Sanxay is home to one of the most significant Gallo-Roman archaeological sites in western France. Located near Poitiers, this ancient settlement dates back to the 1st and 2nd centuries AD and was a thriving religious and cultural center. The site spans approximately 20 hectares, with remnants of temples, an amphitheater, and thermal baths that once attracted pilgrims seeking healing waters.

The Temple of Mercury and Apollo is one of the most distinctive structures in Sanxay. Built in an octagonal shape, it was surrounded by a Greek cross-style portico, a rare architectural feature in Roman Gaul. The temple was a focal point for worshippers who believed in the power of its sacred spring, which flowed beneath the cella.

Sanxay also boasts a large amphitheater, capable of seating around 6,500 spectators. This structure was used for gladiatorial combat, theatrical performances, and religious ceremonies. The amphitheater’s design follows the classical Gallo-Roman style, with seating built into the natural slope of the land. Today, it continues to host performances, keeping its historical legacy alive.

Another highlight is the thermal baths, which were an essential part of Roman daily life. The baths were fed by the same sacred spring that supplied the temple, reinforcing the site’s reputation as a place of healing. Visitors can explore the well-preserved remains of these bathhouses, gaining insight into the sophisticated engineering of Roman sanitation and wellness practices.
