a town of Naples, capital of the province of Basilicata, is situated in a deep valley on the right bank of the Gravina, a tributary of the Bradano, 128 miles E. by S. of Naples, and 44 E. from Potenza. The town, which is defended by walls, is generally well built; and contains a cathedral and archiepiscopal palace, which have porticos consisting of granite Corinthian columns, supposed to be the remains of an ancient temple. Not far from the walls stands an old tower known by the name of Torre Metella; and there are also in the town six convents and a college. The neighbouring country is rich in pastures; and the valley is surrounded by hills, which contain many curious caverns. Pop. 12,000.
