Cecilienhof Palace, located in the northern part of Potsdam, Germany, is a historic building completed in 1917. This palace gained international fame when it served as the site of the Potsdam Conference from July to August 1945, where leaders from the Soviet Union, the United Kingdom, and the United States, including Stalin, Churchill, Attlee, and Truman, negotiated terms for the end of World War II. Cecilienhof is an example of Tudor style architecture, featuring numerous chimneys and gables, and it was the last palace built by the House of Hohenzollern. The palace, surrounded by lush gardens and located near the Heiliger See, is part of the Palaces and Parks of Potsdam and Berlin UNESCO World Heritage Site. It has been turned into a historical museum that offers insights into the conference and the end of the war. Visitors can also see the private quarters of the palace's former residents, Crown Prince Wilhelm and his wife, Cecilie, after whom the palace is named.
