a walled seaport town of Naples, province of Terra di Bari, on the Adriatic, 16 miles W.N.W. of Bari. The town as approached from the sea has a fine appearance, many of the houses being handsomely built of a white stone resembling marble, but its streets are narrow and dirty. The principal buildings are,—a cathedral, several churches, a college, and a castle. The chief manufactures are linen goods and saltpetre. Some ship-building is also carried on. The harbour is formed by a mole and a sandbank, which acts as a breakwater, and is well sheltered, except from the N. wind. A considerable trade is carried on in corn, oil, almonds, and other articles. In the neighbourhood of the town there are some curious oval caves, arranged in tiers, and hewn out of a limestone rock. In all these saltpetre is found; and one of them, called the Nitre Cavern, is 1400 feet in circumference and 112 in depth. Pop. 17,000.
