After passing Serik on the Antalya-Alanya highway, you turn north and continue for 4 km. It dates back to the 5th century B.C. The theater which was built in the 2nd century A.D. was periodically repaired by the Seljuks who used it as a caravansaray. It is one of the best preserved theaters to be found today. Allowing 0.50 m. per seat, the theater holds 7000 spectators, with an additional 500 in the orchestra. Today it is used for concerts, festivals and grease wrestling events. In addition to the theater the agora, basilica, nymphaeum and 15 km. of aqueducts are to be seen.

About 35 km. along the Antalya-Alanya highway, you turn north and continue 8 km. until Silyon is reached. It was built on an ellipse-shaped table-like plateau rising above the flat plain. Due to its location the surrounding areas can easily be seen, and in fact the view stretches as far as the Mediterranean. It was settled in the 4th century B.C. and it lived not only through the Hellenistic, Roman and Byzantine periods, but was also used by the Seljuks who also added buildings and increased its wealth. Some of its interesting sights are the stadium, gymnasium, turrets, Seljuk mosque, the theater whose proscenium is buried under rocks, and the sports arena.
