes.- ..elsewhere, there are much older trees.
0:04:58 > 0:05:02About 400 metres further along the same railway embankment,
0:05:02 > 0:05:05Wojtek wants to show me two mysterious structures
0:05:05 > 0:05:08which he thinks prove the Nazis were at work here.
0:05:09 > 0:05:11So you think there's a tunnel underneath us now?
0:05:11 > 0:05:14Yes. I hope.
0:05:14 > 0:05:15You hope!
0:05:17 > 0:05:19What are these?
0:05:47 > 0:05:50No way. Ventilation shafts?
0:05:50 > 0:05:51- Of course.- Yes.
0:05:53 > 0:05:56Wojtek isn't alone in his suspicions.
0:05:58 > 0:06:02Local treasure hunters have been scouring this area for decades.
0:06:02 > 0:06:04This is because in 1945,
0:06:04 > 0:06:07the town of Walbrzych and the whole of Lower Silesia
0:06:07 > 0:06:10were not part of Poland, but Germany.
0:06:10 > 0:06:13It was also beyond the range of the Allied bombing campaigns
0:06:13 > 0:06:16that targeted the country from 1942.
0:06:16 > 0:06:19And so, rumour has it, many important documents, artworks,
0:06:19 > 0:06:22even gold, were buried in the mountains.
0:06:22 > 0:06:25But I'm after something more substantial than rumours.
0:06:25 > 0:06:29I need firmer evidence before I can even start to believe
0:06:29 > 0:06:32that there might be a secret Nazi railway tunnel
0:06:32 > 0:06:33on the outskirts of this town.
0:06:36 > 0:06:38What I really want is a first-hand account.
0:06:38 > 0:06:42I'd love to hear from somebody who actually saw the railway,
0:06:42 > 0:06:45the siding and the tunnel during the war with their own eyes.
0:06:45 > 0:06:47There is one man who may be able to help.
0:06:47 > 0:06:51His name is Tadeusz Slowikowski, he's a retired miner, and it was him
0:06:51 > 0:06:55who first identified the great potential at this particular site.
0:06:55 > 0:07:01He's spent the last two decades looking for Nazi loot.
0:07:01 > 0:07:03Hi, Tadeusz. Dzien dobry.
0:07:05 > 0:07:09- Dzien dobry.- Dzien dobry! Dzien dobry!- I'm Dan.
0:07:09 > 0:07:12Tadeusz Slowikowski is one of the last men alive
0:07:12 > 0:07:14to have spoken to Germans who claim that during the war,
0:07:14 > 0:07:18they saw a second train track at Kilometre 65.
0:07:18 > 0:07:21Ah, your man cave, Tadeusz.
0:07:21 > 0:07:23He first heard about the mysterious tunnel
0:07:23 > 0:07:25from an engine driver's assistant
0:07:25 > 0:07:28who regularly travelled along the railway line.
0:07:28 > 0:07:32He's even built a replica of the site as it's been described to him,
0:07:32 > 0:07:33in his garage.
0:07:37 > 0:07:41So, here we go. This is the model of the tunnel and the siding.
0:07:41 > 0:07:43- And this is Kilometre 65 here?- Tak.
0:07:43 > 0:07:47So you've talked to an engine driver on this mainline
0:07:47 > 0:07:49who saw two carriages here in the siding?
0:08:08 > 0:08:11Tadeusz tells me that he's spoken to other locals
0:08:11 > 0:08:13who confirm the train driver's account.
0:08:13 > 0:08:16Like him, they also claim to have seen military trains
0:08:16 > 0:08:20on a hidden track running off the mainline into a tunnel.
0:08:20 > 0:08:23It's great to see a visualisation of Tadeusz's theory,
0:08:23 > 0:08:25it's not all just words any more.
0:08:25 > 0:08:27You can actually see it laid out.
0:08:27 > 0:08:29And if what he says is true,
0:08:29 > 0:08:32high walls would have prevented anyone using that mainline
0:08:32 > 0:08:34from looking into these sidings here,
0:08:34 > 0:08:36with the exception of that one guy,
0:08:36 > 0:08:40that enterprising guy, who stood up on the coal behind his locomotive
0:08:40 > 0:08:43and peered over and saw this siding.
0:08:43 > 0:08:45And there's the tunnel.
0:08:45 > 0:08:46And we have seen some...
0:08:46 > 0:08:49possibly some of the stones from that tunnel at the site.
0:08:51 > 0:08:53Looking at this, what really strikes me
0:08:53 > 0:08:55is why did the Germans go to all this trouble
0:08:55 > 0:08:57to make sure that this little siding
0:08:57 > 0:09:01and the tunnel it was connected to remain secret?
0:09:01 > 0:09:04There must have been something pretty important down there.
0:09:08 > 0:09:10After speaking to Wojtek and Tadeusz,
0:09:10 > 0:09:12a picture is starting to appear.
0:09:12 > 0:09:14A collapsed tunnel entrance,
0:09:14 > 0:09:18possible ventilation shafts emerging from the ground,
0:09:18 > 0:09:19Second World War accounts
0:09:19 > 0:09:23of a secret railway line hidden from view by the Germans.
0:09:23 > 0:09:26It's tantalising, if circumstantial evidence.
0:09:26 > 0:09:30But it's been enough for some locals to have gone one stage further.
0:09:30 > 0:09:35In 2014, local historian Andreas Richter and builder Piotr Koper
0:09:35 > 0:09:39decided to scan the area with ground penetrating radar,
0:09:39 > 0:09:42and they've agreed to show me what they found.
0:09:42 > 0:09:45Andreas, let's see some of the surveys from this area, then.
0:09:45 > 0:09:47Let's have a look at the tunnel and the train.
0:10:03 > 0:10:05What the radar technology revealed
0:10:05 > 0:10:09convinced them there really was something unusual at the site.
0:10:27 > 0:10:30So you're saying that... There's a sort of central stripe there.
