January 27, the day Soviet troops liberated the surviving prisoners at Auschwitz is now commemorated as "International Holocaust Remembrance Day." From 1942 to 1944, Jews, Sinti and Roma, homosexuals and political opponents to the Nazis from all over German-occupied Europe were brought to the camp and its gas chambers. At least 1.1 million prisoners died at Auschwitz, around 90 percent of them Jewish. The museum on the site of Auschwitz I and II is a UNESCO World Heritage Site.
