SS authorities purchased land at the site on May 25, 1938. Managers of the SS-owned firm Deutsche Erd- und Steinwerke(DESt-German Earth and Stone Works), which used concentration camp prisoner labor to extract and finish construction materials at Mauthausen, established next to the “Wiener Graben” stone quarry in 1938, deployed a forced labor detachment from Mauthausen on a daily basis to the Gusen quarries beginning in 1938. Tiring of marching the prisoner detachment three miles to the Gusen quarries, SS authorities authorized the construction of concentration camp Gusen in late 1939.
