Stratonikeia, a city in the interior of Caria, is located at Eskihisar Village, in the Yatağan district of the Muğla province. The first scientific excavations at the site began in 1977 under the direction of Prof. Dr. Yusuf Boysal. Prof. Dr. Bilal Söğüt has been carried out researches, excavations and restoration works since 2008.
Ancient writers Herodotus (v, 118), Strabo (xiv, ii, 25), Pausanias (5, 21, 10) and Stephanus of Byzantium (Ethnica 696) mention a settlement here named Chrysaoris or Idrias. After 281 B.C. the Seleucid King Antiochos I changed the name of the city to Stratonikeia after the name of his former stepmother and later wife. Stratonikeia and the surrounding region changed hands among the Seleucids, the Ptolemaics, the Macedonians, Rhodians and Romans. The city kept its importance in the Roman Imperial Period and developed continuously. It benefited greatly from the constructions carried out during the Early Imperial Period and especially the 2nd century A.D. In the Byzantine Era the see of Stratonikeia like other cities in the region was dependent on Aphrodisias.
