Naples Underground

• Explore the Greek-Roman Aqueduct that has supplied water to Naples for more than 23 centuries.

• Take an insight look into the underground chamber used as air raid shelters during World War II. Nowadays, you can still find war relics such as weapons and vehicles left abandoned in the tunnels.

• Walk through the remains of the Roman Theater and visit emperor Nero’s private dressing room.

• Marvel at the newly discovered drain sewers from the Bourbon period, Summa Cavea.  

• Visit Napoli’s Hypogeum Gardens, where plants grow deep under the ground, far from pollution and harmful microorganisms. Students and university researchers use this investigational botany for scientific research.

• Snap some shots while walking through the ancient labyrinth and caves.
• Capture the ruins of the 1st-century theater of Neapolis.
• Photograph the objects and documents from World War II exhibited in the Museo della Guerra.

Although Naples’ castles and museums are impressive, there’s so much more to see if you go underneath its streets. Underground, you can find the real essence of Naples.

• The Bourbon Tunnel: A 14th-century secret royal passage for King Ferdinand II of Bourbon.

• Santa Maria delle Anime del Purgatorio ad Arco: A beautiful church from the XV century where you descend, through a narrow staircase, into an ancient crypt.

• Fontanelle Cemetery: An ossuary, located within a cave in the tuff hillside of the Materdei district.

• The Neapolis Sotterrata: the monumental complex of San Lorenzo Maggiore houses the archeological remains of the Macellum (indoor market) and the Dioscuri temple (open-air theatre)

• Catacombs Of San Gennaro & San Gaudioso: These are underground paleo-Christian burial sites. The most ancient part of the Catacombs of San Gennaro dates back to the II century AD.

• The underground world in Naples is only open to visitors as part of a guided tour. Therefore, it’s highly recommended to book your Naples subterranean tour in advance, especially during high season if you want to guarantee a visit.

• The main underground Naples entrance is located in the left corner of Piazza San Gaetano. The other access point is next to the Bar Gambrinus at the Piazza Plebiscito, roughly 2 km away.

• If you suffer from claustrophobia, this experience might not be suitable for you. With the underground tour of Naples, you’ll be descending 40 meters below the street level and travel through some narrow passages.

• Are you venturing to the underground city Naples has hidden away? Note the temperature is quite low, so it’s advisable to bring a light jacket to use during your visit.
