Thermaic Gulf

The Thermaic Gulf forms the northwestern corner of the Aegean, with Thessaloniki at its head and the rivers Axios and Aliakmon among those flowing into it. Founded by Cassander of Macedon, Thessaloniki grew into a major port and Byzantine metropolis. The Ottomans conquered it in 1430, and it remained an important seaport under their rule. To the west stood Pella, the ancient capital of Macedon, once closer to the gulf before river sediment extended the shore.
