Underground Naples : info and guided tour

Introduction to Underground Naples

Underground Naples refers to the network of underground passages open to visitors beneath Naples’ historic center, near Piazza San Gaetano. The tour takes you down into ancient spaces carved into volcanic tuff, where you discover another side of the city, quieter and more layered, far from the bustle of the streets above.

This site is famous for its galleries, cisterns, and passageways that bear witness to the historic use of Naples’ underground. Here you can see traces from different eras, with spaces originally fitted out for water supply and later reused over time. The appeal of the place lies as much in its history as in its tangible expression of the underground city.

The route highlights the volcanic rock, old masonry, and irregular volumes carved into the stone. Some areas recall the excavation and underground construction techniques specific to Naples. Together, these features give a clear idea of how the subsoil was exploited, transformed, and preserved within the urban fabric.

Underground Naples also draws visitors because of its special atmosphere, at the crossroads of archaeology, urban memory, and geology. The visit reveals emblematic spaces such as narrow galleries, former water reservoirs, and underground areas linked to the daily life of the city. It is a place appreciated for understanding Naples from below.
