Prora is a beach resort built in the 1930-ies on the island of Rügen, Germany. The structure itself extends impressive 4.5 kilometer. The design won the Grand Prix award at the 1937 Paris World Exposition. Decisive for the Monument Protection Authority were “the impressive and characteristic cubic structure of the building body” and the “reinforced concrete skeleton construction, cast on site”. Never finished, it is now built into luxury apartments.
