Château de Bousval, Castle in Genappe, Belgium

Château de Bousval is a castle on rue du Château in Bousval, part of Genappe. It is an L-shaped building: a long seven-bay north wing with rectangular shuttered windows and five dormers, and a shorter west wing of four bays with basket-handle arcades, converted into an orangery probably in the 18th century. A square tower stands at the junction, and a round tower with a slate spire adjoins the north facade.

Construction began in 1567 for a household official in Margaret of Austria's court. Only the original corner tower survives from this early period of the estate.

The castle and its seigneurie passed to the comital van der Stegen family, then changed hands repeatedly before reaching the Solvay family in the 20th century. In 1886 Adolphe Delhaize bought it and lived there until his death on 9 October 1899; his son Maurice occupied it until 1953.

The castle stands at 33 rue du Château, at the southern exit of Bousval village on the road toward the Chapelle du Try-au-Chêne. A white-painted brick wall with a black metal gate and gate pillar runs along the front. The grounds are enclosed by this wall; the gate is the only visible entry point from the street.

The date 1617 is still visible on the roof of the main wing, marking the transformation by J-B Maes, who bought the estate in 1607. The castle later passed to the Solvay family in the 20th century, after belonging to the counts van der Stegen.
