A fascinating and mysterious place. The guide was young and knowledgeable, and explained everything perfectly. Unfortunately, by law, you’re not allowed to take photos or videos, but it’s a place you’ll remember forever!

The young man who guided us was very clear and engaging. The description of the fabulous nativity scene in the sacristy of the basilica was delightful. The catacombs were a source of interest for my wife and me in terms of the past and present history of the district. Special thanks for the commitment of the young people from the La Paranza cooperative.

I visited underground Naples in the Spanish quarters with my family and a nice group of other tourists. Giulia, our young but well-prepared guide, took us through the narrow underground passages, introducing us to a reality of Naples that we did not know, with anecdotes and curiosities that made the tour very interesting and lighter than expected. Perhaps also thanks to the presence of O' Munaciello??? Highly recommended!

History of the Spanish Quarters Underground

4th century BCE

⚒️Greeks establish Neapolis and quarry volcanic tuff stone from the area now known as the Spanish Quarters for construction. These quarries form the foundation of the underground network in this district.

Roman Era (1st century BCE – 5th century CE)

🚰The Neapolis Aqueduct is constructed, using the tuff quarries and tunnels to transport water across the city. This sophisticated system supplies homes, public baths, and fountains, playing a crucial role in urban life.

Middle Ages (5th – 15th century)

🏙️The aqueduct remains in use but sees gradual neglect due to invasions and changes in urban infrastructure.

⚠️Underground spaces begin to collapse in some areas, while others are repurposed for waste disposal and storage.

16th century (Spanish rule)

🪖The Spanish Quarters (Quartieri Spagnoli) are developed to house soldiers. Urban expansion overlays the existing underground system, connecting homes and structures to the ancient aqueduct network.

18th – 19th century

🏗️As Naples’ population grows, underground spaces beneath the Spanish Quarters are further utilized for cisterns and waste management.

⛔Portions of the aqueduct are decommissioned due to contamination concerns, but parts remain active.

World War II (1939–1945)

💣The underground quarries and aqueduct chambers serve as air raid shelters, offering protection during bombings.

🖌️Residents leave some of their everyday items and art behind, providing a snapshot of wartime life underground.

Post-War Era (1950s–1970s)

🚧The underground network is largely abandoned, and some sections are sealed off due to safety concerns. However, local historians and explorers are beginning to rediscover its significance.

Modern Era (1980s–present)

🔎Restoration efforts uncover the extensive Neapolis Aqueduct beneath the Spanish Quarters.

📐The site becomes part of the Naples Underground experience, showcasing the aqueduct's engineering, tuff stone quarries, and WWII shelters. Tours highlight the distinct role this underground network played in Naples’ water supply and resilience.

Visitor tips

Time your visit wisely: Weekday mornings often have fewer visitors, allowing for a quieter, more immersive experience.
Ask about special exhibits: Occasionally, temporary exhibitions or multimedia presentations are hosted underground. Check ahead to see if there’s something extra to enjoy.
If you’re in the mood to shop after your tour, take your pick from the boutique stores on Via Toledo or the open-air market stalls of La Pignasecca.
Sfogliatella, a beloved symbol of Naples, is a sugar-dusted, ricotta-filled pastry infused with vanilla, cinnamon, or Sorrento lemon. Pintauro Pasticceria, right near Via Toledo, is a top destination to enjoy this iconic treat.
The underground paths can be uneven and slightly damp, so sturdy, non-slip footwear is a must for navigating the tunnels safely. Temperatures underground can be cooler than above ground. A light jacket or sweater will keep you comfortable.
