The Obersalzberg Documentation is a permanent Institute of Contemporary History Munich – Berlin exhibition about the history of Obersalzberg and the Nazi dictatorship.

Obersalzberg, which became Hitler's holiday retreat in 1923, was expanded after 1933, becoming a second seat of government next to Berlin. In contrast to all other comparable institutions (concentration camp memorial sites, holocaust museums, local documentation centres on the Nazi past) and temporary exhibitions on the Nazi period, the Documentation does not limit itself only to local history and sections of historical reality, but combines the history of the Obersalzberg with the central manifestations of the National Socialist dictatorship.
