Hohenschönhausen Memorial

"The memorial in Hohenschönhausen has been open to visitors since July 2000. The historical site [...] looks back on an eventful history that is closely intertwined with the history of the GDR. The memorial informs visitors through exhibitions, publications and events about the forms and consequences of the communist dictatorship using the prison as an example. [...] The site was in Soviet hands from May 1945. The former canteen kitchen of the National Socialist People's Welfare Organization was transformed into a collection and transit camp. Around 1,000 prisoners - mainly spies, saboteurs, terrorists, members of the police and so-called "enemy elements" - died due to the catastrophic living conditions and were buried anonymously in mass graves.

At the end of 1946, the collection camp became a prison for the Soviet occupying forces. Suspected political opponents in particular were imprisoned and tortured there. In 1951, the Ministry for State Security (MfS/Stasi) took over the site. Over 11,000 people were held there and subjected to physical and psychological violence. The prison closed on October 3, 1990."
