Lanmérin – Chapel, Roman Bridge and Bocage Landscape

Lanmérin brings together cultural and historical landmarks with an agricultural bocage landscape. The town’s history ranges from a Gallo-Roman bridge and a chapel and manor house to a church whose construction history spans several centuries. There are also traces of a grain mill and a spring with a clearly traceable flow of water. If you would like to compare architectural styles and different historical periods on your trip, the town offers several specific points of interest.

Chapel and Manoir de La Salle

The Chapelle Saint-Jérôme de La Salle was built in 1536 at the behest of the lords of the Lagadec family; it has been designated a Monument historique since 1930. The two dates represent different aspects: 1536 marks its construction, while 1930 marks its designation. The Croix de la chapelle de La Salle dates from the 16th century and is made of non-monolithic rose granite, meaning it is not carved from a single block of stone. It stands within the chapel’s enclosure, which is planted with chestnut trees.

The Manoir de La Salle is probably dated to the first quarter of the 15th century and is probably attributed to Huon de La Salle. Its architectural features differ from those of the chapel: it retains a round-arched entrance portal as well as windows with mullions and crossbars. The mullions divide the windows vertically, while the crossbars divide them horizontally. Whereas the chapel is precisely dated to 1536, the dating of the manor house is explicitly only a probable attribution.

Roman Bridge, Mill and Spring

The Pont gallo-romain sur le Guindy dates from the 1st or 2nd century and originally lay along the route of a Roman road. In the Mouden district, it consists of two long stones. It thus provides a distinctly earlier historical marker than the buildings from the 15th and 16th centuries.

The Moulin de Rumolin recalls the area’s former grain milling. Two surviving millstones bear witness to this activity; the remains of the miller’s house and the millrace can also be seen. At the Fontaine Saint-Jean, the statue’s location and the path of the water are equally distinctive: a wooden statue of the saint stands in a niche in the wall opposite the washhouse. The spring at the foot of the statue feeds the basin through an underground conduit. The local landmarks thus highlight different details: at the mill, surviving elements of former work; at the Fontaine, the connection between the statue, spring and basin.

Church and Rural Surroundings

The Église Saint-Mérin dates from the 17th century and was partly rebuilt in the 18th century and again at the beginning of the 20th century. Its history therefore encompasses several construction phases. The bell tower has a balustrade; the access staircase is built into the thickness of the supporting wall. In other words, the staircase is integrated into the wall rather than being described as an externally attached structure.

The landscape also shapes Lanmérin: most of the area consists of farmland, and the work of farmers and livestock breeders shapes the bocage landscape. Both individual buildings and the agricultural surroundings are therefore part of the destination’s character.

Routes and Walks

The 68-kilometre Circuit du Trégor Côte d’Ajoncs passes through Lanmérin. A 2022 tourism guide describes the route as accessible year-round; check the route details again before your trip. The Boucle par Argas answers a different planning question: it is an easy walk, suitable for beginners, families and occasional walkers. The Circuit is notable for its total distance, while the Boucle is notable for its easy level and the stated target group.
