Churchill, Truman, Stalin: the three of them wrote world history here and discussed how to partition Germany. From 17th June to 2nd August 1945, the victorious powers of World War II met in the venerable halls of Cecilienhof Palace for the Potsdam Conference. Originally, Cecilienhof Palace was built from 1914 to 1917 for Crown Prince William and his wife Cecilie von Mecklenburg-Schwerin as the last construction of a castle of the Hohenzollern dynasty. In his design plans, the architect Paul Schultze-Naumburg orientated himself towards the English country houses in the Tudor style. Today, the castle is an historic memorial, in which the conference room and the working rooms of the participants in the Potsdam Conference can be visited.
