Naples Underground Guided Tour

The city of Naples is built from yellow tuff stone, and the quarries that supplied it left a second city underground. Over the centuries the cavities became aqueducts and cisterns, and in the Second World War they sheltered thousands of people from air raids.

This guided visit leads you down a long staircase into the tunnels, through narrow passages lit by candle at one point, and to the remains of a Roman theatre hidden beneath ordinary houses. Route details may vary by operator and are confirmed with your booking.
