DUNGARVAN, a market town and seaport of Co. Waterford, Ireland, in the west parliamentary division, 281/2 m. W.S.W. from Waterford by the Waterford and Mallow branch of the Great Southern & Western railway. Pop. of urban district (1901) 4850. It is situated on the south coast, on the Bay of Dungarvan, at the mouth of the Colligan, which divides the town into two parts, connected by a bridge of a single arch. The eastern suburb is called Abbeyside, where the remains of an ancient keep, erected by the M’Graths, still exist, together with portions of an Augustinian friary, founded by the same family in the 14th century and incorporated with a Roman Catholic chapel. In the main portion of the town a part of the keep of a castle of King John remains. Brewing is carried on, and there are woollen mills. The exports consist chiefly of agricultural produce. Dungarvan was incorporated in the 15th century, was represented by two members in the Irish parliament until the Union, and returned a member to the Imperial parliament until 1885. It was fortified with walls by John when the castle was built. A story is told that Cromwell spared the town from bombardment owing to the wit of a woman who drank his health at the town-gate.