0:10:30 > 0:10:33You're saying that's an unnatural, that's a man-made feature?
0:10:50 > 0:10:53HE SPEAKS POLISH
0:11:24 > 0:11:27That's the side of the tunnel? That's the wall of the tunnel?
0:11:27 > 0:11:29It's reaching up higher than what's in between it,
0:11:29 > 0:11:34and in between it, there appears to be a man-made, symmetrical object,
0:11:34 > 0:11:37a big, substantial object, like it's a train with an engine.
0:11:55 > 0:11:57The images are very seductive.
0:11:58 > 0:12:01But are the treasure hunters seeing what they want to believe?
0:12:02 > 0:12:05They don't claim the train is full of treasure,
0:12:05 > 0:12:08but there could be a great deal of money in this for them
0:12:08 > 0:12:09if they really have struck gold.
0:12:13 > 0:12:16Well, you can't help but be carried away by their enthusiasm,
0:12:16 > 0:12:20but I did leave there slightly questioning their motivation.
0:12:20 > 0:12:21What was really driving them on?
0:12:21 > 0:12:23A great love of history and archaeology?
0:12:23 > 0:12:28Or the desire to get their hands on that Nazi gold?
0:12:28 > 0:12:32They're claiming a 10% finder's fee and they have employed a lawyer,
0:12:32 > 0:12:34so they must believe they're onto something.
0:12:38 > 0:12:40So what is it about this part of Poland
0:12:40 > 0:12:42that's caused so much speculation?
0:12:45 > 0:12:47That's what I need to find out next.
0:12:50 > 0:12:51For much of the war,
0:12:51 > 0:12:54this south-eastern corner of the Third Reich
0:12:54 > 0:12:56was far away from the front lines...
0:13:00 > 0:13:03..and out of range of the Allied bombing campaigns
0:13:03 > 0:13:05that from 1942
0:13:05 > 0:13:08started to lay waste to the country's industrial heartlands.
0:13:10 > 0:13:12The regions that fed the German war machine.
0:13:15 > 0:13:17Factories were relocated here
0:13:17 > 0:13:20and precious works of art were stored away for safekeeping.
0:13:27 > 0:13:29And beneath these mountains,
0:13:29 > 0:13:32they developed one of the most incredible schemes.
0:13:36 > 0:13:40A project so extraordinary, it defies imagination.
0:13:46 > 0:13:51There's a reason why the reports of a secret tunnel at Kilometre 65
0:13:51 > 0:13:53haven't just been dismissed out of hand
0:13:53 > 0:13:57and Piotr and Andreas derided as a pair of hopeful amateurs,
0:13:57 > 0:13:59and that is to do with its particular location.
0:13:59 > 0:14:03It isn't just a random railway siding in the middle of Poland.
0:14:03 > 0:14:09It sits right next to one of the most extraordinary and sinister
0:14:09 > 0:14:11Nazi projects of them all.
0:14:11 > 0:14:16A huge, secret underground labyrinth of tunnels
0:14:16 > 0:14:19burrowed out in the final years of the war.
0:14:19 > 0:14:22Its codename was Riese.
0:14:22 > 0:14:23Giant.
0:14:28 > 0:14:33This top-secret project started in 1943.
0:14:33 > 0:14:36Hitler entrusted the work to his favourite architect,
0:14:36 > 0:14:39Albert Speer, and his most skilled and trusted engineers,
0:14:39 > 0:14:41Organisation Todt.
0:14:41 > 0:14:45This organisation was responsible for major construction projects.
0:14:46 > 0:14:49The autobahns in the '30s...
0:14:50 > 0:14:52..the Siegfried Line,
0:14:52 > 0:14:54the Reich's western defences,
0:14:54 > 0:14:57and the construction of the Atlantic Wall
0:14:57 > 0:14:59along the western coastline of Occupied Europe.
0:15:01 > 0:15:04But now they were tasked with something even more ambitious.
0:15:08 > 0:15:10I want to find out what the Riese project was about
0:15:10 > 0:15:14in the hope it might shed some light on why so many people believe
0:15:14 > 0:15:16there's a hidden Nazi train in this area.
0:15:23 > 0:15:24Ah.
0:15:27 > 0:15:29Whoa!
0:15:29 > 0:15:31A narrow bit there.
0:15:33 > 0:15:35It's soaking wet in here.
0:15:48 > 0:15:53I've heard about people entering the dark heart of the Nazi world before.
0:15:53 > 0:15:56This feels like you're doing it literally.
0:16:04 > 0:16:06Local historian Lukasz Kazek
0:16:06 > 0:16:08has agreed to guide me through the Riese.
0:16:09 > 0:16:13We've come maybe 800 metres into the mountain here.
0:16:13 > 0:16:14How long are these tunnels?
0:16:20 > 0:16:23I can see there's tunnels moving off in all directions.
0:16:33 > 0:16:37Is this a natural cavern that they've just hit into?
0:16:50 > 0:16:53What were they doing down here? What was the point of this complex?
0:17:10 > 0:17:12And so you think this was going to be a huge...
0:17:12 > 0:17:14almost an industrial underground city?
0:17:28 > 0:17:33Lukasz tells me that many Riese tunnels have yet to be discovered,
0:17:33 > 0:17:35while other explorers have claimed that the Nazis hid treasure
0:17:35 > 0:17:38and top-secret weapons here in the last days of the war.
0:17:41 > 0:17:44All this seems to strengthen the case for the possible existence
0:17:44 > 0:17:48of another secret tunnel at nearby K65.
0:17:52 > 0:17:55The Nazis did complete other projects like this,
0:17:55 > 0:17:57like the vast underground factories
0:17:57 > 0:17:59discovered in central Germany after the war,
0:17:59 > 0:18:03where military aircraft and advanced rockets like the V2
0:18:03 > 0:18:04were being manufactured.
0:18:06 > 0:18:09But if the Riese project had been finished,
0:18:09 > 0:18:11it would have been even bigger.
