This chapel was beautifully restored after the fire in the summer of 2022. This hill offers a lovely view of the Monts d'Arrée.

The chapel originally dates back to the 17th century. A visit is definitely worth it – the view is simply fantastic!

Very beautiful chapel, recently restored after a fire in 2022. The panorama over the entire Monts d'Arrée, the sea and the crests of the Montagnes Noires is magnificent.

Exceptional views from the summit. You can reach the summit by racing bike, although the last part is a bit gravelly.
