Château de La Follie in Écaussinnes-d'Enghien, Hainaut, is a 16th-century manor built on the foundations of a 14th-century medieval castle, situated on the banks of the Sennette River. The lordship appeared in 1365 when Englebert d'Enghien purchased La Follie, deriving its name from "follie" meaning leafy shelter. The château's exceptional feature is its octagonal Gothic chapel dedicated to Saint Christopher, featuring a ribbed vault and rare 16th-century stained glass windows—the only complete example preserved in a Walloon castle chapel. Designated as exceptional heritage of Wallonia since 1976, the château hosts an annual classical music festival each July.
