Arbeitsdorf ("work-village") was a Nazi concentration camp in Stadt des KdF-Wagens bei Fallersleben 1942.
With Hitler's approval, Porsche and his business partner Albert Speer set up a factory in Fallersleben, a town 30 miles (48 kilometres) northeast of the city of Braunschweig, and because of the war, all production from this camp was to be used for military purposes only.
In 1942, Porsche and Speer started a project to see how they could use concentration camp inmates for cheaper, and large-scale production of their cars, in order to benefit their industry.
The prisoners of Arbeitsdorf were skilled workforce used for construction tasks, building a casting plant and other facilities and receiving better captivity conditions in return.
