What makes Auschwitz-Birkenau historically important?
The Auschwitz-Birkenau State Museum encompasses two main sites three kilometres apart: Auschwitz I, the original concentration camp established in 1940 in a former Polish military barracks, and the vastly larger Auschwitz II-Birkenau, constructed from 1941 as the primary extermination centre. Between 1940 and 1945, the Nazi German regime imprisoned over one million people here — the overwhelming majority of them Jews, along with Poles, Roma, Soviet prisoners of war, and people from across occupied Europe. Approximately 1.1 million people were murdered at Auschwitz-Birkenau, the majority in the gas chambers of Birkenau. The site was designated a UNESCO World Heritage Site in 1979 and is maintained as a museum and memorial.
