Guided descent about 40 m below the old city through Greek-Roman aqueduct tunnels, cisterns, World War II air-raid shelters and a Roman theatre cavity.
Napoli Sotterranea is a guided underground tour that starts from Piazza San Gaetano 68 in the Centro Storico of Naples, Campania, Italy. The city rests on soft volcanic tuff, and since Greek times residents have quarried the stone for building, leaving a network of tunnels and cisterns beneath the streets. The tour descends about 40 metres below the old city to explore part of that network.
The route passes Greek-Roman aqueduct tunnels that supplied the city with water for centuries, large cisterns, and narrow passages where guides explain how wells connected homes above to the water system. Chambers used as air-raid shelters during World War II still hold objects and graffiti from that period, which gives the visit a strong human dimension. The tour also reaches a cavity linked to a Roman theatre, hidden beneath the houses of the district.
Visits are by guided tour only, and the full tour lasts about 1.5 hours. English tours run several times a day, commonly around midday, early afternoon and early evening, while Italian tours are held in the morning; times change seasonally. Passages can be narrow and damp, and the temperature stays cool all year, so a light layer is useful. Visitors who are uneasy in tight spaces should note that some sections are confined.
Crowds are heaviest in summer and at weekends, when tours fill up, so advance booking is advisable. An afternoon tour fits well after lunch in the historic centre, since the entrance is a short walk along Via dei Tribunali from Dante metro station on Line 1. The meeting point is also close to San Lorenzo Maggiore and Via San Gregorio Armeno. Adult tickets cost about EUR 15, with reduced prices for ages 5 to 17 and free entry under 5.
