The Peristera wreck in Alonissos is Greece’s first underwater museum, featuring a massive Classical-era shipwreck with thousands of amphorae.
Dive Overview
One of the most significant diving developments in Greece in recent years is undoubtedly the opening of the underwater museum at Peristera, near Alonissos.
The site hosts a Classical-period shipwreck containing approximately 4,000 amphorae, making it not only an impressive dive site but also a discovery of major historical importance. Before its discovery, it was widely believed that ancient Greek shipbuilding had not reached the capacity required for vessels of this size.
Access to the wreck is strictly regulated. Divers must book through licensed dive centers with trained archaeological guides, similar to other protected sites in the region and the Peristera Underwater Museum itself.
The dive is typically reserved for Advanced Open Water divers, and a check dive may be required to confirm proper buoyancy control before entering the site.
Entry & Conditions
The wreck is located on Peristera Island, opposite Steni Vala in Alonissos, and is accessible only by boat.
Dive boats moor at designated permanent buoys installed specifically for the museum. Entry and preparation are fully managed by the dive center staff.
The area lies within the National Marine Park of Alonissos, so all local regulations must be respected.
What You ‘ll See
Shortly after descending, the impressive mass of the wreck begins to emerge.
Measuring approximately 30 by 10 meters, the site is covered with amphorae forming a dense and visually striking structure.
During guided dives, access is typically limited to a perimeter route around the wreck rather than direct overhead hovering, minimizing the risk of accidental contact and preserving the site.
In addition to the archaeological remains, the area hosts abundant marine life due to fishing restrictions, offering a combination of history and natural beauty.
Interpretive signage installed underwater enhances the experience, turning the dive into a true “museum visit.”
Important Consideration
- Access only through licensed dive centers
- Advanced certification required (AOW)
- Strict buoyancy control required
- No contact with artifacts
- Boat traffic in the area
Depth Profile
The wreck begins at 22 meters, with its deepest section reaching 28 meters.
Tips for divers
- Ensure excellent buoyancy before entering the site
- Follow your guide’s route strictly
- Keep a safe distance from the amphorae
- Take your time to observe details and signage
- Complete your safety stop at 5 meters
- Stay aware of boat traffic during ascent
