Kekova is a long island near the town of Kaş on the Lycian coast, about 200 km west of Antalya. The sheltered waters between the island and the mainland contain the partially submerged ruins of Dolişche, an ancient Lycian city whose coastal buildings sank after a series of earthquakes in the 2nd century CE. Staircases, building walls, storage jars, and cisterns are visible just below the surface in clear water, creating one of the most evocative underwater archaeological landscapes in the Mediterranean.
Glass-bottomed boats from Kaş and the village of Üçağız glide slowly over the ruins. Swimming and diving directly over the sunken city are prohibited to protect the site, but the view from the surface is clear enough. The surrounding area — Simena castle on its hill above the water, the tiny village of Üçağız with Lycian sarcophagi standing at the water's edge — is some of the most beautiful scenery on the Turkish coast.
