Telmessos Ancient Theatre

Right in the heart of Fethiye, the Telmessos Theatre is a Roman-era gem dating back to the 2nd century AD, with a cavea stretching 78 meters wide and 28 rows of seats still largely intact. It's one of those places where the ancient world feels surprisingly close — you're essentially sitting where crowds gathered two millennia ago. Worth noting: restoration work here has been controversial, with some locals arguing the use of modern Afyon marble has compromised its authenticity, so you'll see the tension between preservation and intervention up close.
