The tunnels began as Greek-era tuff quarries, cut to supply the soft volcanic stone used to build the city above. The Romans later adapted the same excavated spaces into a vast aqueduct and cistern system, channelling water through the city for centuries — a use that continued in various forms into the modern era.
During the Second World War, the network took on a third life as an air-raid shelter, and parts of the route still show what people left behind: makeshift beds, graffiti, and household objects abandoned mid-use. A separate branch of the guided route leads through a private apartment building into the remains of a small Roman theatre, discovered when the space beneath a Naples home was investigated.
Inside
What to see
- The Roman aqueduct cisterns, carved from the same volcanic tuff the city itself is built from
- Wartime shelter remains, including beds and personal items left from air raids in the 1940s
- A candlelit narrow-passage section, part of the guided route through the tightest original tunnels
- The Roman theatre fragment, reached via a passage through a modern apartment building above
Practical
Good to know
- Visits are guided only, at set times through the day — you cannot explore independently.
- Some sections are genuinely tight, navigated single-file and partly by candlelight; this is not a good fit for anyone with significant claustrophobia.
- Comfortable shoes are worth wearing — the surfaces underground are uneven stone, not finished flooring.

FAQ
Common questions
Is it suitable if I'm claustrophobic?
Some sections are genuinely narrow and navigated by candlelight — worth asking staff in advance if tight spaces are a concern.
Can I visit without a guide?
No — all visits run as guided tours on a fixed schedule; independent exploration isn't permitted.
How long does the tour take?
About ninety minutes, covering the aqueduct system, wartime shelter remains and the Roman theatre fragment.
What should I wear?
Comfortable, sturdy shoes — the underground surfaces are uneven stone rather than finished flooring, and it stays cool year-round.
