Herewith a photo of the main "piazza" in the village Bagno Vignoni. Not a "piazza" at all but a ancient Roman swimming pool fed by the hot springs of the Val d'Orcia.
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 16th-century origin, which contains the original source of water that comes from the underground 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, Santa Caterina da Siena, Lorenzo the Magnificent and many other artists who had elected the village as 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, you can easily reach the historical centers of nearby Pienza and Montalcino, and the general Val d'Orcia area, including the Park of Mount Amiata.
Bagno Vignoni is also the location where parts of Andrei Tarkovsky's 1983 film Nostalghia were shot.
