LAPIS Museum

Beneath the streets of Naples’ historic center lies another city — silent, carved into stone, layered with centuries of history. The LAPIS Museum, located beneath the Pietrasanta Basilica, is one of the most fascinating ways to explore this hidden dimension.

The route unfolds below the Basilica of Santa Maria Maggiore alla Pietrasanta, within a system of underground spaces that tell the story of Naples’ deep connection with its subsoil.

Here you will find:

ancient cavities dating back to Greek and Roman times
cisterns and hydraulic systems used across centuries
spaces adapted and reused over time

Between water and stone

The name LAPIS refers to stone — the very material Naples is built upon. The experience is enhanced by lighting, installations and storytelling, highlighting the central role of water in the life of the city.

Curiosities to discover

The site lies beneath one of Naples’ oldest religious areas.
It is part of a vast underground network that extends beneath the entire city.
Water systems preserved here were essential for urban life for centuries.

An invisible Naples

Visiting the LAPIS Museum means discovering a hidden but essential side of Naples — a city built layer upon layer, where the underground is as meaningful as what lies above.
