Bagno Vignoni is a small village in the heart of the Val d'Orcia, among the hills of Siena, which has 30 inhabitants. Stone houses, flowered balconies, small squares, artists and craftsmen's shops create an extraordinary architectural ensemble that makes it one of the most beautiful in the world. The rectangular basin, of sixteenth-century origin, collects the water that flows at a depth of 1000 meters from a stratum of volcanic origin. The temperature of the water, fixed at 52 degrees, creates extraordinary scenic effects especially in winter when it comes into contact with cold air. Since the time of the Etruscans, the baths of Bagno Vignoni have been frequented by illustrious people and many artists who had chosen the village as a holiday resort, including Lorenzo de' Medici and Santa Caterina da Siena; the loggia built on the pool is dedicated to the saint.
