The Zea Harbour Project combines land and marine archaeology to obtain a full picture of the ancient Zea Harbour in the Piraeus, Greece. The ancient naval installation at Zea is among the largest Classical building complexes, and it accommodated the ship of the line in the Classical period - the trireme. The objective of this website is to introduce you to the work of the Zea Harbour Project and its most important results. The Zea Harbour Project is a collaboration between the Ephorate of Underwater Antiquities, The 26th Ephorate of Prehistoric and Classical Antiquities and the Danish Institute at Athens.
