Exploring the Depths: Best Things to Do in Underground Naples

You can reach hallowed graveyards and wartime bunkers that provide a more profound narrative by exploring Underground Naples. This underground realm is only one of many unique and memorable things to do in Naples.

Subterranean Naples: What Is It?

Underground Naples is a complex network of caverns, aqueducts, tunnels, and chambers carved over 2,400 years ago. Initially created by the ancient Greeks, it was later expanded by the Romans with secret corridors and a sophisticated water system. During World War II, these underground spaces became lifelines, serving as protective air raid shelters, hidden cellars, and vital escape routes that safeguarded countless lives and stories of resilience.

In 2023, Naples' Capodichino Airport served nearly 12.4 million passengers, with direct flights connecting to 113 destinations across 34 countries, enhancing accessibility for tourists wishing to explore the city's underground heritage. For a more thorough experience, combine this with a trip from Naples to Pompeii and Mount Vesuvius.
