Kasteel de Kerckhove d'Exaerde is a neo-Flemish Renaissance castle built between 1870-1880 by Jules de Kerchove d'Exaerde, who served as vice-president of the Court of Audit and mayor of Steenokkerzeel. The castle features distinctive red brick and sandstone construction with decorative diamond-patterned ornaments, a tower-like central section with decorative spires, and two stories with a high roof. After the owner's death in 1901, the estate served various purposes—as a French convent, restaurant, school colony, and community center—before the municipality acquired it in 1953. Recently restored in 2012, the castle now houses nine social apartments while retaining heritage trees including ancient beeches and horse chestnuts from the original landscape.
