Mauthausen Concentration Camp

Located a couple of hours outside of Vienna, this Nazi concentration camp housed almost 200,000 inmates from all over Europe between 1938 and 1945 when it was liberated by the U.S. Army. The inmates worked under the harshest of conditions at the nearby rock quarry. The granite was used in the construction of Nazi buildings in Germany. The majority of inmates were slowly and ruthlessly worked to death as opposed to extermination camps such as Auschwitz.
