St-Mathurin, Gothic church in Moncontour, France

St-Mathurin is a Catholic parish church in Moncontour, also known as Notre-Dame et Saint-Mathurin. Its light beige and grey stone west facade, rebuilt in 1786 to plans by Antoine Guiber, has a central gable with a large arched window above a dark double door flanked by two niches holding statues, and a lower side wing with a smaller window and doorway. Inside, pointed arches and tall stained glass windows line a wide nave separated from the 1620 south aisle by high columns.

St-Mathurin was built in the 16th century on the site of an earlier church dedicated to Notre-Dame; its oldest parts are the north wall with Flamboyant Gothic windows and a portal. The bell tower was demolished in 1584 and rebuilt by 1587, a south side aisle was added in 1620, and the choir was repaired in 1719. Pillars and roof were raised between 1733 and 1739, and the west facade was rebuilt in 1786 to plans by Antoine Guiber. The church has been classified as a monument historique since 1889.

The church holds six stained glass windows from the 16th century that show religious stories and reflect the craftsmanship of local artisans of that time. These windows remain part of what visitors see when they step inside today.

St-Mathurin stands at the edge of a paved square in Moncontour, in the Côtes-d'Armor department. The west facade, rebuilt in 1786 to plans by Antoine Guiber, faces the square and can be viewed from outside at any time. Inside, rows of wooden chairs rather than pews fill the floor, so seating is not fixed.

The oldest parts of St-Mathurin are the north wall, with its large traceried windows, and a Flamboyant Gothic portal. The axis window is linked to the main window of the Notre-Dame de Folgoat chapel in Paule, dated 1528. Two north-side windows carry their dates: 1537 for the life of Saint Yves and 1538 for Saint Barbara.
