Piraeus has been the Athenian port since ancient times. It is made up of various ports which expand in the natural inlets of the Aktì peninsula, situated at about 10km south west of the city centre. The three inlets which house its ports are Kantharos, the biggest that is used as a commercial port, Zea, the middle sized one, used as a yacht marina, Microlimano the smallest and most typical of Piraeus, used mainly by fishing boats and is dotted with cafés and fish restaurants.
Piraeus is densely inhabited. It has about 175,000 inhabitants and as in most quarters of Athens, there is a vital autonomous commercial centre, a great night life around the areas of Zea and Microlimano, an important archaeological museum and some sports facilities which will be used during the 2004 Olympics.
