The name Auschwitz often describes the whole Auschwitz-Birkenau complex. In 2007, its Unesco world heritage listing was changed from ‘Auschwitz Concentration Camp’ to ‘Auschwitz-Birkenau: German Nazi Concentration & Extermination Camp (1940–45) ’. Both Auschwitz and Birkenau are open to the public as the State Museum Auschwitz-Birkenau. The museum’s visitors centre is at the entrance to the Auschwitz site.
