Founded in the 9th century BC, Kaunos (or Caunus) was an important Carian city by 400 BC. Right on the border with Lycia, its culture reflected aspects of both empires.
The theatre is very well preserved. On the hill above there are remnants of an acropolis and fabulous views over the surrounding countryside. On the same level as the theatre there are impressive ruins of a Roman bath while down the slope is the port agora .
