Gaiola Island Island

Website: http://www.ampgaiola.it/

Isola della Gaiola is a tiny rocky islet off the Posillipo headland in the Gulf of Naples, within the municipal boundaries of Naples. It is notable for submerged archaeological remains and for being included in a local marine protected area.

Archaeological evidence on and around the islet shows Roman-period coastal structures and villa remains that have been affected by sea level and coastal processes. The modern designation as a protected underwater area reflects efforts to conserve the archaeological and ecological features.

Sits off the Posillipo quarter of Naples in the Gulf of Naples, immediately offshore from the city and accessible only by boat from Naples’ harbor or nearby beaches.

• Viewing: Protected marine area with visible submerged Roman remains best seen from a boat or snorkel when sea conditions are calm.

What to See#

• Archaeological remains: Covers a small islet and adjacent underwater ruins that include remains of Roman-era structures and villa walls exposed at low tide and beneath shallow water.
• Gaiola Underwater Park: The marine area around the islet is protected as part of a local underwater park that preserves submerged archaeological sites and marine habitats.

Boat access from Posillipo or Mergellina harbors in Naples; the Gaiola Marine Protected Area operates guided visits and has a mainland office for information.

• Book a boat from Posillipo or the Marina Mergellina to see the island's submerged Roman remains from the water.
• Respect signage and private-property lines - parts of the islet are privately owned and off-limits.
• Visit the Gaiola Marine Protected Area office on the mainland to learn about guided snorkeling opportunities.
