Dressed like a member of former East Germany's National People's Army, Thomas Krueger stands in a forest where a Cold War bunker lies concealed. The bunker is now a museum that allows guests to experience something of life in the old communist state for themselves. Visitors can come and stay for a night, during which they don army uniforms and are treated as East German soldiers. Staying at the museum is a far cry from a night in a plush hotel. On arrival, guests are issued with National People's Army trousers, jackets, belts, caps and a gas mask, and are then ordered to march through the fir trees and find the bunker. It might not sound like everybody’s idea of fun. But the Waldhotel Rennsteighoehe, which runs the museum, says there is plenty of demand for the experience, which can cost visitors 109 euros each, depending on the size of their group. Among those who have signed up for an overnight stay are these members of the Hoppmann family, pictured trying on their gas masks. A headless mannequin sits by a table of typewriters at the museum, infusing the scene with an even greater sense of the surreal. The eerie atmosphere is fitting. The bunker, whose entrance is concealed by a hut with army tanks parked outside, was built in the 1970s and run by the dreaded Stasi secret police, who imprisoned thousands of citizens they deemed to be opponents of the state. Its purpose was to enable a military elite to run a command centre in the event of an attack, and to survive after most of the local population was wiped out. One of the guests at the bunker was 66-year-old Hans-George Tiede, who had lived under communism and was a conscript in the National People's Army in 1972-3. This is his old army identity card. Tiede, who stayed at the museum with his two sons said the visit was "thought-provoking." "It made me think, once I found out that such constructions were built in the east back then. How much money was thrown at a handful of people so they might live 14 days longer?" he said. "It brought home how manipulated people were and can be." Thomas Krueger, dressed as a National People's Army (NVA) major, speaks to guests taking part in the bunker museum's "reality experience". A man dressed as an NVA officer watches participants at the museum. Krueger talks to guests clad in NVA uniforms. A piece of paper sticking out of a typewriter at the museum reads: "Dear friends of the bunker. We are happy that you are here tonight." Equipment stands on the table of a telephone exchange room at the museum. A couple dressed as NVA soldiers look at photos and communist memorabilia hanging on the wall. A photo of former East German leader Erich Honecker is stuck to a map at the museum. An overall to protect against chemical weapons sits on a bench in the bunker. A Trabant car - an iconic symbol of former East Germany - is pictured at the museum. Marco, a museum staff member dressed as an NVA officer, inspects the bunker. Andrea Friebe, a 37-year-old fitness coach, poses as she takes part in the "reality experience". Hans-Georg Tiede holds up his old East German dog tag as he arrives for a night in the bunker. A kit for measuring levels of the chemical Sarin is seen at the bunker. Guests dressed in NVA uniforms prepare dinner. Visitors at the bunker walk past Thomas Krueger, who stands dressed as an NVA major. A man dressed as an NVA officer is silhouetted against the sky. Participants in the reality event line up as they are addressed by a man acting as an NVA major. One Saturday morning, I set out to travel back in time to a place in eastern Germany. I was going back to the era of the former German Democratic Republic (GDR), when Germany was two countries, with two different armies. I was going to the Bunker Museum in Rennsteighoehe, in the middle of the forests of Thuringia. The museum is owned by the Waldhotel Rennsteighoehe, which offers visitors the chance to come there for a historical “reality experience”. This means spending the night in a bunker built by the Ministry of National Defence, wearing the uniform of the former communist National People's Army (NVA), and being treated like an East German soldier for the night. I arrived in the middle of the forest with 14 others, who were also taking part in the reality event. First, everybody had to choose their trousers, jackets, belts and caps. A gas mask was also essential. Then a man dressed like a major appeared with a frightening look in his eyes and told us sternly to find the bunker where we were staying, which was supposed to be some 30 km (18 miles) away. We set off through the forest with our luggage, and were happy when we came across the bunker after just 100 meters (110 yards), rather than 30km. At the entrance was a man who looked like an NVA officer. He welcomed us, but not with any warm words. Instead, he gave us commands, as he would have done in times gone by. Being there brought to mind my