Kasteel d'Overschie, also known as Kasteel de Vorst, is a neoclassical castle with neorococo embellishments located in Grimbergen. Built around 1904 by architect Octave Flanneau on foundations from an 1803 manor house, the structure displays symmetrical composition with decorative window frames, leaded windows, and ornamental ironwork. The 42,700-square-meter estate features a distinctive spoon-shaped pond, serpentine water features, formal gardens with specimen trees, and a decorative iron gate, remaining as a private residence surrounded by modern residential neighborhoods.
