What to expect

Into the layers of Naples

Descend 136 steps into the depths of Naples’ underground, 40 meters below the surface, and uncover a hidden world shaped by centuries of history. Explore ancient Greek cisterns, medieval tunnels, and Bourbon-era shelters, once used for water storage and wartime protection. Walk along well-lit pathways to discover the Arianna seismic station, a unique underground greenhouse, and a War Museum that vividly recounts Naples’ wartime past.

Unique underground chambers

Your journey continues to the Roman Theater, where you'll enter a typical Neapolitan home to discover Emperor Nero’s private dressing rooms. In the Summa Cavea, explore a fascinating permanent exhibition of antique nativity scenes alongside remnants of Bourbon-era sewers. Conclude your adventure at the Hypogeum Gardens, an underground botanical project showcasing innovative crop cultivation in the subsoil—a concept that has drawn the attention of researchers and organizations like NASA. This one-hour experience combines history, science, and natural beauty.
