Prison camp
At the start of the Second World War, Fort Breendonk was declared the headquarters of the Belgian army. That is why King Leopold III took up residence there from May 9 to 18, 1940. However, after Belgium surrendered, the SS (Schutzstaffel) took over the fort.
The SS was a paramilitary organization within the German Nazi Party and used the fortress as a transit camp and prison for political prisoners. Between September 1940 and August 1944, 3,600 political prisoners disappeared behind bars in Breendonk.
