Porto Torres (locally Poltu Torra in Sassarese), is a town in northern Sardinia (province of Sassari), of about 20,000 inhabitants.
It has an archeological area, with ruins of Roman baths. The 11th-century, three-naved Cathedral of San Gavino, which was built using only precious hardstones like marble, porphyry and granite, is the largest Romanesque church in Sardinia.
Instead of the usual western facade and eastern apse, the Cathedral sports two apses. The crypt holds several Roman sarcophagi.
Chemical industries support the modern economy of Porto Torres.To get to the port from the town center, just follow the signs for "Porto Industriale".
