The main concentration camp of Mauthausen was located in Upper Austria and therefore has the highest number and concentration of sub-camps and places related to the Nazi instruments of oppression. The first sub-camp of Mauthausen was begun in December 1939, just 5 km from the main camp in Langenstein (Gusen I concentration camp), further sub-camps were later established for armament production and other forms of forced labour. Furthermore, there were several work commandos working in the immediate area around the camps, such as felling wood in Königswiesen.
