The church is composed of a single nave and 4 rows with a vault in tuff. Its bell tower of 10m high was imagined as a defensive tower. In 1575, it served as a shelter during the religious wars. Protestants turned it into a prison and trapped and tortured community leaders saidto be devouts Catholic. Between 1628 and 1637, the church was rebuilt and an additional row was added to accommodate the growing number of Catholics in the Queyras following the revocation of the Edict of Nantes.
