Mauthausen concentration camp
Mauthausen was a Nazi concentration camp in Upper Austria during World War II. It opened on 8 August 1938, and was taken over by the Allies on 5 May 1942. It is located on a hill above the market town of Mauthausen (roughly  east of Linz). Mauthausen started as a single camp. However, it gradually grew into a system of many camps, which were all connected to each other. These subcamps were located throughout Austria and southern Germany. In total, about 190,000 people were imprisoned in the Mauthausen camp complex. Of these, at least 90,000 died.
