Wannsee House 2 - After the Second World War, the villa is handed over to the political party SPD who establish an educational centre called the August-Bebel-Institute. It serves as a school between 1952 and 1982. In 1982, Richard von Weizsäcker, Berlin's mayor, designates the house a memorial, and since 1992, on the 50th anniversary of the Wannsee Conference, it becomes an official museum and educational centre.
