Heritage: Saint-Oyen

Situated along the road that leads down to Flassin, the building was erected between the 10th and the 11th century. In 1137 it was donated by Amadeus III of Savoy to the Canons of the Gran San Bernardo Hospice, who used it as a stopping station and farmhouse annexed to the hospice.
The building still belongs to the canons of the Gran San Bernardo, and over time, it too became a hospice for wayfarers on their way to the hill.
Today, in addition to the canons, Château Verdun receives individuals and groups interested in periods of study, reflection and rest, as well as scientific meetings.
The square-plan building with its characteristic pitch roof, contains furnishings of considerable interest. The underground rooms have exquisite barrel and cross vaults.

The parish church of Saint-Oyen (the name comes from Sant’Eugendo, a French abbot from the VI century) was presumably founded between 1137 and 1176, the year in which it appears in a Papal Bull by Alexander III as a parish dependent on the bishop. The church was rebuilt in 1820 and renovated in 1990.

The church preserves a beautiful, silver reliquary, which is partially gilded and endowed with set crystals, dating from the XVII century and created by a Swiss artist. It was donated in 1636 to the church by the provost of Gran San Bernardo, Roland Viot.
