The pretty Saint-Trémeur chapel, with its typical rectangular floor plan and bell tower accessible via an external staircase, probably dates from the 17th century or the 18th century. It is associated with a fountain that you can see below and a cross probably dating from the second half of the 19th century. Bevelled and set in a boulder, it stands at the crossroads of two roads, on an altar-type base that is quite common in the Morbihan.
Probably built by a lord, whose unidentified coat of arms appears on the segmental arch door of the north door, the chapel is lit only by a small segmental-arched window to the south and the main window to the east. The stained-glass windows were restored in 2025 with the help of the Saint-Trémeur village association. Inside, the building still has its flagstone floor and old granite altar, hidden by a late 18th century altarpiece.
Most of the statues disappeared following a theft in 1968: one of Saint Trémeur and a Virgin and Child from the 16th century, a Saint Avertin and a sculpted group of Saint Trémeur and Saint Tréphine, his mother, from the 17th century. They demonstrate how old religious observance is on this site, as do the fragments of a 15th century bishop that escaped the theft. Today, a 17th century Saint Trémeur and a late 18th century Saint Isidore sit either side of the altar.
