a town of Bosnia, capital of the province of Herzegovina, is situated on both sides of the Narenta, 72 miles N.W. of Cattaro. It is surrounded by embattled walls, which inclose a much larger space of ground than is actually occupied by buildings. The streets are for the most part unpaved; and the town contains several mosques and churches, and two large bazaars. The name Mostar, which signifies "old bridge," is derived from the Roman bridge of a single arch which crosses the river. Swords and fire-arms are manufactured here; and there is an active trade in corn, wine, fruits, cattle, tallow, and wax. Pop. 7300.
