Dachau is the name of a Nazi concentration camp, constructed in a disused gunpowder factory and completed on March 21, 1933. Although Dachau was not the first Nazi prisoner camp, it was the first concentration-style camp after which all subsequent concentration camps were modelled. Together with the much larger Auschwitz, Dachau has come to symbolize the Nazi concentration camps to many people. The camp lies near the medieval town of Dachau, outside Munich.
