there are two major sea ports in Italy one being Genoa.
it is Port of Portland!
The major seaport by volume of goods would be Sydney (Port Botany), however there are large number of ports, some which are mainly geared for exports such as coal, bauxite and iron ore.
A port is a place were boats are parked :D
um... well... Port-au-prince is a city. the capital of Haiti actually.
