If you are in one the central harbours of Genoa, you are right in the middle of the town and close to everything you need. The city has ancient associations and was probably founded by Etruscans in the 8th-7th century BC. Greeks settled here in the 6th century, and it prospered until the Carthaginian War. The Romans rebuilt it and its present name possibly derives from this time when it was called Juana, the roman two-headed or god that traditionally guarded a roman gate or door. A good number of the castles and the forts around the Levant and down through Corsica and Sardinia are Genoese in origin or were at least occupied by the Genoese at some time. Genoa was at the forefront of the Renaissance and wealthy patrons attracted artist to the city, and architects designed some of the fine palazzos in the city. After the Renaissance it slowly declined, though it has always been an important city, and remains Italy's largest port.
