Kasteel Drietoren in Londerzeel is a neoclassical castle built in 1786 featuring one of Belgium's oldest English-style gardens, originally spanning 4.5 hectares with water moats and ponds. The estate was created by Count Carolus Henricus Gislenus Boot and houses a diverse collection of flora gathered during the de Spoelbergh family's travels. Beyond the main castle, the grounds include a 17th-18th century farm, watermill, garden house, ice cellar, and chapel built in 1884, all set within an expansive park in Flemish Brabant.
