Monuments Terme di Vicarello The thermal waters of Vicarello were known and frequented since antiquity as evidenced by the Etruscan and Greek coins dating back to the 7th century BC found in 1852. From the spring, located about 500 m upstream of the Borgo, the water comes out at a temperature of about 45-50 °C. Its bicarbonate-sulfate-alkaline-earthy composition makes it suitable for sludge and aereosol for the treatment of rheumatism and arthrosis.
