This 13C-16C Gothic church, on the site of a Mosan Romanesque edifice, is topped by an 17C onion-domed bell-tower. The interior has rich furnishings, including a magnificent rood screen from 1531, 16C stalls or a 10C statue of Our Lady of Walcourt in the north transept (one of the oldest in Belgium). The treasury notably displays a 15C monstrance and 14C silver Virgin Mary.
