Oświęcim

Auschwitz or Auschwitz Birkenau German Nazi Concentration and Extermination Camp (1940–1945), was a network of Nazi German concentration and extermination camps built and operated by the Third Reich in Polish areas annexed by Nazi Germany during World War II. It was the largest of the German concentration camps, consisting of Auschwitz I (the Stammlager or base camp); Auschwitz II–Birkenau (the Vernichtungslager or extermination camp); Auschwitz III–Monowitz, also known as Buna–Monowitz (a labor camp); and 45 satellite camps. On January 27, 1945, Auschwitz was liberated by Soviet troops, a day commemorated around the world as International Holocaust Remembrance Day. In 1947, Poland founded a museum on the site of Auschwitz I and II, which by 1994 had seen 22 million visitors—700,000 annually—pass through the iron gates crowned with the infamous motto, Arbeit macht frei ("work makes you free").

In 1947, Poland founded theAuschwitz-Birkenau State Museumon the site of Auschwitz I and II, and in 1979, it was named aUNESCOWorld Heritage Site.
