Spanish Quarter Underground tour in Naples

About this activity

Beneath the bustling streets of Naples lies a hidden world, a vast underground network known as Napoli Sotterranea. Dating back to 470 BC, it was originally constructed by the Greeks to create cisterns for rainwater. Over time, the Romans expanded the system, developing an intricate aqueduct that served the city for centuries. Descending into this subterranean city, the humidity rises dramatically to 90%, a stark reminder of how this underground space sheltered countless people during the bombings of the 1940s. With its rich history and fascinating architecture, Napoli Sotterranea offers a unique glimpse into Naples’ ancient past and its vital role in the city's survival and development
