The Puy de Dôme sanctuary was serviced by a path that started from the Roman road linking Lugdunum (Lyon) to Mediolanum Santonum (Saintes), at the level of the Ceyssat Pass. There was a secondary town with at least one temple allowing the traveler in a hurry to fulfill their devotion to Mercury without having to climb to the top. A building acting as a road relay is also suspected. There are also traces of an artisanal district around the trachyte quarry which supplied the summit temple with the stone necessary for its construction. Finally, a funerary area is nearby.
