Cecilienhof Palace has been closed for renovations since November 2024. Plans include a new, expanded visitor reception area, a public restaurant, an elevator for barrier-free access, and the reactivation of the hotel spaces, which will be used accordingly once the renovations are complete. During the renovation, however, the palace can be explored digitally: Google Arts & Culture offers free virtual tours of the historic rooms of the Potsdam Conference as well as extensive digital exhibitions on various aspects of the palace's history and its use.

Churchill, Truman and Stalin in Cecilienhof Palace im New garden World history was made. They met here in the summer of 1945 for Potsdam Conference and sealed the fate of Germany and Europe. The house was built between 1913 and 1917 in the style of an English country house. Kaiser Wilhelm II had it built for his eldest son, Crown Prince Wilhelm, and his wife Cecilie.

After the collapse of the monarchy, Wilhelm was allowed to return to Potsdam in 1923 and was granted lifetime residency rights in the palace, which had by then been expropriated by the state. At the end of the Second World War, the former Crown Prince fled with his family from the advancing Red Army.

The castle now houses a historical memorial site where the conference rooms and workrooms of the participants of the Potsdam Conference can be visited.
