Bring your walking shoes and a light jacket and get ready to head underground! Underneath the streets of Naples lies a labyrinth of ancient aqueducts, catacombs, and bomb shelters. It’s a hidden city worth exploring. Naples has been continuously occupied for over 2,000 years. The current city is like a stone tiramisu, with layers upon layers of history.

There are two competing tours called Napoli Sotterranea. Why? Naples has so much to see belowground, and the name Napoli Sotterranea means simply, “Naples underground.” This first tour, arguably more well-known, starts from the heart of the historical center in Piazza San Gaetano, next to the Basilica di San Paolo Maggiore. The underground tour will take you on a journey through the history of the aqueducts from the Roman times to WWII.
