Naples Underground Guided Tour

The Naples Underground Guided Tour takes visitors 40 meters beneath the city to explore a hidden world of ancient Greek cisterns, Roman passages, Bourbon-era tunnels and wartime shelters. Guided by experts, you’ll uncover centuries of history carved into volcanic tuff and walk through narrow tunnels, underground chambers and archaeological remains, including access to the Roman Theater and the Hypogeum Gardens.
This venue is also included in select MegaPass options, making it easy to combine with other top attractions in Naples.

The underground network began with Greek-era quarrying, later transformed into Roman aqueducts that supplied water throughout the city. During the Bourbon period, tunnels were expanded for military and transportation projects. In World War II, these same passageways sheltered thousands of Neapolitans from air raids. Excavations continue to reveal new layers of history beneath the modern streets.

Visitors gain a rare opportunity to explore a multi-layered archaeological system that spans over 2,400 years. The tour blends history, geology and adventure, offering access to ancient water systems, wartime relics, underground gardens and the remains of the Roman Theater. It’s one of Naples’ most unique and educational experiences.
