Descend 40 metres beneath Naples' streets into a labyrinth of Greek-carved tunnels, WWII air-raid shelters, and ancient cisterns — one of the world's most extraordinary buried cities, explored with a specialist historian.
What to expect
You descend via a narrow 18th-century staircase into a world of Greek-era tuff passages, Roman water infrastructure, and WWII civil-defence bunkers still chalked with wartime messages. Your historian traces 2,500 years of Neapolitan life through the rock itself. The temperature drops to a cool 14°C — a welcome contrast to the street heat. The tour surfaces inside a striking Roman theatre hidden beneath a modern palazzo, a genuinely astonishing moment.
Good to know
The tunnels are mildly claustrophobic in places and involve narrow passages and low ceilings — not recommended for those with severe claustrophobia. Wear comfortable shoes; the ground is uneven. The entrance on Piazza San Gaetano is a 15-minute walk from the Port of Naples or a short taxi ride. Allow 1.5–2 hrs for the private tour.
