What in traditional towns is a main square, in Bagno Vignoni is a huge thermal pool, but you can’t jump in there!
The thermal baths of Bagno Vignoni, probably well known even in Etruscan times, were definitely enjoyed by the Romans, who consecrated these waters to the Nymphs (as a plaque located under the arcade of the church of Santa Caterina testifies).
Thanks to their close vicinity to the Via Francigena and to their curing properties, these baths grew in importance during the medieval period. Bagno Vignoni became a halting and refreshment point for the numerous pilgrims who traveled the Francigena on their way to Rome. The spa also became a popular resort for dignitaries like Lorenzo il Magnifico and Pope Pio II Piccolomini.
