The term Zone of Interest (German: Interessengebiet) was a term used by the occupying Nazi forces to describe the area around the Auschwitz concentration camp complex reserved for the Schutzstaffel (SS), subject to the administration of the main camp. The zone was created on the land confiscated around the camp, as a 40-square-kilometer (4,000 ha; 15 sq mi; 9,900-acre) zone patrolled by the SS, Gestapo, and local police.[1][2]
