Erected in the hamlet of Prelles at an altitude of 1,400 metres, this oratory overlooks and watches over the Durance valley. It resembles a small rectangular niche closed off by a glazed wooden door, in which a statue of the Virgin Mary and a metal cross have been placed. But who was this saint? Known as Saint Ursus in English, he was a monk who was born in Ireland and travelled to this region where his evangelisation and help for the poor left a lasting mark on the population.
