    History of the Spanish Quarters Underground

    Volcanic tuff stone walls in underground Spanish quarters.

    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.

    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.

    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.

    We were through the line quickly at Peastum - it was a beautiful! Pompeii was another story as we were not aware of the 1st Sunday of each month being a Museum holiday where everyone egts in free. We waited in line for 2 hours because the "voucher" did not count as a printed ticket aloowing us immediate acccess, and then we were smooshed in through the gates by hoards of people trying to get in before it closed.

    Easy to use and good value for site entry and getting around. Got on train from Sorrento to Herculaneum not knowing it only stopped a few times a day. Went through to Naples and easily caught the train to Herculaneum without extra cost or trouble. 😂
