This former seigneurial chapel is dedicated to Saint-Gildas. The building can be dated to the end of the 15th century or the 16th century, with the exception of the west bell tower, which was rebuilt in the 3rd quarter of the 18th century. The Coëtmen family coat of arms can be seen on the bell tower.
In addition to its high altar, which reuses 16th-century panels depicting the Life of Saint Gildas (listed as an object in 1911), the chapel is home to several remarkable statues:
- a sculpted group representing the martyrdom of Saint Apolline between her executioners, dating from the 17th century (listed as an object in 1972);
- a sculpted group representing Saint Nicolas at the very moment of the resurrection of the three children killed and thrown into the salt cellar (listed as an object in 1972)
- a sculpted group dating from the 17th century representing the Trinity: God the Father and Christ and a medallion representing the Holy Spirit in the form of a dove (listed as an object in 2005)
- Saint Éloi with his attributes: horseshoes, anvil and hammer
- a Virgin and Child
There are also wall paintings dating from 1815.
The chapel is open once a year for the pardon.
