The Sportmuseum Berlin is an amalgamation of the Sporthistorisches Kabinett Berlin, the Sammlungszentrum Zentrales Sportmuseum of the GDR and the West Berlin Forum für Sportgeschichte e.V. It is in the tradition of the Museum für Leibesübungen zu Berlin (Berlin Physical Exercise Museum) which was founded in 1925 and closed down by the Nazis in 1934. Its more than 100,000 objects and a collection of around 1.5 million photos make the Sportmuseum Berlin the biggest sports collection in Germany. The library holds around 37,000 titles from the literature of the history of sport from three centuries, including the magazines of all German sports clubs East and West from 1945-6 to 1989. The museum is sited in Berlin’s Olympic Park. In the House of German Sport it shows rotating travelling and special exhibitions on various topics to do with sporting history in Berlin and Brandenburg, in Germany and internationally. The museum offers guided tours of the exhibitions, project days for school classes, tours of the museum depot store and guided tours of the Berlin Olympic Park with its facilities and buildings of interest from a sports, architectural and art historical point of view.
