To see the sights of the city the best to do is to take the bus to the centre and then making a walk up to the hill where is a Venetian Fortress from which you can have a complete view of the city. Then you can visit  the Roman Anphitheater, the Diana's Temple, the Sergie's Arch and other ancient ruins. Don't forget to watch ( starting at 10 p.m.) the world's famous illuminating giant cranes in the harbour's shipyard which change the colours every 3 min. making a fantastic rainbow in the night.
