Mechelen is a city between Brussels and Antwerp in northern Belgium. Inside the 13th-century St. Rumbold’s Cathedral is an imposing altar and a work by Flemish artist Anthony van Dyck. The attached St. Rumbold’s Tower offers 360-degree views of the city. Deportees to WWII concentration camps were held at Kazerne Dossin military barracks, where a museum and memorial commemorate the Jews and Gypsies who passed through.
