Description: Prora, also known as the Colossus of Prora, is an enormous building complex on the island of Rügen, Germany, that was built by Nazi Germany between 1936 and 1939 as a beach resort of the Strength Through Joy project. It consisted of eight identical buildings and was 4.5 km (2.8 mi) in length parallel to the beach, with the surviving structures stretching 3.0 km (1.9 mi). Although the buildings were planned as a holiday resort, construction was not completed and they were not used for this purpose. After World War II, the complex found various military uses, first by the Soviet Army, then by the East German Volksarmee, and then by the German Bundeswehr. Today it houses a large youth hostel, a hotel and vacation apartments.
