Built on the hillside on the north-west face of a mound which was a fortified point from the 10th century, the Notre-Dame chapel dominates the channeled course of the Aulne by 35 m. Its oldest parts date back to the beginning of the 13th century. At the time, it was the parish church of a small village established on a nearby hillock of which the place called “Le Vieux-Bourg” remains. The structure of the chapel will evolve over the next 5 centuries according to the different styles of the moment. But despite all these changes, a certain unity emerges which makes this church a small masterpiece of Breton architecture. The church, the triumphal arch, the cross and the ossuary are classified historic monuments.
