Set in the lush Vonne Valley between Poitiers and Niort, the Gallo-Roman site of Sanxay was important for its healing waters and as a pilgrimage site from the 1st to the 4th centuries AD. It was excavated by Father Delacroix in 1881.
Remains of a theatre, baths and a temple have been wonderfully preserved at this Gallo-Roman site with a rich history. The theatre could have seated some 6,500 spectators. Originally built in the 1st century, the baths were transformed in the 2nd and 3rd centuries. The three baths of these impressive remains can be discovered by strolling along the walkways. The temple, with its octagonal cella and cross-shaped gallery, was no doubt erected on a Gallic place of worship and is remarkably large.
