The Basilica of Saint Maternus (French: Basilique Saint-Materne), also known as the Basilica of Our Lady (Basilique Notre-Dame) is a minor basilica in Walcourt, in the Namur Province of Belgium. According to legend, an oratory was founded here by Maternus of Cologne (c. 285–315), who also carved a Madonna to replace an earlier pagan idol. The church does in fact contain a wooden Madonna, albeit from 950 to 1020, but still one of the oldest preserved Marian devotional statues in Western Christianity. The church was consecrated in 1026. The presence of the Madonna and its allegedly miraculous properties led to the development of the church into a pilgrimage site during the Middle Ages. Subsequently, the church was rebuilt into the Gothic edifice seen today between the 13th and 16th centuries. It contains a decorated rood screen from 1521, donated by Emperor Charles V, and decorated choir stalls from the early 16th century. The church has been damaged by fire and war on several occasions, most recently in May 1940 during World War II. Since 1941 it has been a listed building, and since 1950 classified as a minor basilica.
