Auschwitz I was originally built as a concentration camp with beds, an execution wall, and showers that led to gas chambers and ovens. Auschwitz II (Birkenau) was constructed as a larger death camp where over 1.5 million people were killed between 1940-1945, with facilities to kill 2,000 people at once and only 5 minutes twice a day allowed for bathing. The documents describe the living conditions and mass killings that occurred at the two Auschwitz camps.
