Phillip’s grave was in a place called Verginia, which I’m guessing is close to Pella.
Take me back to old Verginia....
The excavator who found the tomb claimed it was the tomb of Philip II, and many scholars agree with him, but others think it is more likely the tomb of Philip III Arrhidaeus (the mentally-defective half-brother of Alexander).
Amphipolis was originally an Athenian colony in Thrace, founded in 437 B.C. Thucydides the historian was exiled for not preventing the Spartans from capturing the city. That area was never Macedonian until the reign of Philip II so it doesn't seem like a likely place for a Macedonian king to be buried.
