A Copper Age (1300-1200 BC) cemetery was discovered just off of Agios Dimitrios, on the road to Elassona, on a wooded slope of Olympus (altitude 1100 m), at the “Spathes” site. The box-shaped graves brought to light vessels, swords and jewelry, with the characteristics of the Mycenaean civilization, which means either that the region was at some point inhabited by Mycenaeans or that its prehistoric inhabitants had trade relations with southern Greece. One of the swords is similar to the sword found in the Acropolis of Mycenae.
