Terme dell'Osa, Thermal spring in Fonteblanda, Orbetello, Italy
The natural spring releases mineral-rich waters with high concentrations of sodium, chlorine, calcium, and magnesium at different temperatures throughout the site.
During the 14th century, Siena acquired this thermal bath, which appeared in records as 'Balneum Caldanellarum' and later in 1430 as 'Bagno de le Caldane'.
The thermal waters represent a continuation of ancient Roman practices, where communal bathing served both health and social functions in Italian society.
Currently closed to public access due to safety and hygiene concerns, with several unsuccessful restoration attempts since the 1970s.
Doctor Deirnich from Orbetello Hospital analyzed these waters in 1786, naming them 'Probatica Piscina' for their effectiveness in treating skin conditions.
