The Cecilienhof Palace in Potsdam was built during WW I as a residence for the last Crown Prince Wilhelm and his wife Cecilie. Although the monarchy had ended in 1918, they continued to live there until 1945. From 17th of July to 2nd August, 1945 the Potsdam Conference was held in the palace. During this summit meeting, the US President Harry Truman, the British Prime Minister Winston Churchill, and the Soviet dictator Josef Stalin deliberated on post-war policies. Today the palace is mainly used as a hotel. The historic rooms of the Potsdam Conference and some of the private rooms of the former Crown Prince and his wife can be visited.
