Antiphellos Ancient Theatre

Perched on the hillside above Kaş, this Hellenistic theatre carved directly into the natural rock is one of the best-preserved ancient structures on Turkey's Aegean-Mediterranean coast. Dating back over 2,000 years, it seats around 4,000 and still follows the classic semicircular Greek design — tiers, orchestra pit, and all. What makes it special is the backdrop: you're looking straight out over the rooftops and into the deep blue sea while standing where audiences once watched performances. It's free to wander, uncrowded, and just a short walk from the town center.
