Bomal Castle, 18th-century château in Bomal, Belgium.

Bomal Castle is an 18th-century manor house standing in the Walloon region of Belgium and designed with classical architectural details. The building is surrounded by gardens and features symmetrical windows along with a central entrance on its main front.

The castle was built in 1774 and marks the shift from fortified defensive structures to comfortable residential homes during the late 18th century. This transformation shows how the needs of Belgian noble families changed during this period.

The building displays French design influences typical of Belgian noble residences from its era. Its style reflects how wealthy families in this region chose to present themselves through their homes.

The castle is a private estate and cannot be visited; its entrance gates are at no. 4 rue d'Izier. The building is visible from the rue de Liège (national road 86). The municipal park below the high limestone wall, along the Aisne, is open to the public.

The rocky hill beneath the castle belongs to the Calestienne limestone region and is listed as a site of great biological interest; the woods on it are part of the private estate. The grounds also hold two facing outbuildings from the late 19th century.
