KGB Prison, Potsdam, Cold War detention facility in Potsdam, Germany.
The KGB Prison is a three-story building containing 36 cells that preserves the original structure of a Soviet detention facility. Its rooms still display inscriptions left by prisoners, along with interrogation areas and spaces that convey how the place functioned.
Between 1945 and 1991, the building served as a Soviet military prison holding German civilians and Soviet personnel captured during conflict. Those detained faced interrogation before many were transported eastward to face harsh punishment.
The site serves as a memorial to those held within its walls and the experiences they endured. Displays showcase personal belongings and photographs that bring individual stories from that period to life.
The museum is open Wednesday through Sunday and offers guided tours in several languages. Visitors should allow adequate time to walk through the compact spaces and prepare themselves emotionally for the content within.
Many prisoners carved or wrote messages, names, and symbols into the cell walls that remain visible today. These traces offer a direct connection to the personal stories of people who were detained here.
