Dive Site Overview
Beneath the surface of the North Aegean, Fourni unravels an extraordinary tale of maritime history. This area has been a significant crossroads for centuries, evidenced by the no fewer than 62 shipwrecks documented since systematic research began in 2014.
Greece's Ministry of Culture recently transformed parts of this artifact-rich seabed into visitable underwater archaeological sites, marking a notable shift in access for recreational divers. Two primary locations, Akra Fygo on Fourni and Vathylakas on the nearby islet of Thymaina, now allow exploration along designated underwater routes. At Akra Fygo, divers navigate a cluster of seven shipwrecks spanning over a millennium, featuring early Byzantine vessels laden with amphorae and an Archaic-era wreck, one of the oldest identified in the region, carrying Samian transport jars.
A deeper site, "Wreck 15," a 5th–6th century AD vessel, rests at nearly 50 m (164 ft), with a surface layer of around 100 amphorae visible, representing various types, many originating from the Black Sea.
