Dion

Dion or Dio is a village and a former municipality in the Pieria regional unit, Greece. Since the 2011 local government reform, it is part of the municipality Dio-Olympos, of which it is a municipal unit. It is best known for its archaeological site and Archaeological Museum. Zeus was honored at the ancient city of Dion located at the foot of Mount Olympus. It is located 15 km. SW of Katerini, 425 km to the north of Athens and 65 km to the north of Larissa.

The village owes its name to the important sanctuary dedicated to Zeus (Dias, "of Zeus"), leader of the gods who dwelt on Mount Olympus; as recorded by Hesiod's Catalogue of Women, Thyia, daughter of Deucalion, bore Zeus two sons, Magnes and Makednos, eponym of Macedonians, who dwelt here in Pieria at the foot of Mount Olympus. The ruins of the ancient city lie within the modern city's boundaries.
