Overview

Beneath the bustling streets of Naples lies a hidden city, a labyrinth of tunnels and chambers that tell the story of millennia. Known as Underground Naples (Napoli Sotterranea), this subterranean world began in the 4th century BCE when ancient Greeks quarried volcanic tuff to build Neapolis. The Romans expanded the network, creating aqueducts and cisterns to supply the city with fresh water.For centuries, these underground spaces served as a vital part of Neapolitan life. During World War II, the tunnels were used as air-raid shelters, protecting citizens from devastating bombings. Today, visitors can explore this hidden city, walking through narrow passages and vast chambers, witnessing the ingenuity and resilience of past generations.The Napoli Sotterranea tour, starting from Piazza San Gaetano, descends 136 steps to a depth of 40 meters. Here, you can see the ancient Greco-Roman aqueduct, Roman theater ruins, and artifacts from WWII.Other underground sites include the Bourbon Tunnel and the Catacombs of San Gennaro and San Gaudioso, each offering a unique perspective on Naples' layered history. Exploring Underground Naples is a unique experience, revealing a hidden side of this vibrant city.
