There are some Macedonian tombs and the necropolises of Pydna around ancient Pydna and beside the ancient road from Methone in the north to Dion in the south. The oldest tombs are from the Bronze Age; the youngest are from the early Christian period. Smaller tumuli have eroded over time and are no longer visible. Most excavations have had to be carried out to save the sites. The finds in both areas show a shrinking population during the second Greek colonization.
