Kasteel van Hoeilaart is a romantically styled castle in Hoeilaart, Belgium, built in 1858 in the park grounds replacing the former castle of the lordship Ter Heyde. Designed by renowned Belgian architect Jozef Claes, who also designed Arenberg Castle, the structure exemplifies 19th-century architectural sophistication. The castle features an adjacent Onze-Lieve-Vrouw chapel and currently houses the town hall. Protected as a monument, the estate serves as a cultural landmark and summer gathering place for the local community.
