Corroy-le-Château Castle (French: Château de Corroy-le-Château) is a medieval castle in the village of Corroy-le-Château and the municipality of Gembloux in the province of Namur, Belgium.

Originally built between 1220 and 1230 by William of Brabant, the castle is one of the best-preserved medieval buildings in Belgium, with gigantic round towers and a moat.

After some eight hundred years in the possession of the descendants of William of Brabant, the last of whom to live there was the Marquis de Trazegnies, a family dispute led to a court ordering the sale of the castle at public auction. In 2008 it was sold to the artist Wim Delvoye, who announced that he planned to turn it into a museum of modern art.[1][2]
