Temple construction in the 2nd century on the summit of the Puy de Dôme. The Temple of Mercury, built on the summit of the Puy de Dôme, was one of the largest mountain sanctuaries in Roman Gaul. It could be seen from a great distance, including from the city of Augustonemetum, present-day Clermont-Ferrand. The Via Agrippa, a highway from Lyon, the capital of Gaul, to Saintes on the Atlantic, allowed travelers to reach the shrine via the pilgrimage center at the Col de Ceyssat.
