Dion Archaeological Park

The Archaeological Park of Dion (Dio) lies at the north-eastern foot of Mount Olympus in Pieria, Macedonia, Greece, about 5 km from the sea and 15 km from Katerini. In the Hellenistic period Dion was the religious centre of Macedonia, where Zeus was worshipped; Alexander the Great is said to have made sacrifices here before his campaign against Persia.

You can see several sanctuaries, including those of Zeus Olympios, of Zeus Hypsistos, known for its marble eagles, of Demeter with the oldest remains (6th century BC), and of Isis (2nd century AD), which is often flooded and reached by a small bridge. There are also large baths, a Hellenistic and a Roman theatre, and the remains of an early Christian bishop's basilica. The Dionysos mosaic was found in the Villa of Dionysos in 1987 and has been displayed since 2015 in its own building, the Archaeotheke.

The Archaeological Museum of Dion stands in the village, about 500 m west of the park, and opened in 1983. According to Lonely Planet it is known for its statues and mosaics; park admission includes the museum. A small visitor centre with a café is at the park.
