Naples is one of the oldest cities in Italy and preserves the world's largest underground paths. From Greek cisterns, and Roman aqueducts, to WWII air shelters. This experience takes you through a hidden gem. Embark on a real archaeological journey in the undergrounds and follow the LAPIS Museum path.

Start from piazza San Gaetano, walk through streets, admire a gothic church, and peer through its glass floor at the remains of a previous ancient mosaic. Next, head down 40 meters through a doorbell in one of the oldest churches in 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.
