Without having the rank of royal road, in the eighteenth century it was an important communication route that connected Aix to Castellane. A battle took place on this Courchon in December 1746, one of the battles of the war of succession of Austria which earned Moustiers the fact to be occupied for a few days by the "pandors" (a word which designated the Austrian soldiers). This historic path, one of the jewels of the Provençal heritage, fruit of the ingenuity and work of the ancients is nevertheless fragile.
