Napoli Sotterranea

Napoli Sotterranea preserves a network of cavities beneath the historic centre around Piazza San Gaetano. Ancient quarrying, water storage and wartime shelter have each left traces in the volcanic tuff below the city.

Why it matters

The underground spaces connect the materials of Naples's buildings with the infrastructure that supported urban life. Extraction of tuff created cavities subsequently adapted for water management, revealing how one practical use could give rise to another.

What to notice

Cisterns and connecting passages preserve the scale of the hydraulic system. Waterproof coatings recall the need to contain water within porous rock. Other spaces carry evidence of their use as air-raid shelters during the Second World War. Remains of the ancient theatre beneath buildings near Via Anticaglia add a different archaeological layer to the surrounding area.

Context and history

Greek quarrying was followed by Roman development of water infrastructure. Later conduits and changing urban needs repeatedly altered the underground network. The replacement of older water systems left spaces available for other uses, including wartime refuge. Their recovery and interpretation have made the relationship between the visible city and its subsoil an important part of Naples's cultural history.
