Saint Michel chapel, Lake of Serre-Ponçon
The chapel Saint-Michel, associated with the abbey Saint-Michel (Sacra di San Michele in Italy), was built in the 12th century on a small hill, in the hamlet of Couches. Destroyed in 1692 by the troops of the Duke of Savoy, it was rebuilt in the 17th century. During the construction of the dam in 1961, the destruction of the chapel was planned, but, ironically, its altitude is slightly higher than the height of the lake.