0:18:11 > 0:18:13Could Hitler have been planning to develop
0:18:13 > 0:18:15even more deadly weapons down here?
0:18:17 > 0:18:18It was surprising me
0:18:18 > 0:18:20how much moisture was coming into the tunnels back there.
0:18:20 > 0:18:23Some sections of the tunnel have completely flooded.
0:18:24 > 0:18:27You have to get along hauling yourself on a rope.
0:18:30 > 0:18:33It's just otherworldly.
0:18:37 > 0:18:38Totally silent.
0:18:45 > 0:18:47Whatever the Riese tunnels were intended for...
0:18:50 > 0:18:52..there is no doubting their impressive scale.
0:19:04 > 0:19:07This is the biggest space I've seen down here by far.
0:19:10 > 0:19:12It's probably three storeys high.
0:19:14 > 0:19:16100 metres long, at least.
0:19:16 > 0:19:18It's vast.
0:19:18 > 0:19:21It's like an underground cathedral.
0:19:25 > 0:19:29It's not surprising that the people who came after,
0:19:29 > 0:19:31the Poles who arrived in this area,
0:19:31 > 0:19:36when confronted with these ghostly, echoing, half-built monuments...
0:19:38 > 0:19:40..made up stories, made up legends.
0:19:41 > 0:19:45These caverns have bred a whole generation of conspiracy theories.
0:19:47 > 0:19:50Some say the Riese complex was even designed
0:19:50 > 0:19:53to house the German atom bomb that the Nazis were developing.
0:19:54 > 0:19:58But whatever its purpose, one thing that's certain
0:19:58 > 0:20:02is that these tunnels came at an incredible human cost.
0:20:02 > 0:20:06It's estimated that 5,000 people subjected to forced labour
0:20:06 > 0:20:07died on the project,
0:20:07 > 0:20:11hacking out granite rock in temperatures just above freezing.
0:20:15 > 0:20:18For the thousands of innocent people worked to death here,
0:20:18 > 0:20:21Project Riese was simply a giant tomb.
0:20:32 > 0:20:35I'm going to Gross-Rosen concentration camp.
0:20:36 > 0:20:38It would have supplied the slave labourers
0:20:38 > 0:20:41for the excavation work carried out underground.
0:20:44 > 0:20:48Over the entrance is the great Nazi lie - "work sets you free".
0:20:52 > 0:20:56Emaciated prisoners like these carried out the backbreaking work.
0:21:00 > 0:21:04Local expert Marta Sadlocha has studied the living hell
0:21:04 > 0:21:06that was Camp Gross-Rosen.
0:21:08 > 0:21:10Most of the military industry
0:21:10 > 0:21:13was focused in the hands of forced labourers
0:21:13 > 0:21:15or prisoners of concentration camps,
0:21:15 > 0:21:17and in the case of camps like this,
0:21:17 > 0:21:19the work was a means to kill them all,
0:21:19 > 0:21:22so extermination was, of course, fulfilled in here.
0:21:23 > 0:21:25Of all the Nazi labour camps,
0:21:25 > 0:21:28the ones at Riese had the harshest living conditions
0:21:28 > 0:21:31and some of the highest mortality rates.
0:21:32 > 0:21:35The average life span was two or three months for one person,
0:21:35 > 0:21:38and this is how long they actually could live,
0:21:38 > 0:21:40especially when they worked as physically as here.
0:21:40 > 0:21:43So was Riese seen as a particularly brutal way to finish prisoners off?
0:21:43 > 0:21:46- That's why they sent the Jewish prisoners there?- Definitely.
0:21:46 > 0:21:48People had to work underground
0:21:48 > 0:21:54and even when the walls were exploded in some parts,
0:21:54 > 0:21:57they were sometimes not released to the surface,
0:21:57 > 0:21:59so they still had to work in the dust
0:21:59 > 0:22:03and various different toxic fumes out of the explosive substances
0:22:03 > 0:22:06so, yeah, they were ending even quicker than here.
0:22:08 > 0:22:12With death tolls rising, and the Soviets advancing,
0:22:12 > 0:22:16what must have been going through the minds of the men in charge here?
0:22:18 > 0:22:22Well, the last couple of days at the Riese and the Gross-Rosen camp
0:22:22 > 0:22:26have just driven home the sheer insanity
0:22:26 > 0:22:29of what the Nazis were doing in this region.
0:22:29 > 0:22:33I mean, the inhumanity and barbarism of that camp.
0:22:33 > 0:22:35But also, underlining that,
0:22:35 > 0:22:39the stupidity of murdering your own workforce when, allegedly,
0:22:39 > 0:22:41they were working on this enormously important, grandiose project,
0:22:41 > 0:22:46which actually just seems to me to be a totally insane folly,
0:22:46 > 0:22:49its purpose, still to this day, a mystery.
0:22:52 > 0:22:54I want to find out what else was going on in this region
0:22:54 > 0:22:57that might help to explain why a Nazi gold train
0:22:57 > 0:22:59could have ended up here, too.
0:23:01 > 0:23:04This is Ksiaz Castle,
0:23:04 > 0:23:09the largest and most stunning palace in the whole of Lower Silesia.
0:23:13 > 0:23:17The site of the suspected tunnel is less than two miles away.
0:23:21 > 0:23:25I've come here, as I've heard that there is a link between the castle,
0:23:25 > 0:23:29the Riese tunnels and the mystery at K65,
0:23:29 > 0:23:33and that Hitler himself may lie at the heart of the connection.
0:23:41 > 0:23:43- Hi there.- Welcome to Ksiaz Castle.
0:23:43 > 0:23:45Thank you. It's more like a palace that a castle.
0:23:45 > 0:23:47It is a palace AND a castle.
0:23:48 > 0:23:52Mateusz Mykytyszyn has studied the history of the castle.
0:23:52 > 0:23:58Since 1509 until 1933, it belongs to Counts of Hochbergs.
