Cecilienhof Country House in the New Garden

World history was written at Cecilienhof Country House in the summer of 1945. Following the end of fighting in Europe, World War II’s three main Allies met here to discuss the continent's reorganisation and Germany's future. The results of this conference, officially known as the “Three Power Conference of Berlin,” were laid out in the Potsdam Agreement and the Potsdam Declaration.

The permanent exhibition in Cecilienhof Country House presents a wealth of historical photographs and multilayered information (in German and English) at its authentic location, allowing a vivid image of events surrounding the conference (from July 17–August 2, 1945) to come to life. The decisions of the Potsdam Protocol are presented directly at the site in which they were negotiated in 1945—by Churchill followed by Attlee, Truman, and Stalin—in the Conference Hall, the centrepiece of Cecilienhof‘s historical memorial, with its famous round table.

An audio guide enhances a visit to the exhibition. Among other original recordings, statements by Churchill, Truman, and Stalin can be heard. The audio guide is available in eleven languages: German, English, French, Italian, Spanish, Polish, Russian, Hebrew, Japanese, Chinese, and Korean.

In addition to the political events of 1945, the exhibition delves into the palace's construction and the history of its former residents: Crown Prince William (1882–1951) and Crown Princess Cecilie (1886–1954) of Prussia, for whom Cecilienhof Country House was built from 1913-17. The royal couple lived at the palace until February 1945.
