Auschwitz II-Birkenau was a Nazi concentration and extermination camp located in Poland during World War II. Established in 1941, it became the largest camp in the Auschwitz complex, designed primarily for the mass murder of Jews as part of the Holocaust. The camp featured gas chambers and crematoria, where countless lives were tragically lost. The camp was also used for forced labor, with prisoners subjected to inhumane conditions. It housed various groups, including Polish political prisoners, Roma, and Soviet POWs. Today, Auschwitz II-Birkenau serves as a memorial and museum, educating visitors about the atrocities committed there.
