Underground Naples

In Naples, you walk on a threshold.
Every step, every square, every alley might conceal an opening below—towards another city: dark, silent, carved into stone and memory.
This is hypogeal Naples, the hidden belly of a metropolis that never ends, made of caves, cisterns, tunnels, crypts, catacombs, and ancient shelters.
Beneath the surface of Naples, it’s not just secrets that lie hidden: the city’s history is etched into the tuff.
A history that begins in the Greek era, flows through Roman engineering, and reaches the 20th century, transforming these cavities into aqueducts, wartime shelters, ossuaries, places of worship, storage spaces, and workshops of life.
