The Stasi minister Erich Mielke had his office in House 1 from 1962 to 1989. The building now accommodates the Stasi Museum with the exhibition "State Security in the SED Dictatorship". Erich Mielke's historical office rooms form the core of the museum.
The adjacent buildings house the offices of the Federal Commissioner for the Stasi Records (BStU). The Stasi records themselves are stored in House 8. The Stasi archive can be viewed on public guided tours. From April to October, the BStU also offers tours of the complex.
In one building section on Ruschestraße, the German Red Cross currently runs an emergency shelter for refugees with the aid of many volunteers.
