Dokos island, in between Hydra and the Argolid coast, is a tiny, barren strip of land in the sea which was inhabited -according to sources- in the neolithic era (late 5th millennium BC) while during the early hellenic period (3rd millennium BC) it showed an increase in population mainly due to the advances in navigation.
The significance of the island, despite its small size, was huge and because of its geographical position controlled the area of sea around Laconia and the Gulf of Argolis. It was often used as a creek.
Today, there are few inhabitants, mostly fishermen. It is worth visiting for both its wild beauty and to admire the ancient shipwreck dating back to the second half of the 3rd millennium BC.
The Dokos lighthouse is located on the island. It was built in 1923 and stands at 9 meters tall.
