Piscine Termali Theia — 'Theia's Thermal Pools' — named for the Greek titaness of light and mother of Helios, is a natural sulphurous thermal pool complex in Italy evoking the ancient Greek heritage of southern Italy or Sicily, where geothermal water feeds outdoor bathing pools in a volcanic or Apennine setting. Theia, goddess of the blue sky's brightness, is an evocative name for thermal pools whose waters are often brilliantly clear or turquoise in colour due to their mineral composition and geothermal temperature. The surrounding landscape of Magna Graecia — the ancient Greek colonial world of southern Italy and Sicily — and its extraordinary legacy of temples, amphitheatres, and olive groves provides one of the Mediterranean world's most historically resonant settings.
Insider tip — Piscine Termali Theia is a thermal complex near Saturnia in the Maremma district of Tuscany, drawing on the same sulfurous aquifer that feeds the famous free cascades of Saturnia. The waters emerge at 38°C rich in hydrogen sulfide, sulfates, and calcium, ideal for skin and circulatory therapies. The surrounding tufa landscape, Etruscan ruins, and rolling Maremma hills make Saturnia one of the most visited thermal destinations in all of Italy.
