Its construction dates back to 280-250 Β.C. Similar to the orchestra, the koilo is hewn on natural rock and when not available the soil was cut to accommodate stone seats. During the Hellenistic period it consisted of a two storey building. A corridor divides the koilo into two parts with a total capacity of 3000 spectators, its total length reaching 30,70 m.
