"17 miles beyond Kalkan the coastal highway brings one to Kas. this is the southernmost town on the Lycian coast of Turkey. Kas has been identified as the site of Antiphellus, an ancient Lycian town whose archaeological record dates back the sixth century C.E. The principal surviving monument of Antiphellus is this Hellenistic theater."
