From Myths to Modern Healing: The History of Ischia’s Thermal Waters

The story of Ischia’s thermal waters begins with the Greeks in the 8th century BC, who believed the springs had divine powers.

Temples were built near the springs to honour gods like Apollo, and the waters were thought to heal body and soul.

The Romans took it further, creating public baths for soldiers to recover from battle wounds.

The Nitrodi Spring became famous for its ability to heal and beautify, a reputation it still holds today.

Fast-forward to the Renaissance, when Giulio Iasolino, a pioneering doctor, catalogued the springs and their therapeutic properties, calling them a “gift from heaven.”

Highlight: The Nitrodi Spring is Europe’s oldest known spa, continuously praised for its healing properties for centuries.

Curiosity Corner: Did you know Giuseppe Garibaldi, the legendary Italian general, came to Ischia to heal a battle wound? After his famous clash with the bersaglieri in Aspromonte, he stayed at Terme Manzi in Casamicciola Terme to recover, where even the Forio Brass Band couldn’t resist serenading him despite his wish for privacy!
