Gökova is a municipality (belde) in the district of Ula in Muğla Province, Turkey. It lies at the head of the Gulf of Gökova in a plain also known as Gökova. The ancient Carian city of Idyma, with its acropolis and necropolis, is located above Kozlukuyu Mahallesi (Kozlukuyu Neighbourhood) at the northern end of Gökova town, not at nearby Akyaka as often incorrectly stated.
The name Gökova means "blue" (gök) "plain" (ova) and refers to the plain on which the town of Gökova is situated. Today in the plain of Gökova there are two towns called Gökova and Akyaka, six villages named Ataköy, Akçapinar, Gökçe, Çitlik, Şirinköy and Yeşilova. The population is about 10,000.
Gökova town is situated about 2 km inland from the holiday resort of Akyaka. Gökova town is a separate municipality from Akyaka, yet Idyma's acropolis and necropolis are often erroneously attributed to Akyaka. However, there is relatively little of archaeological interest in Akyaka. Gökova town's Kozlukuyu Mahallesi is a first degree archaeological area with the ruins and rock cut chamber tombs of Idyma dating to 5th Century BC.
The first recorded mention of Idyma (now Gökova) was in 546 BC. as a member of the Attika-Delos Sea Union founded against the Persians with the leadership of Athens. Idyma became a member of the Union by paying 1 Talent and 890 Drachmas in taxes. Idyma minted its own silver coins in the second half of the 5thC BC. The coins show the name IDIMION and the head of the God Pan on the reverse side.
Gökova was, until 1999, a village governed by a mukhtar. In 1999 it became a township or municipality with an elected mayor by a decision made by the Council of Ministers in November 1998. In the first local elections in April 1999, Mayor Durmus Ali Sazakli was elected. The Belediye [town council] has four civil servants and a small staff which may be expanded in the future. The township covers an area of 1,900,000 sq. metres.
As the area of Kozlukuyu, lying directly at the foot of the Idyma necropolis, is now a first degree archaeological area, new building permission is naturally refused. There is no direct route to either the acropolis or necropolis, both of which can only be reached by climbing.
