The Auschwitz-Birkenau State Museum (Polish: Państwowe Muzeum Auschwitz-Birkenau) is a museum on the site of the Auschwitz concentration camp in Oświęcim (German: Auschwitz), Poland. The site includes the main concentration camp at Auschwitz I and the remains of the concentration and extermination camp at Auschwitz II-Birkenau. Both were developed and run by Nazi Germany during its occupation of Poland in 1939–1945. The Polish government has preserved the site as a research centre and in memory of the 1.1 million people who died there, including 960,000 Jews, during World War II and the Holocaust. It became a World Heritage Site in 1979. Piotr Cywiński is the museum's director.
