Sorgente Solfurea — 'Sulphurous Spring' — is a natural geothermal spring in Italy where sulphurous water emerges from the volcanic or sedimentary basement in a landscape typical of the Apennine or volcanic zone thermal heritage. Italy's sulphurous springs, distributed across the volcanic zones of Tuscany, Lazio, Campania, Sicily, and along the Apennine mountain chain, have been traditionally sought by bathers since antiquity in the spirit of Roman thermae culture — valued for the intense mineral warmth and distinctive sensory experience that characterises sulfurous immersion. The surrounding Italian landscape, with its deep layers of Etruscan, Roman, medieval, and Renaissance civilisation, gives even modest natural sulphurous springs a profound historical resonance.
