The Philippeion (Greek: Φιλιππεῖον) in the Altis of Olympia was an Ionic circular memorial in limestone and marble, a tholos, which contained chryselephantine (ivory and gold) statues of Philip's family: himself, Alexander the Great, Olympias, Amyntas III and Eurydice I.
It was made by the Athenian sculptor Leochares in celebration of Philip's victory at the battle of Chaeronea (338 BC).
Inside it had nine engaged columns of the lavishly designed Corinthian order.
It had a carved marble roof which was decorated with a bronze poppy head on top.
