Bari (classic Barium), the chief town of the province, stands on a peninsula in the Adriatic about 135 miles N.E. of Naples, and possesses a tolerable harbour, being defended by old walls. The citadel dates from the 11th century, and there is a cathedral, the seat of an archbishopric, besides the old Norman church of S. Nicolas and other fine public buildings. Railways connect the place with Brindisi and Taranto. Within recent years the trade has greatly improved.
