Among the first archaeological sites discovered in Mount Olympus was the excavation site Spathes . It is a necropolis from the Late Bronze Age. The oldest tombs are from the 14th century BC, the last traces of the use were found from the end of the 13th century, the beginning of the 12th century BC. The settlement, associated with the necropolis, has not been found. Many of the burial offerings were made in the Mycenaean style, so that the Mycenaean cultural circle probably also extended over the border of Thessaly to Pieria.
