The port of AntirrioEdit

The Port of Antirrio is an important ferry port for traffic from the Peloponnese to northwestern Greece. Before the construction of the bridge it played a very important role in the transportation of people and goods between mainland Greece and Peloponnese. Its significance has decreased since the opening of the Rio-Antirrio bridge in 2004. Adjacent to the port there is a lighthouse and the fortress of Antirrio.

On the eastern pier of Antirrio port there is the Antirrio RTS (Regional Traffic Service)[5] which is part of the national Vessel traffic service system of Greece (Officially called Vessel Traffic Management and Information System). The RTS of Antirrio includes a building with the necessary electronics/communication equipment and a sensors/radar mast of 20m height. On top of the mast there is a remotely controlled CCTV camera, VHF antennas and the antenna of the coastal surveillance and navigation radar GEM RT02-25D.[6]
