Kaleköy preserves the remains of the ancient Lycian city of Simena, dating back to the 4th century B.C. The city of Simena was submerged beneath the sea following devastating earthquakes, creating a fascinating sunken archaeological site. Swimming among the ancient sunken tombs and ruins offers an extraordinary experience, immersing you in the depths of history. Climbing to the Byzantine castle rewards you with breathtaking panoramic views of Kekova Bay, where you can witness the perfect combination of natural beauty and historical significance. The Roman-era theatre carved into the rocks and the impressive tomb monuments are absolutely worth exploring. Kaleköy provides a peaceful anchorage for sailors while offering an unforgettable journey through ancient Lycian civilization.
