Naples: City and Lapis Museum Tour with an Archaeologist

Naples is one of the oldest cities in Italy and preserves the world's largest underground path: between Greek cisterns, Roman aqueducts, and WWII air shelters, 45% of the city's underground is practically empty.

There are different ways to access the underground of Naples, and the experience will take you through a real hidden gem. Embark on a real archaeological journey in the undergrounds (the tour is the LAPIS Museum path).

The tour starts from piazza San Gaetano, the ancient Greek-Roman square, where you'll walk through streets and local culture to understand the "underground cults of Naples." Admire a gothic church and peer through its glass floor at the remains of a previous ancient mosaic.

Next, go 40 meters below the crowds of Naples through a doorbell in one of the oldest churches of the city: Santa Maria Maggiore. The church, built on a Pagan Roman temple dedicated to Diana, still features Roman structures. Keep journeying downwards to see the Greek cisterns carved into the tough stone.
Once you arrive at the lowest point of the route, walk through the tunnels to reach the tanks used for the collection of water in Roman times. This trail was also used in medieval times as a secret passage by the Templar Knights and in 1943 as an airplane retreat. Many of the bathrooms, kitchens, and memorabilia are still preserved to this day.
