Porto Torres (, ) is a comune and a city of the Province of Sassari in north-west of Sardinia, Italy. Founded during the 1st century BC as Colonia Iulia Turris Libisonis, it was the first Roman colony of the entire island. It is situated on the coast at about east of Capo del Falcone and in the center of the Gulf of Asinara. The port of Porto Torres is the second biggest seaport of the island, followed by the port of Olbia. The town is very close to the main city of Sassari, where the local university takes office. Toponymy Historically the settlement was founded with the Latin name "Colonia Iulia Turris Libisonis", composed with Colonia (name of the Roman settlements) Iulia (name of the Julia gens) Turris (litt. "tower", referred probably to a nuraghe built not so far from the town or to the Monte d'Accoddi) and Libisonis (referred to Libya, probably because in the same are there was a Phoenician trading outpost. "Libya" is the ancient name of the entire northern coast of Africa). After the fall of the Western Roman Empire the town was known simply as "Turris". During the Middle Ages during the Judicate of Logudoro the name was corrupted with "Torres" and after, during the Aragonese period, the town was known simply with the Catalan name of "Lo Port" (The port). During the Savoy reign it was known with the name of Portotorre (Porto+Torre; "Towerport"). Until the 1960s the town was commonly known as "Portotorres", and only after the official recognition of the status of city the name has officially changed in Porto Torres. History Prehistorian and Nuragic period The Miocene In the frazione of Fiume Santo in 1994 has been find a lot of animal fossils presumably dated at the Miocene. Some 8/9 millions years old rests of Oreopithecus bambolii has been find in the same area. The discovering has started casually thanks to some hobbyist paleontologists that have noticed after some maintenance works in the near thermal power station the presence of some fossils in the excavation debris. In the area has been individuated 15 vertebrate species like giraffes, crocodiles, turtles, suidae and Mustelidae. Most of these animals like the Umbrotherium azzarolii were herbivorous, but some others like the Indarctos anthracitis were omnivores. Prehistory Ancient human presence in the municipal territory of Porto Torres is certified thanks to many necropolis in the area.
