It is estimated that the village of Rosans was founded in the 8th century after the passage of the Lombards and the Sarasins. From the top of its small hill, the village has a good monitoring capacity and a defensive advantage. A rampart that we still use to reach the heart of Rosans, surrounded the village. In the 14th century, the village was invaded by the Provençaux but resisted thanks to its garrison and its ramparts.
