Bagno Vignoni

Bagno Vignoni is a district of the Italian municipality of San Quirico d’Orcia, in the province of Siena, in Tuscany.
The village is located in the middle of the Orcia Valley, close to the Via Francigena. The water that flows in this habitation has been used for thermal purposes since Roman times. In the center of the Borgo there is the “Piazza delle Sorgenti” (Square of the Springs), a 16th century rectangular basin containing a spring of hot and fuming thermal water, coming from an aquifer of volcanic origin. Since Etruscan times and since Roman times, as evidenced by numerous archaeological finds, the thermal baths of Bagno Vignoni have been visited by various personalities, such as Pope Pio II, Caterina of Siena, Lorenzo de’ Medici and numerous artists who chose the village as a vacation resort.
The waters that spring from the thermal basin lead to the steep slope of the natural park of the mills, where there were four medieval mills built in the rocks and which were very important for the local economy at that time, because the thermal spring was constantly active, even in summer, while other mills in the area were at a standstill during the season because of dried up rivers.
