Holiday in an East German bunker

37 year-old Andrea Friebe, who works as fitness coach, dressed in a NVA soldier uniform, poses during her 'reality event' at the 'Bunker-Museum' in Rennsteighoehe near the eastern city of Ilmenau October 12, 2013. The museum is a former East German bunker, built in the 1970s to shelter the district's command unit in an emergency. The 3,600-square-meter bunker now offers visitors the chance to stay there overnight as part of a historical "reality experience". Depending on the size of their group, guests can pay 109 euros each for a 16-hour stay, during which they wear National People's Army (NVA) uniform and are treated as former East German soldiers for a night.
