In July 1942 Kazerne Dossin (Dossin Barrack), a former military base in Mechelen, was designated Sammellager, a transit camp for Jews, Roma and Sinti. Between July 1942 and September 1944, thousands of Jews and gypsies were transported from here to concentration camps in Germany. Nowadays, Kazerne Dossin is a Memorial, Museum and Documentation Centre on Holocaust and Human Rights.

The Mons Memorial Museum opened in the spring of 2015. An area of 1,200 m² is devoted to the permanent exhibition, which provides information on the military history of the city of Mons, from the Ancien Régime to the Second World War. The museum invites visitors to reflect on the complex realities of the phenomena of war.
