Stufe Antiche — 'Ancient Stoves' — is a historic natural geothermal site in Italy, possibly on Ischia or in the volcanic zone of the Campania coast, where volcanic steam vents and sulphurous natural saunas have been used since antiquity for heat therapy and fumigation treatments. The ancient Romans used such natural steam vents (stufe) extensively in their balneological medicine, and the tradition of volcanic steam bathing (sudationes) in natural geological features continues in several locations in Italy's active volcanic zones. The surrounding volcanic landscape, whether the island of Ischia's volcanic gardens or the Phlegraean Fields near Naples, provides an intensely geological setting for this ancient form of natural geothermal therapy.
Insider tip — Stufe Antiche sits within the Campi Flegrei caldera west of Naples, one of Europe's most active supervolcanic zones. Sulfurous vapors and hot springs have been exploited here since Roman antiquity, when the Phlegraean Fields were famed for their healing steam baths. The landscape is otherworldly, with fumaroles, tufa cliffs, and the constant reminder of the volcanic forces beneath your feet.
