The Stasi Museum (also known in German as the Forschungs- und Gedenkstätte Normannenstraße) is a research and memorial centre concerning the political system of the former East Germany. It is located in the Lichtenberg locality of Berlin, in the former headquarters of the Stasi (officially the Ministerium für Staatssicherheit), on Ruschestraße, near Frankfurter Allee and U-Bahn station Magdalenenstraße. The centrepiece of the exhibition is the office and working quarters of the former Minister of State Security – i.e. head of the Stasi – Erich Mielke.
