Giving its name to the whole area, this long island stretches four miles before Kalekoy and is filled with historical ruins. At the southwestern end of the island is Tersane Bay where yachts may approach. On the southern side of. the bay is traces of sunken shops whose rooms are still discernible today. Leaving the jetty I one encounters by the apse of a Byzantine church. Though the place is full of ruins, no excavations have been carried out on this island, little is known about its history.
On the landward side of Kekova Island, j may see the ruins of a sunken city. Following shore, we see that half of the houses are submerged and that the stairways descend into the water. The foundations of buildings and houses can also be seen in the sea.
