After the end of the Second World War, the victorious powers – the United States, England and Russia – met here to discuss the future of Germany at the Potsdam Conference: at Cecilienhof Palace in Potsdam. At this momentous historical event, the Potsdam Agreement set the stage for the Cold War. Built from 1913 to 1917 in the English country house style, the Hohenzollern Palace was the residence of the last German Crown Prince and Crown Princess Wilhelm and Cecilie of Prussia until 1945. At first glance, it is not obvious that the castle has a whole 176 rooms. The reason: the design with individual structures grouped around several interior heights.
