Archaeologists in Sardinia said Thursday they have found the port of the Phoenician city of Tharros, held by some to be the ancient people's most important colony in the Mediterranean after Carthage.

Researchers from the University of Cagliari and Sassari found the submerged port in the Mistras Lagoon, several kilometres from the city ruins.

Excavations have long been going on at the site of the city itself, on a peninsula overlooking the Bay of Oristano in western Sardinia, but this is the first time its waterfront has been located despite almost two centuries of hunting.
