Saint-Feuillen Collegiate Church

The Collegiate Church of Saint Foillan is a church in Fosses-la-Ville, a town of Wallonia located in the province of Namur, Belgium. While its origins can be traced to a Merovingian monastery, the oldest parts of the present church, the tower and westwork, are from the 10th century. Around 1086, the relics of Saint Foillan were brought to the church and around the same time the monastery was transformed into a collegiate church. An unusual external crypt, the only one of its kind preserved in Belgium, was constructed in the 11th century. The nave and chancel were almost completely rebuilt in 1721–1723.
