Gęsiówka

Gęsiówka (Polish pronunciation: [ɡɛ̃ˈɕufka]) is the colloquial Polish name for a prison that once existed on Gęsia ("Goose") Street in Warsaw, Poland, and which, under German occupation during World War II, became a Nazi concentration camp.

In 1945–56 the Gęsiówka served as a prison and labor camp, operated first by the Soviet NKVD, then by the Polish communist secret police.

Before the war, Gęsiówka was a military prison of the Polish Army on Gęsia Street (now Anielewicza Street), near the intersection with Okopowa Street and the Jewish cemetery. Beginning in 1939, after the German occupation of Poland, it became a re-education camp of the German security police (Arbeitserziehungslager der Sicherheitspolizei Warschau).

In 1943 it was turned into a concentration camp for inmates from beyond Warsaw and Poland, equipped with a crematorium. The camp, together with the nearby Pawiak prison, formed the backbone of the Warsaw concentration camp complex. Gęsiówka inmates (mostly Jews) included prisoners from Czechoslovakia, France, Greece, Hungary, Belgium and Germany.
