Underwater Museum and Knowledge Awareness Centre


In 2020, Greece inaugurated its first underwater museum off the coast of Alonissos, also known as the "Parthenon of Shipwrecks."
This large ship from around 425 BC was carrying thousands of wine amphorae from Peparithos (now Skopelos) and Mendi (Chalkidiki) when it likely encountered a storm and sank.
The thousands of intact amphorae covering the seabed around the wreck provide an remarkable glimpse into the size and shape of the ancient merchant ship. It was discovered by a fisherman from Alonissos in 1985 at a depth of 28 meters. (See also the books section). Visitors have the opportunity to explore the underwater museum during the diving season, which runs until early october. Licensed guides from the diving centers in Alonissos accompany divers to this remarkable historical site. Divers must book their dive at least a week in advance.


For those who cannot or do not wish to dive, there is an opportunity to experience the wreck virtually. The Knowledge Awareness Center in the Old Village has created an exhibition about the ancient wreck, allowing a virtual dive into the region. Opening hours in season 7 P.M. to 10 P.M.
