Mentioned since 988, Rosans and its church of Saint-Arey certainly look different today, but their antiquity is real. To the west of the village is the Oche district, which is a Gallic name for a cleared area on the outskirts of the village. A "large meadow" and an "orchard", to the west and east show what type of agricultural valuation existed in the Middle Ages. To the east of the village, the clayey hillock of Saint Esteve seems to indicate Saint-Etienne, a long-forgotten church.
