Porto Torres: Turris Libisonis National Museum
and 2,000 Years of Roman History in Northern Sardinia

“Porto Torres is our city. We see it every day as a ferry port. But beneath our feet lies one of Sardinia’s largest Roman settlements — complete with thermal baths, a forum and mosaics. And very few people know about it.”

Turris Libisonis was the main Roman colony in northern Sardinia — a Roman trading port that was active from the 1st century BC. The thermal baths, the forum and the Roman bridge: they are all there, beneath Porto Torres. The modern town has grown up over the ancient one.

🏛️ Turris Libisonis — The Roman City

Porto Torres originated as Turris Libisonis, a Roman colony founded in the 1st century BC — the main commercial port of northern Sardinia. It exported grain, timber and minerals to Rome. The city had thermal baths, a forum, temples and a well-equipped harbour. Parts of all this are still visible — and the National Museum brings this history to life with a collection of exceptional importance.

❓ FAQ — Porto Torres Romana

What was Turris Libisonis?
Turris Libisonis was the main Roman colony in northern Sardinia, founded in the 1st century BC and active for around 600 years. It was an important trading port that exported wheat, timber, metals and Sardinian agricultural produce to Rome. The city possessed the characteristic features of Romanisation — a forum, thermal baths, an aqueduct and a well-equipped harbour. The remains of this city lie beneath and around the present-day Porto Torres, and the National Museum houses its most significant artefacts.

Is the Basilica of San Gavino worth a visit?
Absolutely — the Basilica of San Gavino is the largest Romanesque basilica in Sardinia and one of the island’s most important medieval monuments. Built between 1065 and 1111 by the Doria family of Pisa, it features a two-tone façade and a three-nave interior of great Romanesque simplicity. Inside are the tombs of the Torres martyrs from the 3rd century. It is open to the public and admission is free.
