Underground Naples
Beneath the vibrant streets of Naples lies an ancient and mysterious world waiting to be discovered. Napoli Sotterranea, or Underground Naples, offers a fascinating journey through centuries of history, from Greek and Roman aqueducts to WWII bomb shelters. This expert guide provides all the essential information for planning your visit to Napoli Sotterranea, ensuring you experience the best of this subterranean wonder.
A Journey Through Time: What to See
Greek and Roman Aqueducts
Begin your descent with a journey down 136 steps into ancient tuffaceous cavities built by the Greeks in the 4th century BC. These cavities served as underground water tanks for 23 centuries, a testament to the engineering prowess of the ancient civilizations. The well-lit paths reveal an expansive network, though some areas require navigating by candlelight, adding a sense of adventure and mystery.
WWII Shelters and Artifacts
During World War II, the tunnels of Napoli Sotterranea provided refuge for thousands of Neapolitans during air raids. Today, visitors can explore these shelters and panic rooms, where traces of human history remain—clothes, utensils, supplies, and even toys left behind by those who once sought safety here. This part of the tour offers a poignant glimpse into the lives of wartime survivors.

Hypogeum Gardens
One of the unique features of Napoli Sotterranea is the Hypogeum Gardens. These underground gardens thrive in an environment shielded from pollution, acid rain, and human interference. The flourishing plants in this subterranean oasis create a surreal and peaceful atmosphere, a stark contrast to the bustling city above.
Roman Theater and Summa Cavea
Discover the remains of a Roman theater, hidden beneath a typical Neapolitan house. A hatch opens to reveal the ancient theater where Emperor Nero had a private dressing room. The Summa Cavea, a recent addition to the tour, showcases a permanent exhibition of ‘Scarabattoli,’ intricate handmade sculptures displayed in glass cases, offering a glimpse into the artistic heritage of Naples.

What Not to Miss
The Greek Roman Aqueduct
After descending 136 steps, you will find yourself in the Greek Roman Aqueduct. Initially well-lit, some parts are too dark, requiring a candle or flashlight. The narrow corridors of the aqueduct offer a special experience, though not recommended for those with claustrophobia.
Roman Theater
A highlight of the Napoli Sotterranea tour is the visit to a Roman theater. This hidden gem is accessed through a typical Neapolitan house and offers a glimpse into ancient Roman entertainment and architecture.
Summa Cavea
Recently expanded, the Summa Cavea is part of the Roman theater featuring ‘Scarabattoli,’ beautiful handmade sculptures in glass display cases. This area adds an artistic dimension to the historical exploration of Napoli Sotterranea.
