"Pawiak" was the largest prison in Warsaw, where the Gestapo and the security service imprisoned Polish patriots who fought against the German occupation from October 1939 to August 1944.
Krystyna Usarek and her parents were imprisoned here, as well as Wanda Kiedrzyńska and Joanna Muszkowska-Penson - later these three represented Poland in IKR.
It is estimated that around 100,000 prisoners passed through the Pawiak in 1939–1944. 37,000 were murdered as a result of executions or murdered during interrogation or in prison cells. 60 thousand of them were transferred to other prisons, deported to concentration camps and to forced labor in Germany.
14 transports left Warsaw to the camp in Ravensbrück, the last of which on July 30, 1944, with about 400 women.
Memorial plaques that the survivors have placed in the prison yard commemorate deportations to various concentration camps.