0:23:58 > 0:23:59Mateusz tells me
0:23:59 > 0:24:02how the Nazis confiscated the castle from its owners
0:24:02 > 0:24:07and planned to make it the centre of their operations in this area.
0:24:12 > 0:24:16Let me show you this interesting thing.
0:24:16 > 0:24:18This is a very different feel, isn't it?
0:24:18 > 0:24:21This is actual Nazi work. This is the guard room.
0:24:21 > 0:24:23The room that they were preparing
0:24:23 > 0:24:28for protecting important people that were staying here in the castle,
0:24:28 > 0:24:31and it was actually an escape room
0:24:31 > 0:24:33for elevators, for shafts, that they are here.
0:24:33 > 0:24:35So shafts leading where?
0:24:35 > 0:24:38Leading under the ground, into the tunnels.
0:24:38 > 0:24:41So there's a whole network of tunnels under the castle?
0:24:41 > 0:24:44At least two levels. Some people say more.
0:24:44 > 0:24:48We know right now for sure that there are at least two levels
0:24:48 > 0:24:53of over 1,400 square metres underground tunnel,
0:24:53 > 0:24:55covered with concrete in 75%.
0:24:55 > 0:24:58So that's why this place is talked about as part of the Riese complex,
0:24:58 > 0:25:01- because they tunnelled here as well.- Exactly.
0:25:02 > 0:25:05Let me show you the shaft that is still here
0:25:05 > 0:25:09and that was one of the evacuation elevators,
0:25:09 > 0:25:13so you could escape very easily to the underground.
0:25:16 > 0:25:17I've been to the rest of the Riese,
0:25:17 > 0:25:20it was for factories and for underground armaments.
0:25:20 > 0:25:23Why incorporate this palace?
0:25:23 > 0:25:26We believe it's supposed to be a headquarters
0:25:26 > 0:25:29for very important people from the German Reich.
0:25:29 > 0:25:31So who was supposed to come here?
0:25:31 > 0:25:32Very important person,
0:25:32 > 0:25:35I think the most important in the German Reich at that time -
0:25:35 > 0:25:36Adolf Hitler.
0:25:42 > 0:25:44Mateusz tells me
0:25:44 > 0:25:47that work to convert the castle began in mid-1944.
0:25:47 > 0:25:49INAUDIBLE
0:25:52 > 0:25:55The plan was to make it suitable for the Nazi High Command.
0:25:59 > 0:26:02At the same time as many thousands of German soldiers
0:26:02 > 0:26:04were losing their lives on the Eastern Front,
0:26:04 > 0:26:08no expense was spared as the Nazis redecorated the castle.
0:26:12 > 0:26:16The beautiful green and red rooms were painted white,
0:26:16 > 0:26:18its baroque and rococo features ripped out
0:26:18 > 0:26:22and replaced with the Nazis' favourite neoclassical style,
0:26:22 > 0:26:26making room for the greatest works of art looted from across Europe.
0:26:33 > 0:26:36It's amazing how much the Nazis managed to reshape this.
0:26:36 > 0:26:39They only had a year. It must have been a huge effort they put in.
0:26:39 > 0:26:42Not even a year. Ten months.
0:26:42 > 0:26:45And 25 young architects
0:26:45 > 0:26:51were working here on preparing this splendid residence,
0:26:51 > 0:26:54known as the Pearl of Silesia,
0:26:54 > 0:26:57to the grandest residence of Adolf Hitler.
0:26:57 > 0:27:02And that was the room that was prepared for him as his bedroom.
0:27:02 > 0:27:05- This room now...- Yes.- ..was going to be Hitler's bedroom?- Yes.
0:27:05 > 0:27:08Exactly. And that's why these two...
0:27:08 > 0:27:12doors were created, two pearl doors, to lead to his bathroom,
0:27:12 > 0:27:16but not only bedroom, but also his private lift
0:27:16 > 0:27:18leading to the tunnels under the ground.
0:27:18 > 0:27:21So, just outside the doors of his bedroom, he had a lift,
0:27:21 > 0:27:23so if there was an air raid or something,
0:27:23 > 0:27:26he could just get straight in and go down to the tunnels.
0:27:26 > 0:27:28The Riese mystery just grows larger and larger
0:27:28 > 0:27:30every time I learn more about it.
0:27:30 > 0:27:34And there is so many more mysteries to actually uncover here.
0:27:38 > 0:27:42Clearly, what Hitler had in mind here was a new command centre.
0:27:44 > 0:27:46By the time the Nazis took over this castle,
0:27:46 > 0:27:48the war in the East was going badly
0:27:48 > 0:27:50and the Soviet Red Army was advancing.
0:27:50 > 0:27:52Hitler seems to have responded to that
0:27:52 > 0:27:55by doubling down on the war effort, prepare himself and his empire
0:27:55 > 0:27:58for a war of annihilation against the Soviet Union.
0:27:58 > 0:28:02He had the vast Riese complex constructed in this area,
0:28:02 > 0:28:05kilometres of tunnels perhaps designed to be
0:28:05 > 0:28:08top-secret weapons production facilities.
0:28:10 > 0:28:13The new Fuhrer HQ was to be linked to the Riese complex,
0:28:13 > 0:28:16creating a subterranean shelter
0:28:16 > 0:28:19for 27,000 top Nazi and SS personnel,
0:28:19 > 0:28:22spread across 25 kilometres.
0:28:24 > 0:28:26The resources this project consumed
0:28:26 > 0:28:28were a massive drain on the war effort,
0:28:28 > 0:28:31something the Nazis could ill afford at this time.
0:28:35 > 0:28:37Albert Speer, who was Hitler's chief architect
0:28:37 > 0:28:40and weapons production minister,
0:28:40 > 0:28:42said that what was going on in this region
0:28:42 > 0:28:45sucked in more concrete, more materials,
0:28:45 > 0:28:48than the construction of every single air-raid shelter
0:28:48 > 0:28:49right across the Third Reich,
0:28:49 > 0:28:52so this was a huge focus for Hitler himself,
0:28:52 > 0:28:56and a big clue to that still lies beneath my feet.
