Prora, also known as the Colossus of Prora, is a building complex on the island of Rügen, Germany, that was built by Nazi Germany between 1936 and 1939 as a beach resort of the Streng Through Joy (Kraft durch Freude or KdF) project. It consisted of eight identical buildings and was 4.5 km in length parallel to the beach, with the surviving structures stretching 3.0 km. The KdF-seaside resort Rügen was an important element of the social propaganda of the "Third Reich". As the largest architectural project of the "Third Reich" Prora is of high importance both with its building history and social history. 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. I visited it in 2007 when it was still abandoned. Today it houses a large youth hostel, a hotel and vacation apartments.
