The documentation focuses on the portrayal of the prisoners, the perpetrators and the regional and economic contexts. Over 100 original objects, countless photographs and documents, eyewitness interviews and animated visualisations tell the history of prisoner forced labour in SS-owned quarries and the arms industry, of ideologically motivated killing actions, and of the expansion and collapse of the Mauthausen camp complex. The different aspects of the camp’s history are placed in the context of the history of National Socialist terror as a whole, as well as in relation to post-war history. At the same time particular consideration is given to the experiences of former concentration camp prisoners.
