Dion was an ancient town strategically located and one of the most famous Macedonian states.
Its geographical location is placed at the foot of mount Olympus, where there is a town with the same name in our days.
As both Stravon and Livius report, Dion “was a town not in the Thermaikos Gulf, but was located at a distance of seven stadium, below Olympus.”
The first written report for Dion was by Thucydides, who mentions it as the first town that general Vrasidas marched from in 424 B.C.
