Platamonas Castle
The function of a castle is to dominate an area and Platamonas must have done this brilliantly as it overlooks a huge stretch of the coast of Pieria. The high walls and well-preserved central tower date from the 10th century. While excavations have unearthed Hellenistic remains from the 4th century BC, it is the Byzantine churches and traces of the 10th-century town and its subsequent incarnations  that will grab your attention.
