The pretty village of Saint-Oyen nestles on the left sloping banks of the Morel, a tributary of the River Isère, at an altitude of 586m. It is named after its patron saint Eugendus (Oyend in French); this applies for the three villages of Saint-Oyen in the Aosta Valley, Saint-Oyens in the canton of Vaud and Saint-Oyen in the Tarentaise area. It overlooks Aigueblanche basin. Steeped in a rich past and a longstanding tradition in these Alpine valleys, the village boasts two chapels, Saint-Roch and Notre-Dame-du-Puits, and a Baroque-style church (17th century).
