A city in the periphery of Attica, Greece, Piraeus was the port of the ancient city of Athens. It still remains to be among the busiest shipping and industrial centers of the Mediterranean.

The city was inhabited since 2,600 BC and its name means “the place over the passage.” Piraeus is also a commercial hub of Greek shipping. Its estimated population is 175,700 as of 2001. Piraeus is made up of rocky promontory that contains three natural harbours. The bigger one is located on the north-west and is an important commercial harbour for the eastern Mediterranean Sea and the other two smaller ones which are named Zea and Mikrolimano are used for naval purposes.
The port provides ferry routes to almost every island situated in the eastern portion of the country, the Cyclades, island of Crete, Dodecanese, and the northern and eastern Aegean. The western part of Piraeus is used in cargo services and much of this part of the harbour is within suburban Drapetsona and Keratsini.
