 In the Nazi era, Waldheim prison became notorious as a detention centre for political opponents, convicted for preparation of high treason, undermining military morale or just listening to banned "Feindsender" radio stations.Among the inmates were several resistance fighters like Eva Schulze-Knabe, who was convicted by the People's Court in 1942 and freed at the end of World War II.When the NKVD special camps were handed over from the Soviet Military Administration to the East German government in 1950, numerous NKVD detainees were transferred to Waldheim for further detention and for trial.
