Château de Grune is a fortified manor in Nassogne, Wallonia, with medieval foundations dating to the late 13th or early 14th century, rebuilt in 1613 and again restored in the 19th century. Constructed of sandstone blocks and positioned within an English-style landscaped park featuring rare tree species over a century old, the castle served as the seat of a feudal lordship under the County of La Roche. Severely damaged during World War II, the main structure was restored by the 1950s. Now privately owned and inhabited by the de Ramaix family, the castle has been classified as a historic monument since 1947.
