I haven’t been in Auschwitz, but I have heard the testimonies.
Auschwitz has become the universal symbol of mass murder of innocent civilians. Out of the 1.5 million people who were deported to Auschwitz during the war, 1.1 million were murdered. Primarily Jews, but also Sinti, Roma, homosexuals, and political prisoners. Most were sent straight to the gas chamber, and others died from hunger, illness, exhaustion, or were executed.
