The ancient theater of Aigeira is situated near the town of Aigeira at an altitude of 350m above sea level offering a view to the Corinthian gulf. 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 the Ancient Theater of Aigeira 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.
