The Auschwitz-Birkenau Memorial and Museum, a former German Nazi concentration and extermination camp, has been declared a UNESCO World Heritage Site as a memorial to cruelty, terror, genocide, and the Holocaust.

Today, the buildings of the former German Nazi concentration camp house an iconic museum, visited by more than two million people from around the world each year. The preserved and collected rail sidings and ramps, gas chambers, barracks, photographs, documents, prisoners’ clothes and personal belongings, and barracks furnishings are a staggering testimony to the cruelty of the Nazis.

In Auschwitz, which as of 1942 was the largest of the Nazi German concentration camps and extermination centers, the Nazis exterminated no less than 1.1 million people.