0:29:03 > 0:29:06My guide to the tunnels under the palace is Leopold Stempowski...
0:29:06 > 0:29:08- How are you doing?- Hello.
0:29:08 > 0:29:10..who has lived in the castle grounds all his life.
0:29:13 > 0:29:14He tells me that work here
0:29:14 > 0:29:16was far more sophisticated than at the Riese,
0:29:16 > 0:29:18only a few miles away.
0:29:22 > 0:29:25Yeah, that's completely different, isn't it?
0:29:25 > 0:29:28Two storeys high, concrete-lined.
0:29:32 > 0:29:33Whoa!
0:29:33 > 0:29:35It's on a big scale, isn't it?
0:29:35 > 0:29:38It's a lot further advanced that the other tunnels I've seen.
0:29:38 > 0:29:40This must have been a priority for them.
0:29:59 > 0:30:02I can now see what all the concrete was used for.
0:30:05 > 0:30:08Leopold then showed me a peculiar section of wall.
0:30:09 > 0:30:12It could indicate that something incredibly big
0:30:12 > 0:30:13was being hidden here.
0:30:47 > 0:30:50Could these accounts of a large space behind this wall
0:30:50 > 0:30:54indicate the existence of a secret railway line out of the castle?
0:30:57 > 0:31:00So, what's interesting is, we are very close here
0:31:00 > 0:31:04to the site where those people claimed to have found a tunnel
0:31:04 > 0:31:06with perhaps a train in it.
0:31:06 > 0:31:09Surely that's related to this big facility here,
0:31:09 > 0:31:11because we're so close.
0:31:38 > 0:31:40Were there plans for a rail connection
0:31:40 > 0:31:43from these tunnels to the mainline at K65?
0:31:43 > 0:31:45It's possible, because we know
0:31:45 > 0:31:47that Hitler travelled everywhere on military trains
0:31:47 > 0:31:50and that most of his HQs had hidden railway access.
0:31:57 > 0:32:00It makes me wonder if this is what they were planning at the castle.
0:32:05 > 0:32:07While I was at the castle,
0:32:07 > 0:32:10they did tell me that there used to be a narrow gauge railway,
0:32:10 > 0:32:13a little service railway, that came off the mainline just here
0:32:13 > 0:32:15and possibly followed the line of this raised embankment here.
0:32:17 > 0:32:19What's fascinating, what's tantalising,
0:32:19 > 0:32:23is that we're now only 400 or 500 metres away
0:32:23 > 0:32:26from where the finders think they've identified that tunnel
0:32:26 > 0:32:28with the collapsed entrance.
0:32:28 > 0:32:30Could it have been...?
0:32:30 > 0:32:33Could it have been that the plan was to expand this railway,
0:32:33 > 0:32:37allow a full-scale train to go up to the castle,
0:32:37 > 0:32:39delivered the Fuhrer to his headquarters?
0:32:39 > 0:32:42In which case, that tunnel back down there,
0:32:42 > 0:32:47it could have been a facility in which to house the Fuhrer's train,
0:32:47 > 0:32:49keep it away from prying eyes.
0:32:51 > 0:32:54And that's why, because of the sensitivity around it,
0:32:54 > 0:33:00being designed for Adolf Hitler himself, it was disguised in 1945.
0:33:03 > 0:33:04It's possible.
0:33:07 > 0:33:10If they do find a tunnel at K65,
0:33:10 > 0:33:12the fact that Hitler himself could be connected to it
0:33:12 > 0:33:16gives this investigation a whole new level of importance.
0:33:16 > 0:33:19This could be a historical gold mine,
0:33:19 > 0:33:21whether there's treasure there or not.
0:33:28 > 0:33:30Back at K65, the Polish authorities
0:33:30 > 0:33:33are taking the claim that a tunnel exists seriously.
0:33:36 > 0:33:39But they're worried the Nazis may have booby-trapped the area.
0:33:42 > 0:33:45So before any dig can start, the army are sent in.
0:33:52 > 0:33:54This is just the latest in a series of hold-ups
0:33:54 > 0:33:56to hit the treasure hunters.
0:33:58 > 0:34:03In 2015, Piotr and Andreas' hopes suffered a dramatic setback.
0:34:03 > 0:34:05With so much speculation about the train,
0:34:05 > 0:34:07other experts got in on the act,
0:34:07 > 0:34:09carrying out their own surveys of the site.
0:34:12 > 0:34:15And at one packed press conference, with the world watching,
0:34:15 > 0:34:18the show was stolen by another team of experts,
0:34:18 > 0:34:21led by geophysicist Professor Madej.
0:34:25 > 0:34:27His announcement was a showstopper.
0:34:49 > 0:34:52I'm going to see the man who may have just killed our story.
0:34:54 > 0:34:57I'm interested to know why two sets of people
0:34:57 > 0:34:59could have such wildly different results.
0:35:03 > 0:35:05Professor Madej works at the renowned
0:35:05 > 0:35:08AGH University of Science and Technology in Krakow,
0:35:08 > 0:35:11the world's oldest geophysics department.
0:35:11 > 0:35:13HE SPEAKS POLISH
0:35:13 > 0:35:15His assistant is going to give me a demonstration
0:35:15 > 0:35:18of the magnetometer equipment they used at K65.
0:35:20 > 0:35:23- Is it heavy?- No, no.- Yes. Yes, yes.
0:35:23 > 0:35:28- Very heavy.- And you had to carry it all around that railway site?
0:35:28 > 0:35:32- Can I...?- Yeah. - Thank you.- That is heavy. Wow!
0:35:34 > 0:35:36And he makes you do this?
0:35:41 > 0:35:44- OK, it's good for you, it's good. - Yes.- OK.- So can I see how fast...?
0:35:44 > 0:35:47Let's go into the corridor. Let me see how fast you walk over the site.
0:35:47 > 0:35:48Come on.
0:35:51 > 0:35:54OK?
