Chapelle Saint-Mathieu de Guidel, Gothic chapel in Guidel, France.

Chapelle Saint-Mathieu de Guidel is a chapel built with a Latin cross shape and a flat chevet, displaying Gothic architectural features from the fifteenth century. The building shows the characteristic stone construction and proportions typical of religious structures from this period.

Construction started in 1487 under Mahé Audren's direction, with backing from the prominent Chefdubois and Rosmadec families in the area. These families were instrumental in funding and shaping this religious site during its creation.

The chapel's name comes from Mahe, the Breton form of Matthew, named in the 1487 foundation inscription. The pardon was revived a few years ago by the association Les Amis de la Chapelle Saint-Mathieu and is held on the third Sunday of September. Each summer the chapel hosts a concert of the festival 7 chapelles en arts.

The chapel sits in the Saint-Mathieu hamlet and comes alive during the annual '7 chapelles en arts' festival, which features musical performances and brings visitors to the site. Finding it requires heading into a quieter, more rural area rather than a central town location.

The granite cross standing between the fountain and the basin was not made for this spot: it was found in a thicket near the German battery of Kerhars, about 2 km north-east of Saint-Mathieu, where it had been thrown. The fountain's pediment still shows the date 1660, now almost worn away.
