Bari (ancient Barium) is an industrial city in the Apulia region of southern Italy and a seaport on the Adriatic Sea.The old quarter of the city sits on a promontory separating the old and new harbours. It is the site of two notable Romanesque churches: the Basilica of San Nicola (11th-12th century) and the cathedral (late 12th century). Bari was formerly a Greek colony and later a Roman trading settlement. It came under the domination of the Lombards, the Byzantines, and the Normans. It was a key Italian naval base during World War II, and sustained heavy damage. From here you can visit Alberobello and Egnazia.
