Kekova
Kekova (Greek: Dolichiste), is a thin and long island with a length of 7.4 km. and a width of approximately 500 m. which faces the villages of Uçağız (Teimiusa) and Kale (Simena) near Demre district of Antalya province. It is often referred to as "Kakava" in sources. Kekova has an area of 4.5 km2 and is uninhabited. The island, which has hostels and cafes, is accessible by boat. The depth of the sea, which looks like a channel between the mainland is 105 m. and whose highest peak is 188 m. On its northern side, there are the partly sunken ruins of Dolikisthe, an ancient town that was destroyed by an earthquake during the 2nd century. Rebuilt and still flourishing during the Byzantine Empire period, it was finally abandoned because of Arab incursions. After the Italian occupation of Kastellorizo, Kekova was disputed between Italy and Turkey. The 1932 Convention between Italy and Turkey assigned it to Turkey. The Kekova region was declared a specially protected area on 18 January 1990 by the Turkish Ministry of Environment and Forest. All kinds of diving and swimming were prohibited and subject to special permits from governmental offices. In later years the prohibition has been lifted except for the part where the sunken city is.
The name Kekova has been used frequently in the fields of tourism and conservation due to because of its up-to-dateness in recent years. Boat tours from Çayağzı (Andriake) have begun to be known as "Kekova tour", and more importantly, the archaeological and natural protected areas around the island and its surroundings are named as "Kekova Site Area".
Kekova, which has the cleanest sea not only of Antalya but also of the whole Mediterranean world, owes this cleanliness to undisputed protection. Having gained immense appreciation from foreign visitors this issue has been a source of pride in the international protectionism Republic of Turkey. The island has never had the characteristics of the city like the two small harbors opposite it. It mostly protected the two cities against the Mediterranean like a curtain; It was used as a seafarers' shelter, shipbuilding and repair base. In this area, the ruins on the northwest coast of the island, which is called "Sunken City" today, are at least BC. It is the most colorful corner of Kekova, which has been used as a commercial and military base since the 5th century. Tersane Bay is both a place to swim and the area with the highest concentration of archaeological remains with its main apse from the Byzantine Period. In the corner known as the sunken city nearby, there are settlements carved into the mainland and foundations in the water. The fact that the structures in this corner were submerged can only be explained by the fact that they lie towards the mainland from this corner of the island, probably as a result of the earthquake.
