Bagno Vignoni is an Italian village and hamlet (frazione) of San Quirico d'Orcia, situated on a hill above the Val d'Orcia in Tuscany. It is a popular tourist destination and well known for its hot springs.
The ancient village of Bagno Vignoni is located in the heart of Tuscany, in the Val d'Orcia Natural Park. Thanks to the Via Francigena (which was the main route followed by pilgrims in antiquity who went to Rome), these thermal waters were found and have been used since Roman times. At the heart of the village is the "Square of sources", namely a rectangular tank, of sixteenth-century origin, which contains the original source of water that comes from the subterranean aquifer of volcanic origins. Since the Etruscans and Romans - as evidenced by the numerous archaeological finds - the spa of Bagno Vignoni was attended by eminent personalities such as Pope Pius II, Saint Catherine of Siena, Lorenzo the Magnificent and many other artists who had elected the village as their main holiday resort. Characteristic of Bagno Vignoni, besides the thermal waters, are its structure, despite numerous incidents of war, devastation and fires that involved the Val d'Orcia in the Middle Ages, remains essentially unchanged since then. From Bagno Vignoni, one can easily reach the historical centres of nearby Pienza and Montalcino, and the general Val d'Orcia area, including the Park of Mount Amiata.
