One of the groups of witnesses to the crimes perpetrated at the concentration and extermination camp Auschwitz were British prisoners of war who were forced to work on the construction of the IG Farbenindustrie factory. The building site was located in the immediate vicinity of the Auschwitz III-Monowitz camp and a few kilometers from the Auschwitz I main camp. British prisoners of war were also employed at the mines in Libiąż and Jaworzno, where Auschwitz sub-camps were later established. Dr Piotr Setkiewicz, head of the Auschwitz Museum Research Centre, talks about the history of British POWs near the Auschwitz camp.