0:35:54 > 0:35:56OK, yeah. OK, go for it.
0:35:56 > 0:35:58Oh, so you can go quite fast, if you're looking for a big object.
0:35:58 > 0:36:00BEEPING
0:36:00 > 0:36:02Sounds like it's going crazy.
0:36:15 > 0:36:17And so when you were...
0:36:22 > 0:36:24Is this the exact equipment you used
0:36:24 > 0:36:27- to demonstrate there is no train down there?- No train.
0:36:33 > 0:36:36You're breaking hearts, saying there's no train.
0:36:43 > 0:36:47Professor Madej proceeded to give me the science behind his conclusion.
0:36:48 > 0:36:52He told me they had found some anomalies at the site,
0:36:52 > 0:36:54but these were quickly discounted.
0:37:31 > 0:37:33So, could the only gold train
0:37:33 > 0:37:35be this one on Professor Madej's desk...
0:37:36 > 0:37:39..and what the world is getting excited about
0:37:39 > 0:37:42be just a pipe lying a metre below the ground?
0:37:47 > 0:37:49Professor Madej's results seem damning,
0:37:49 > 0:37:52so I've decided to revisit the treasure hunters.
0:38:19 > 0:38:21Has it made your job more difficult
0:38:21 > 0:38:23because the scientists said there's nothing there?
0:38:23 > 0:38:25Is it now harder to get the excavation going?
0:38:54 > 0:38:57Andreas and Piotr are not giving up
0:38:57 > 0:39:00and are still planning to go ahead with their dig.
0:39:02 > 0:39:04In fact, they're so convinced they're right,
0:39:04 > 0:39:06they're investing their own money to prove it.
0:39:11 > 0:39:14While they sort out the finance and permissions for the dig,
0:39:14 > 0:39:17I want to look into how Nazi gold could have got here.
0:39:17 > 0:39:19The evidence I've gathered so far...
0:39:19 > 0:39:23A possible secret railway line linking the castle to K65,
0:39:23 > 0:39:26the spot where the treasure hunters want to dig.
0:39:26 > 0:39:29Plans for a new headquarters for Hitler.
0:39:29 > 0:39:31A network of underground tunnels,
0:39:31 > 0:39:34perhaps to house Hitler's weapons factories.
0:39:34 > 0:39:39The idea that Nazi treasures could have been sent here for safekeeping
0:39:39 > 0:39:41is, at the very, least plausible.
0:39:41 > 0:39:43But where did it come from?
0:39:43 > 0:39:46The answer could lie in the location itself.
0:39:47 > 0:39:53K65 marks the distance to the regional capital, Wroclaw.
0:39:53 > 0:39:56When Hitler came to power, it was called Breslau,
0:39:56 > 0:39:59and during the war, the city was a safe haven
0:39:59 > 0:40:02for valuable national treasures, as well as stolen Nazi loot.
0:40:06 > 0:40:09It was also the transit point for much of the gold and jewellery
0:40:09 > 0:40:12taken from Jews killed in the death camps.
0:40:12 > 0:40:16But by early 1945, the Soviet Red Army was at the gates.
0:40:21 > 0:40:24As the city prepared for a last stand,
0:40:24 > 0:40:27the Nazis desperately tried to move their valuables to safety.
0:40:32 > 0:40:34I'm meeting Professor Tomasz Glowinski,
0:40:34 > 0:40:37an expert on Breslau's wartime fate.
0:40:38 > 0:40:42He tells me what evidence there is for treasures leaving
0:40:42 > 0:40:45before the Soviets encircled and sealed the city.
0:40:58 > 0:41:00And do you think this is where
0:41:00 > 0:41:02the rumours of this gold train comes from?
0:41:02 > 0:41:04This evacuation of valuables from the city?
0:41:37 > 0:41:40As the Soviets closed in, Breslau descended into chaos,
0:41:40 > 0:41:43as people tried to flee by any means possible.
0:41:48 > 0:41:51The main station was crowded with civilians
0:41:51 > 0:41:53desperately seeking a way out of the city.
0:41:56 > 0:41:59So, could a train with a cargo full of gold
0:41:59 > 0:42:01have left Breslau at this point,
0:42:01 > 0:42:03slipping out amidst the confusion and panic?
0:42:11 > 0:42:12It is possible to believe
0:42:12 > 0:42:16that this city was in such a state of chaos and uproar
0:42:16 > 0:42:19that a shipment of gold could have made it here in trucks,
0:42:19 > 0:42:23unobtrusively transferred onto a train and taken out of town.
0:42:23 > 0:42:25It would have been a crazy time.
0:42:25 > 0:42:27These platforms thronged with refugees
0:42:27 > 0:42:30trying to escape the clutches of the Russians.
0:42:30 > 0:42:33And it strikes me that a small shipment...
0:42:33 > 0:42:36It could have slipped out of the city.
0:42:36 > 0:42:38People weren't taking notes in triplicate and filing them.
0:42:41 > 0:42:43It is possible.
0:42:58 > 0:43:00Back at K65,
0:43:00 > 0:43:04Andreas and Piotr have finally been given permission by the authorities
0:43:04 > 0:43:06to clear the area in preparation for their dig.
0:43:12 > 0:43:16Crowds have started to gather to get a sneak peek,
0:43:16 > 0:43:17but our treasure hunters
0:43:17 > 0:43:20have decided to fence the dig off from the public
0:43:20 > 0:43:22in order to keep anything they find private.
0:43:24 > 0:43:26While we wait for the dig to begin,
0:43:26 > 0:43:29I've been looking for evidence that gold was hidden
0:43:29 > 0:43:31in the hills and mountains around K65,
0:43:31 > 0:43:33and I think I've found it.
0:43:39 > 0:43:41HE SPEAKS IN HIS OWN LANGUAGE
0:43:43 > 0:43:45This is fantastic.
0:43:45 > 0:43:50Classic golden age Polish television from the 1970s.
