The Stasi was the GDR’s infamous secret police force. Considering itself the “shield and sword of the party” it ran a covert war against perceived enemies of the state.The Stasimuseum is located in House 1 on the former grounds of the headquarters of the GDR Ministry for State Security (MfS). The building was erected in 1960-61 as the offices of Erich Mielke, who served as Minister for State Security from 1957 until the end of the GDR.
On 15 January 1990 demonstrators took over the Stasi headquarters. A week later, the Central Round Table, a committee made up of representatives of the SED dictatorship and civil rights groups, decided that a “memorial and research centre on GDR Stalinism” should be established in House 1. When nothing came of this declaration of intent, members of the Berlin citizens’ committee and other civil rights activists took action and began securing the historic site. In August they founded the association “Antistalinistische Aktion e.V.” (ASTAK). On 7 November 1990, it opened the Research Centre and Memorial at Normannenstrasse with an exhibition titled “Against the Sleep of Reason”. House 1, later named the Stasi Museum, has been open to the public ever since.
The offices of Erich Mielke are preserved in their original condition and form the centrepiece of the historic site.
Since 1990, ASTAK has shown different exhibitions, providing information about the State Security and how its activities affected the GDR population. The permanent exhibition “State Security in the SED Dictatorship,” which the association created jointly with the Stasi Records Agency, opened in House 1 in January 2015.
