Prora  is a site on the German Baltic Sea island Rügen. During the Nazi-German era the worker's organization Kraft durch Freude (Strength through joy) began building a huge beach resort hotel for 20 000 people at the shore of the Baltic Sea. The project was almost finished when World War II started, but it did never get into use. In the East German era the site was used as a military base. In the 90's parts of it was opened as a museum, but most parts of the megalomanic 4,5 kilometers (about 2,8 miles) long building complex is empty. Prora is also known as the Colossus of Rügen.
You can get around the site by foot; however, if you want to see the whole building complex from end to end you might want to take the car.
The Baltic Sea beach is still in use today.
There is a cafe in the museum.
In 2011, the disused site re-opened as a youth hostel.
