Its busy port is a leading commercial and industrial centre as well as a transit point for travellers catching ferries across the Adriatic to Greece. Bari comprises a new and an old town. To the north, on a promontory between the old and new harbours, lies the picturesque old town, or Citta Vecchia, with a maze of narrow, crooked streets. To the south is the spacious and regularly planned new town, which has developed considerably since 1930, when the Levant Fair was first held here. The heart of the modern town is Piazza della Liberta. The busy thoroughfare, Corso Vittorio Emanuele II, separates the new town from the old. At the eastern end of the Corso begins the Lungomare Nazario Sauro, a magnificent seafront promenade that runs along the old harbour. Bari and the Apulian region were long recognized for their strategic location, attracting a succession of colonizers such as the Normans, Moors and Spaniards, each leaving their mark.
