Built on the Chimay Square, in the time of cathedrals, the collegiate church is certainly one of the most remarkable religious buildings in Hainaut Province. This limestone church has a 13th century Laonnois Gothic choir, a 15th century late Hainaut Gothic aisle extended by two chapels — Gothic to the north and Baroque to the south — and a Baroque tower from the first half of the 18th century. The choir is the oldest part of the church. Dated by archaeologists as being from the 13th century, along with a few remains of the Mediaeval wall, the oldest Chimay monument. Open visit (presentation sheet available at the entrance to the collegiate church) or with a comprehensive guide from the Chimay Tourist Office.
All year round, free visit all day except the hours of celebration
