The East German Ministry of State Security (or Stasi) used what is today known as the Gedenkstätte Berlin-Hohenschönhausen as their main prison. Take a tour led by a former inmate to hear first-hand details of the interrogation methods used.
Gedenkstätte Berlin-Hohenschönhausen creates a lasting memorial to the people who survived the terror of the Stasi and the families of those who didn't. Hearing how inmates used to be crammed into a cupboard, standing up for days on end in puddles of water, from someone who has actually done it is something you just won't find in a history book.
