Nestled at the foot of Mount Aiguille, the Chapel of Trézanne offers a magnificent view of this majestic mountain, overlooking it more than 1000 m. This small Romanesque chapel is characterized by its thatched roof which was rehabilitated in 2001 and recently renovated. Before the eighteenth century, the thatched roofs were numerous in the Trièves: they were gradually replaced by tile roofing, notably because of the fires.
