The ancient theatre at Aigai is the modest, partially excavated remnant of the structure where Philip II of Macedon was assassinated in 336 BC, struck down by his bodyguard Pausanias during a wedding procession. The killing made his twenty-year-old son Alexander king of Macedon.
What survives is the lower part of the cavea cut into the natural slope and the foundations of the stage building. There is little to see in terms of standing masonry, but the location — directly below the palace, with the plain of Imathia opening out below — gives a vivid sense of the political theatre of the Macedonian court. Free to enter as part of the archaeological park.
