Auschwitz-Birkenau Concentration Camp

Auschwitz-Birkenau Concentration Camp was a large subcamp of Auschwitz Concentration Camp, principally for direct genocidal killing in gas chambers, but also for Nazi medical experiments. As opposed to other extermination camps such as Treblinka, it did have substantial barracks facilities and housed slave laborers as well as experimental victims, but was still principally a killing facility.

The gas chambers used Zyklon B, a hydrogen cyanide preparation, rather than the carbon monoxide of other facilities.

Experiments there were notably performed by Josef Mengele.
