In the 6C B.C. a first stage was built in the sacred enclosure dedicated to Dionysos, where the famous Dionysian festivals were held. These installations gave way at the start of the next century to a genuine theatre where you missed the great plays of classical theatre! Modified by the Romans and abandoned after the barbarian invasions, restoration dates from the end of the 19C. When visiting it, remember you are in the theatre of the most complex of the Olympian gods.
