Underground Sicily – Beneath the feet of those who walk across Sicily lies another world. Invisible to hurried eyes, silent even when the surface is alive with voices and traffic, this underground world is as ancient as the island itself. It is revealed in fragments: behind a rusted gate, down a hidden stairway, or along a guided path lit by flashlight. This is Underground Sicily: an island beneath the island, made of tombs, tunnels, crypts, aqueducts, shelters, and secret passages that tell a parallel story—one of great depth and undeniable reality.
Sicily is a land that invites excavation. Its geology—sandstone, tuff, basalt, compact soils—allowed Greeks, Romans, Arabs, Byzantines, Normans, and modern inhabitants to shape the subsoil. Over time, entire secondary cities were born underground, hosting rites for the dead, water routes, religious shrines, or places of refuge. Some of these spaces are older than the cities above them. Others were dug in haste, to protect or to hide. All of them speak of the deep relationship between people and land.
In Syracuse, one of the major centers of underground Sicily, you can visit the Catacombs of San Giovanni, among the largest in the Mediterranean. Kilometers of corridors, burial niches, and ancient Christian tombs are carved into soft rock. Nearby, the Crypt of San Marciano and the Grotto of Santa Lucia offer a glimpse into centuries of layered faith. These sites are open to the public with regular hours and multilingual tours.
In Palermo, the best-known yet most unsettling site is the Capuchin Crypt, where the embalmed bodies of monks and citizens, dressed in period clothing, are lined up in silent corridors. The experience is a chilling yet deeply cultural journey into local conceptions of death and legacy.
In Catania, the city beneath the city comes fully to life. The 1669 eruption of Mount Etna buried Roman Catania, but didn’t destroy it. Under streets and piazzas lie Roman aqueducts, thermal baths, amphitheaters, and early Christian crypts. Some are open to visitors, including the Terme dell’Indirizzo and the fascinating San Gaetano alle Grotte, where the Amenano river still flows underground.
One of the most recommended experiences is the “Catania Underground” tour, bookable online or through tourist offices. These guided visits offer a journey through history, geology, and mystery—all within walking distance of the city center.
Beyond the cities, the underground Sicily of the countryside offers just as much wonder. In the Hyblean mountains, ancient Greek latomie (stone quarries) form surreal landscapes of carved rock and deep green vegetation. At Pantalica, a UNESCO World Heritage Site, over 5,000 tombs are carved into the cliffs of the Anapo valley, reachable by well-marked hiking trails. At Cava d’Ispica, rock-cut homes, churches, and storehouses form an entire carved community. Several sections are visitor-friendly and suitable for families.
Finally, Palermo’s qanāts—Arab-era underground canals—still function today. With professional guides, tourists can descend into these narrow, damp corridors and explore medieval hydraulic engineering still echoing with flowing water.
Travelers who wish to go beyond postcard Sicily should treat themselves to at least one underground experience. These spaces hold centuries of memory, forgotten beliefs, and human resilience—waiting patiently beneath the earth, far from the sun, yet vivid in their truth.
