If you’re wandering through the historic streets of Naples and wonder what stories lie beneath your feet, this Naples Underground Spanish Quarters tour might just be the highlight of your trip.

Your adventure begins at Vico S. Anna di Palazzo 52, where you’ll meet your guide and start the journey into Naples’ underground world. The tour lasts about an hour, during which you’ll explore two main sites: the ancient Neapolitan aqueduct and the WWII bomb shelters.
Napoli Sotterranea, the first stop, reveals a complex network of tunnels originally created to supply water to the city. These aqueducts, carved into rock, showcase impressive engineering feats from centuries past. You’ll walk through narrow passages—reviewers mention the tunnels can be “very narrow,” requiring some sideways crawling or on your knees—so comfortable footwear and a sense of adventure are recommended.
The second part takes you into WWII air raid shelters used by locals during the bombing campaigns. Here, you’ll see how the city adapted its underground spaces for survival, with stories that bring a human element to the concrete and stone. One reviewer mentioned, “it’s a fascinating look at life during bombing raids,” highlighting the emotional impact of this segment.
Guides like Agostino and Massimo receive consistently high praise for their storytelling.
