The ancient city Vergina that lies on the northern sloped of the mountains of Pieria can be safely identified as Agai which is the capital of ancient Macedonia. Archaeological evidence proves that the site was continuously inhabited from the Early Bronze Age (3^rd millennium BC) while in the Early Iron Age (11^th-8^th centuries BC) it became an important centre which was prosper and densely inhabited. The city reached its highest point of prosperity in the Archaic (7^th-6^th centuries BC) and Classical periods (5^th-4^th centuries when it was the most important urban centre of the area being the seat of the Macedonian kings and the place where all the traditional sanctuaries were established.

Moreover, it was already famous in ancient times for the wealth of the royal tombs which were built in their huge necropolis. The relics are protected by the archaeological museum of Thessaloniki where they are kept in a distinct area.