first encounter with the NVA. It happened when I was visiting friends in Berlin in 1986, and had to use the 200-km (124-mile) transit motorway through the former GDR. I waited at customs for hours and hours, thinking: don’t do anything, stay calm, don’t smile, be serious. After what seemed like an eternity of waiting, my turn came to be checked by the NVA soldiers. I was afraid. They looked me in the eyes, asked me where I was going, how long I was staying there, what the reason was for my trip, and whether I was smuggling anything. Then they took my passport away for 10 minutes. When they returned, they didn’t say a word, but inspected my car and luggage inside and out. The process took around 15 minutes, and then I was on my way to Berlin. They found nothing. Now, at the Bunker Museum, I was among 14 people who had paid for an experience with the NVA. The officer opened up the bunker and escorted us to our dormitory. Everybody was responsible for making their own small, uncomfortable bed. The women were then told to cut potatoes for a salad and the male soldiers had to stand guard at the entrance. One soldier had to get the barbecue ready. I was happy that dinner did not consist of old soup, but instead of Thueringer Bartwurst, a regional specialty. At this point, the major and officers began telling us stories about the bunker and its history. Marco, who was dressed as an officer, had been a real soldier in the NVA when the Berlin Wall came down in early November 1989. He had to continue working as a soldier, without any days off, until the middle of December. It must have been strange for him to see all those people, his own family included, celebrating the fall of the Wall when he had to ignore it. He said it was not easy. Some time later, he decided that he would never be a soldier again. Later, his girlfriend asked him to be a guide at the Bunker Museum, where he could use all his knowledge of the period. Because he was so in love with her, he agreed and has been working as one of the uniformed guides here for more than 10 years. He is also the caretaker and concierge at the hotel. He says sometimes older people who spend a night at the bunker still have the Wall in their minds. Old memories come flooding back, and for some people they are only positive – all the bad stuff is forgotten. There was a couple in our group who were the only ones from former West Germany. Nearly all the guests at the bunker had come after receiving a voucher for the event as a birthday present. Most of the male participants had been NVA soldiers – if you lived in the former GDR, you had to serve, otherwise you would go to prison or your family would pay the consequences. Someone told me that almost every man from former East Germany aged over 40 had been a soldier in the NVA. In the evening we all had a few beers together, some people sipped Vodka and women drank the typical east German sparkling wine ‘Rotkaeppchen’. At midnight, people were tired and a chorus of snores broke out. Someone dreamt and spoke in Russian. So many memories. Good or bad - who knows? After morning exercises led by Andrea Friebe, who works as a fitness coach, everybody was happy in the knowledge that they’d be sleeping in their own beds the following night. We ate breakfast and bid each other Auf Wiedersehen. It was an interesting event in terms of seeing how much has changed since the time of the GDR – in people’s minds, as well as in practical terms. And it was nice to be there without any more angst over customs inspections! When Saveway President Dr. Manfred Hopf invites you to a conference, you can expect a very interesting program and to meet a whole lot of experts. The moderator, Prof. Dr.-Ing. Egbert Baake, began by welcoming renowned speakers and gave participants a clear picture of the current state of the industry. Heiko Lickfett (BDG) reported positive tendencies in German cast iron in 2017, and Prof. Dr.-Ing. Gotthard Wolf (TU Freiberg) promoted participation in the Materials Competition and reported excellent future prospects for highly motivated students and doctoral students in the field of iron casting. As a supplier for measuring technology, Saveway is very close to the field, so the main part of the two-day event focused on the practitioners, who presented the necessities and trends for the delivery of ovens in melting plants in various case studies. "Go and See," is what President of Sachsen Guss and Franken Guss, Josef Ramthun, names his credo. The director of the melting plant is also tasked with looking inside and under its melting devices. Ramthun, a passionate specialist, knows what he is talking about when he says, "The safety of production in the melting process is vital." He therefore advocates the safety of metrology, through the product of companies like Saveway, before an oven burns through. Frank Zaremba | Chemikalien-Gesellschaft Hans Lungmuß mbH & Co.
