Naples Underground: 3 Places You Shouldn't Miss | Visititaly.eu

Piazza San Gaetano, 68, 80138 Napoli NA, Italia

Beneath the bustling streets of Naples lies a labyrinthine world stretching back over 2,400 years. Piazza San Gaetano sits at the heart of this subterranean network, built over the ancient Greek agora of Neapolis. The tunnels below were carved from tuff rock, later used as Roman cisterns, wartime air-raid shelters, and clandestine passageways.

This video highlights three unmissable underground sites accessible from this square, likely including Napoli Sotterranea, one of the most extensive and well-documented underground tour routes in the city. Visitors can expect narrow corridors, ancient aqueducts, Greek-Roman ruins, and wartime relics — a genuine journey through layers of civilisation hidden just metres beneath Naples' noisy, sun-drenched streets.
