Kasteel van Reet, also known as Laarhof or the castle of 't Laer, is a country house in Reet near Rumst with roots extending to the 13th century. Originally a feudal fortress, it was rebuilt as a mannerist castle between 1649–1651 and enlarged into a baroque pleasure palace in 1714, blending renaissance, baroque, and neoclassical architecture. The castle features a baroque kitchen with Delft tiles, neoclassicist salons, and grounds enclosed by a moat, while the baroque garden redesigned between 1715–1730 later evolved into a romantic landscape park with winding paths and a rare plant collection, protected as a monument since 1974.
