As part of this year’s 20th anniversary celebrations of the fall of the Berlin Wall, the German Chancellor has visited the main detention centre of the GDR’s secret police, the Stasi.Angela Merkel, herself born in East Germany, is the first German leader to visit Hohenschönhausen. She paid tribute to victims of the Stasi’s harsh espionage and interrogation tactics. “It is very, very important that we don’t forget this chapter of the East German dictatorship. We must encourage people again and again to talk about what really happened back then,” she said. Thousands of enemies of the state passed through the gates of Hohenschönhausen. Today survivors show visitors around the site, which is now a memorial museum.
