The KDF Bad Prora was meant to be an immense holiday centre – sea resort and would house 20,000 people. The project, designed by Clemens Klotz, won the architecture prize at the 1937 Paris World Exhibition. Only part of it was built between 1936 and 1939. After WW2 the Soviet Army installed an army base at Prora. The 8 gigantic building blocks, already forming an impressive construction, were abandoned after the Soviets left.
