A gas chamber and crematorium complex under construction at the Auschwitz-Birkenau killing center in German-occupied Poland, March 1943.
This image shows Crematorium IV at the Auschwitz-Birkenau killing center. This crematorium complex included an undressing room, gas chambers, and crematoria furnaces. In March 1943, shortly after this photo was taken, the Nazis began murdering Jewish people in the gas chambers of Crematorium IV. In October 1944, Jewish Sonderkommando prisoners staged a revolt and set fire to this building.
