History+
Bitremont's history began in the 12th century as the seat of a seigneury. The estate belonged to families such as Enghien, Argenteau, and Merode. Later, the noble family Visart de Bocarmé acquired the castle. On September 5, 1753, the lordship of Bitremont was elevated to a county for Louis-François Visart. A fire in April 1998 severely damaged the castle's residential building, turning it into a ruin.
