Overlooking the Eau d'Heure, the Château de Ham-sur-Heure has two long wings linked by a trapezoidal entrance building. No mention is made of a fortress prior to 1245 and there is no information on its original structure. In 1667, the château was seriously damaged. Louis XIV had ordered the destruction of the keep. In 1689, Marshal d'Humières of France completed the destruction of the towers. Unsurprisingly, the château was considerably remodelled at the beginning of the 18th century at the behest of Count Joachim-Maximilien de Mérode. During the late 18th century, Balthazar-Philippe de Mérode-Montfort entrusted Laurent-Benoît Dewez with further renovation work. The château currently houses some local authority offices and a museum of rural life and handicrafts.
