The ancient theater of Aigeira is situated near the town of Aigeira offering a view to the Corinthian gulf. Its construction dates back to 280-250 BCE. 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 3.000 spectators, its total length reaching 30,70 m. Work on the monument began in August 2011 and the operation was completed in December 2015.The restoration of the ancient theater of Aigeira as a sub-project of the larger project “Restoration and promotion of the archaeological site of Paleokastro Aigon (Ancient Aigeira)” has been included in the NSRF.
