Lanmérin brings together various traces of its history: a chapel dating from the 16th century, a manor house dating to the Middle Ages, a Roman bridge, and evidence of mills and water use. The surrounding bocage countryside is predominantly agricultural. Visitors interested in architecture and rural heritage will find a range of subjects to explore during their stay—from the dates of historic buildings to the details of their construction.
Chapel, Cross and Manor House
The Chapelle Saint-Jérôme de La Salle was built in 1536 at the behest of the lords of the Lagadec family and has been listed as a Monument historique since 1930. The two dates mark different milestones: 1536 is the year it was built, and 1930 the year it was listed as a historic monument. The Croix de la chapelle de La Salle also stands within the chapel’s enclosure, which is planted with chestnut trees. The 16th-century cross is made of non-monolithic rose granite, meaning it was not carved from a single block of stone.
The Manoir de La Salle was probably built by Huon de La Salle in the first quarter of the 15th century. It retains a round-arched entrance portal as well as windows with mullions and transoms. These terms describe the windows’ layout: a mullion divides them vertically, while transoms divide them horizontally. The manor house’s estimated date and architectural details thus differ from those of the village’s later-dated buildings.
Bridge, Mill and Spring
The Pont gallo-romain sur le Guindy dates from the 1st or 2nd century and originally stood along the route of a Roman road. At the hamlet of Mouden, it consists of two long stones. Its history therefore encompasses both its early connection to a Roman road and a specifically described construction. This offers a different perspective on the village from the histories of the chapel and manor house: here, the focus is on its age and original road alignment.
Two grain millstones remain at the Moulin de Rumolin as evidence of its former activity. The remains of the miller’s house and the millrace can also be seen. The millstones, house remains and channel point to different aspects of milling: grinding grain, the miller’s building and the flow of water.
The Fontaine Saint-Jean illustrates another link between a structure and water. 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 channel. The statue, spring, channel and basin thus form a connected arrangement, while the washhouse opposite provides another point of reference.
Church and Countryside
The Église Saint-Mérin dates from the 17th century and was partly rebuilt in the 18th century and again in the early 20th century. Its bell tower has a balustrade; the access staircase is built into the thickness of the load-bearing wall. The church’s history therefore includes not only its original date but also its later construction phases.
Most of Lanmérin consists of farmland. The work of farmers and livestock breeders shapes the bocage countryside, adding a rural perspective to the area’s architectural history. If you would also like to include routes in your travel plans, you can consider two options described in different ways: the 68-kilometre Circuit du Trégor Côte d’Ajoncs passes through Lanmérin. A 2022 tourism guide says it is accessible year-round; check the route details before setting out. The Boucle par Argas is an easy walk for beginners, families and occasional hikers. This allows you to factor in the Circuit’s length and, separately, the walk’s difficulty rating when making your choice.
