The fortress had also served as an Oflag in World War I.

Camp history
In June 1940 British, Belgian, Dutch and French senior officers and a small number of orderlies were transported to Mainz from transit camps in France and Belgium after the end of the Battle of France. In June 1942, all inmates were transferred to Oflag XII-A in Hadamar, near Limburg, which was then renumbered Oflag XII-B.