0:43:50 > 0:43:52Might not look that much to the modern eye,
0:43:52 > 0:43:55but this is actually a vital clue
0:43:55 > 0:43:59into whether any German gold could have got out of Breslau
0:43:59 > 0:44:01before the Soviets arrived.
0:44:01 > 0:44:04HE SPEAKS IN HIS OWN LANGUAGE
0:44:04 > 0:44:08In the interview, a member of the Polish Security Service
0:44:08 > 0:44:11claimed the Nazis had hidden large quantities of gold
0:44:11 > 0:44:13in nearby mountains.
0:44:13 > 0:44:17The man at the root of this mystery is Herbert Klose.
0:44:17 > 0:44:21Klose claimed to have been a vet in the Wehrmacht,
0:44:21 > 0:44:26though Polish Intelligence in fact believed he'd been an SS officer.
0:44:29 > 0:44:30Klose's being a little bit evasive,
0:44:30 > 0:44:32but he does admit to taking part in an operation
0:44:32 > 0:44:36where 50 chests of gold were taken out of Breslau,
0:44:36 > 0:44:37and he even says where he took them.
0:45:03 > 0:45:06The film followed the route that Klose claims to have taken,
0:45:06 > 0:45:10and I've decided to retrace it, too, up into the mountains.
0:45:14 > 0:45:18Jelenia Gora is in the same mountain range as Walbrzych
0:45:18 > 0:45:20and only 50 kilometres from K65.
0:45:25 > 0:45:29According to Klose, they brought the treasure on the back of trucks
0:45:29 > 0:45:31up here to the slopes of Mount Sniezka,
0:45:31 > 0:45:34which is on the modern Polish-Czech border.
0:45:38 > 0:45:40Up here, high in the mountains,
0:45:40 > 0:45:45they transferred that treasure from the trucks to horseback.
0:45:45 > 0:45:48Now they went up the hill on the horses with the treasure,
0:45:48 > 0:45:50and at that point, he tells interrogators
0:45:50 > 0:45:53that he fell off his horse and got an injury.
0:45:53 > 0:45:56Well, slightly convenient, you might think.
0:45:56 > 0:45:58He goes back down, he goes to hospital,
0:45:58 > 0:46:02and he's not there when the treasure is deposited for safekeeping
0:46:02 > 0:46:04somewhere in these hills.
0:46:04 > 0:46:07One of his comrades comes back down, visits him in hospital,
0:46:07 > 0:46:11and tells him that the mission was completed, the treasure was stowed.
0:46:11 > 0:46:13But he, of course, claims he doesn't know where it is.
0:46:14 > 0:46:19It does mean that I could be just metres away from Nazi gold now.
0:46:20 > 0:46:22I've got to get out of Silesia.
0:46:22 > 0:46:24I've got gold fever, like everyone else in this place.
0:46:24 > 0:46:26Going crazy.
0:46:26 > 0:46:28But it is tantalising.
0:46:34 > 0:46:35The Klose story is evidence
0:46:35 > 0:46:38that the Nazis were hiding secret cargoes of gold
0:46:38 > 0:46:41in the mountains not far from Walbrzych.
0:46:41 > 0:46:45So if there is any secret tunnel at K65,
0:46:45 > 0:46:47one of those cargoes could have ended up there.
0:46:58 > 0:47:02The diggers are moving in, and after a year of growing anticipation,
0:47:02 > 0:47:04the excavation has finally begun.
0:47:16 > 0:47:20Andreas and Piotr have assembled a team of 64 people,
0:47:20 > 0:47:22many local volunteers,
0:47:22 > 0:47:25and they're confident of uncovering a secret Nazi tunnel and train.
0:47:36 > 0:47:40So far on this journey, I've been down tunnels, I've visited castles,
0:47:40 > 0:47:45I've seen the appalling human cost of the mad Nazi building plans,
0:47:45 > 0:47:48I've followed the journey of Nazi gold,
0:47:48 > 0:47:51and now I'm back here at Kilometre 65.
0:47:51 > 0:47:54Behind me, the dig is just beginning,
0:47:54 > 0:47:56and we are finally going to find out
0:47:56 > 0:48:00whether those treasure seekers have got exactly the right place,
0:48:00 > 0:48:02as they believe, and whether there's gold down there.
0:48:07 > 0:48:10Piotr and Andreas have opened up several trenches
0:48:10 > 0:48:12along the top of the embankment,
0:48:12 > 0:48:15where their surveys indicate the tunnel is located.
0:48:16 > 0:48:19They've also been doing new scans of the area,
0:48:19 > 0:48:21which they say back up their original findings.
0:48:40 > 0:48:43The new scans have instilled confidence in the team
0:48:43 > 0:48:45that they will definitely find something.
0:48:45 > 0:48:48THEY SPEAK POLISH
0:49:04 > 0:49:08Everything in this investigation suggests that it is just possible
0:49:08 > 0:49:11that gold could be hidden somewhere in these mountains.
0:49:11 > 0:49:14But is it at Kilometre 65?
0:49:14 > 0:49:17Before I find out if Andreas and Piotr are right,
0:49:17 > 0:49:19there's one last story that I want to explore.
0:49:21 > 0:49:25When I first came here, 85-year-old miner Tadeusz Slowikowski
0:49:25 > 0:49:30told me that the Nazi security around K65 was very tight,
0:49:30 > 0:49:34and that some local residents living near the tunnel entrance were killed
0:49:34 > 0:49:37as the Soviets approached Walbrzych on the last day of the war.
0:49:39 > 0:49:41So are you saying that the Nazis
0:49:41 > 0:49:43murdered the people who lived in these houses?
0:50:07 > 0:50:10Tadeusz thinks these murders are evidence
0:50:10 > 0:50:14that the Nazis wanted to keep their activities at K65 secret.
0:50:15 > 0:50:17A secret so significant
0:50:17 > 0:50:20that uncovering it could cost you your life.
