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.

The Temple of Mercury on the Puy de Dôme is a Gallo-Roman temple built in the 2nd century on the summit of the Puy de Dôme to replace a 1st century temple. Excavations in 1875 and the early 20th century uncovered the ruins. In the 1st century, the Arverni decided to build a temple to Mercury in their city of Augustonemetum (now Clermont-Ferrand). In the following century, this temple in arkose, which had undoubtedly become too small to accommodate the many pilgrims who visited it, was replaced by a larger and more majestic temple in trachyte.
