The Aigai theatre
The theatre where Philip II was murdered was founded in the mid-4th century BC, on the large terrace where the Palace was built, and in organic unit with it.
Moreover, the two buildings are the most ancient testimony of royal regime (basileia) that would prevail all over the ancient world during the Hellenistic and Roman times. The theatre has one earthen aisle (diazoma), while only the first row seats and the stage (skene) were made of stone. The orchestra, in the centre of which the stone foundation of the thymele, the altar of Dionysus, remains intact, has a diameter of 28.40m.
