Dion has a population of 1554 inhabitants and is an important point of interest for Greek and foreign tourists alike. Each year thousands of tourists visit the archaeological site and the Archaeological Museum to admire the findings from the holy city of the Macedonians. In the summer the Ancient Theatre is brought to life with performances and concerts of the Olympus Festival.
Dion was the holy city of the Macedonians. Its heyday is dated to the years of Archelaus (414-399 BC) when the king would organise nine days of games in honour of Olympian Zeus and the Muses. Furthermore it was here that Philip initially celebrated his glorious victories and Alexander the Great began his great campaign in the name of Olympian Zeus.
