Kasteel Cantecroy in Mortsel, Antwerp, is a fortified residence with architectural layers spanning six centuries. First documented in 1289 when members of the Volcaert family served as steward, the castle was acquired and expanded by Willem III van Berthout, who built a keep between 1296 and 1308. A chapel from the 15th century adds spiritual dimension to the complex. In 1550, the Perrenot de Granvelle family purchased Cantecroy and Cardinal Antoine Perrenot de Granvelle transformed it into an elegant country retreat hosting prominent guests including the Counts of Egmont and Horne and William of Orange. Though the city council dismantled many defenses in 1616, Cantecroy has survived as a fortified residence, now accommodating residential apartments alongside dining and event facilities.
