After the war, the Polish government took possession of the Buna-Werke, a chemical factory owned by IG Farben which had previously used Auschwitz prisoners as slave laborers. The chemical industry became the main employer of Oswiecim; in later times service and trade were emphasized. The concentration camps became museums and memorial sites. Currently, about 1 million visitors tour Auschwitz and Birkenau death camps every year.
