From the website that details the GR routes of France, in this case the GR®653A Via Aurelia from Menton (Alpes-Maritimes) to Arles (Bouches-du-Rhone) ( or vice-versa if you are headed towards Rome!).
The Via Aurelia, also known as the Aurelian Way, was built in 241 BC by the Roman consul Gaius Aurelius Cotta and was originally a Roman road connecting Rome to Luni in Italy, following the Tyrrhenian coast. As the Romans expanded, additional sections were added to the road. After his victory over the peoples of the Maritime Alps, Emperor Augustus extended the road in 13 BC, from Piacenza in Italy to Arles on the Rhône River. At that time, the construction of the Via Aurelia was of great importance as it shortened the journey between Rome and Hispania. It continues to serve as a vital link for communication, trade, and pilgrimage, following in the footsteps of ancient Romans, medieval pilgrims, and countless others who have traveled along this historic route.