0:50:23 > 0:50:26This intrigues me, because while I've uncovered some evidence
0:50:26 > 0:50:29that a gold train might be buried around here somewhere,
0:50:29 > 0:50:32this could help pinpoint it to the exact place
0:50:32 > 0:50:35where the treasure hunters are digging.
0:50:36 > 0:50:39I've decided to try and check it out.
0:50:39 > 0:50:43Frustratingly, the original house has since been demolished.
0:50:44 > 0:50:47But incredibly, given all the death and mayhem
0:50:47 > 0:50:50of the last stages of the war, the murder of these three people
0:50:50 > 0:50:53was actually recorded in a local church register.
0:50:56 > 0:50:58It's the first time I've actually been able to sit down
0:50:58 > 0:51:01with some real evidence in black and white,
0:51:01 > 0:51:04written down at the time of these events that I'm trying to unravel.
0:51:04 > 0:51:07It's evidence that three women were murdered
0:51:07 > 0:51:11in exactly the place that we're fascinated by,
0:51:11 > 0:51:14metres away from this secret railway siding.
0:51:14 > 0:51:17But tragically, frustratingly, it doesn't tell us who did it.
0:51:17 > 0:51:19And it puts the date
0:51:19 > 0:51:22at exactly the time when it could have been either side.
0:51:22 > 0:51:25The German Army were in the process of collapsing,
0:51:25 > 0:51:28this was the last day of the Third Reich,
0:51:28 > 0:51:30and the Soviet Army were on the fringes of town,
0:51:30 > 0:51:32about to push in and take over.
0:51:32 > 0:51:37It's an absolute turning point in world history,
0:51:37 > 0:51:40and these three women were killed at that time.
0:51:40 > 0:51:43The fact is, this doesn't get us any closer
0:51:43 > 0:51:46to being definitive about whether there's a tunnel under that hill
0:51:46 > 0:51:49and whether it was deliberately disguised.
0:51:58 > 0:52:04Back at the dig, and like me, Piotr and Andreas have hit a dead end.
0:52:04 > 0:52:07What they thought was the top of the tunnel
0:52:07 > 0:52:09is in fact a glacial deposit,
0:52:09 > 0:52:13intricate rock formations dating back millions of years,
0:52:13 > 0:52:16and the train they thought they'd seen on their scan
0:52:16 > 0:52:18hasn't yet materialised.
0:52:18 > 0:52:21I get the sense they're not feeling quite as confident
0:52:21 > 0:52:22as they once were.
0:52:24 > 0:52:26Where does your scan show that the train was?
0:52:43 > 0:52:46So you're saying, "There is still a tunnel here, we just haven't found it yet"?
0:52:58 > 0:53:00Piotr and Andreas are saying that to dig deeper,
0:53:00 > 0:53:02they need heavy drilling equipment,
0:53:02 > 0:53:05and they require extra permissions from the authorities
0:53:05 > 0:53:06before continuing.
0:53:08 > 0:53:12For now, the treasure hunters have no choice but to fill the hole in.
0:53:16 > 0:53:19Well, the dig has officially finished,
0:53:19 > 0:53:21and we can now say for certain
0:53:21 > 0:53:26that the hunt for the Nazi gold train has produced no Nazis,
0:53:26 > 0:53:29no gold and no trains.
0:53:31 > 0:53:33I've got to admit, I'm a little bit gutted.
0:53:33 > 0:53:36I tried to remain sceptical throughout,
0:53:36 > 0:53:38but a little part of me wanted to believe,
0:53:38 > 0:53:40a little part of me hoped that there would be a gold train down here
0:53:40 > 0:53:43and that I would be privileged enough to witness
0:53:43 > 0:53:45one of the most remarkable moments
0:53:45 > 0:53:47of archaeological discovery of all time.
0:53:49 > 0:53:51But instead, there's nothing.
0:54:13 > 0:54:16It's frustrating that no gold train has yet been found,
0:54:16 > 0:54:20but I think I've uncovered an even more compelling story.
0:54:21 > 0:54:25Could the secret Riese tunnel complex and the remodelled castle
0:54:25 > 0:54:29reveal one of Hitler's final and most ambitious plans?
0:54:30 > 0:54:32Was he hoping to retreat here,
0:54:32 > 0:54:35relocating his weapons factories to the tunnels below
0:54:35 > 0:54:39and then fighting on from this final defensive redoubt?
0:54:42 > 0:54:45If this was his plan, then perhaps it makes it more likely
0:54:45 > 0:54:50that there is a gold train hidden somewhere in these hills.
0:54:50 > 0:54:54And maybe it's just a matter of time till someone finds it.
0:54:57 > 0:55:01As I was preparing to leave, I got a surprise call from Wojtek,
0:55:01 > 0:55:04the local film-maker I first met when I arrived,
0:55:04 > 0:55:08asking me to meet him half a kilometre away from the dig.
0:55:08 > 0:55:10He was the man who first persuaded me
0:55:10 > 0:55:13there could be something to this legend.
0:55:13 > 0:55:16He still thinks our treasure hunters are onto something,
0:55:16 > 0:55:19but they're not digging in quite the right place.
0:55:20 > 0:55:22You see, I came onto this piece of land with you
0:55:22 > 0:55:24and you convinced me the train was here.
0:55:24 > 0:55:27I was so excited because of these what might be ventilation shafts
0:55:27 > 0:55:29or hatch covers or something.
0:55:29 > 0:55:30Why aren't they digging here?
0:56:01 > 0:56:04So, the treasure hunters never found their gold.
0:56:04 > 0:56:06But it's not going to stop them.
0:56:06 > 0:56:09And the reason is because this part of Europe
0:56:09 > 0:56:10has such an extraordinary history,
0:56:10 > 0:56:16a history of conquest, tumult, population shift, hidden tunnels,
0:56:16 > 0:56:19bunkers, buried treasure,
0:56:19 > 0:56:22and all of that ensures that no-one in this area
0:56:22 > 0:56:25is ever going to stop looking for Nazi gold.
