The former KGB (State Security Committee) headquarters in Tallinn is located in the heart of the Old Town. The building has long been a symbol of former Soviet oppression in Estonia, and for thousands of Estonians, the path of suffering began here. In 1941 the ESSR established prison cells in the basement of the building, where suspected enemies of the state were imprisoned and interrogated before being shot or sent to labor camps in Siberia. The basement windows were intended to muffle the sounds of interrogations and torture; Although the detention center was used until 1950, the actions taken between the walls are still vivid in memories to this day.
