This immense "cottage" of over a hundred rooms was built during the First World War for the Crown Prince and his wife Cecilia. It has since been turned into a luxury hotel. Set in the Neuer Garten, it hosted the historic Potsdam conference in 1945 between Stalin, Truman and Churchill. Inside the palace, admire the private study of the Crown Princess, the Princess’s apartment furnished in the style of a yacht’s cabin, as well as the conference rooms and room where the 1945 agreement was signed.
