This 13C-16C Gothic church, on the site of a Mosan Romanesque edifice, has a 17C onion-domed bell-tower. The interior has rich furnishings, including a magnificent rood screen from 1531, 16C stalls and a 10C statue of Our Lady of Walcourt in the left arm of the transept. The 13C reliquary cross and 14C silver Virgin Mary in the treasury are particularly noteworthy.
