Psathoúra

The volcanic island of Psathoúra (area 6 sq. km/2.25 sq. mi; alt. 65ft/20m) lies at the north-eastern tip of the chain of the Northern Sporades. There are remains of buildings belonging to an ancient city under the sea just off the coast of the island.

The light-house on rocky Psathoura is one of the most powerful of the Aegean Sea.
