An exciting experience to the underground depths of Naples!

This tour starts from the basement of Palazzo Serra di Cassano, where you'll see some historical finds from WWII, collected in a small museum. The tour then takes you to the old caves of the 16th century, used to extract the tuff stone that helped construct some of the city's buildings.

By going deeper, you will soon see a wonderful water tank from the 17th century, later used during WWII as a bomb shelter, which has been restored. At the end of the tour, take a walk through the Bourbon Tunnel, an ancient underground passage that was built to connect the Royal Palace to Naples' military barracks.
