Terme di Petriolo, Thermal bath in Monticiano, Italy
The thermal complex sits along the Farma River in the Valle dell'Ombrone, featuring outdoor pools carved into rocks and fortified stone structures.
The springs attracted Roman citizens, as evidenced by archaeological findings and mentions in texts by Cicero and Martial during the Roman period.
The Renaissance period brought notable visitors including the Medici family, Pope Pius II, and Federico II di Montefeltro to experience the thermal waters.
The thermal waters emerge at 43°C, containing minerals such as hydrogen sulfide, calcium, chloride, and sulfate beneficial for skin and respiratory health.
The site preserves its 15th-century fortification walls and a tower of the Siennese Republic alongside the natural thermal pools.
