ABERGAVENNY, a market-town and parish, partly in the upper, but chiefly in the lower, division of the hundred of ABERGAVENNY, county of MONMOUTH, 16 miles (W. by N.) from Monmouth, and 145 (W. by N.) from London, on the road to Milford-Haven, containing, with the hamlets of Hardwicke and Lloyndu, 3592 inhabitants. This was the Gobannium of Antoninus, a Roman station so called from the river Gobannius, now the Gavenny, from which the present name of the town is formed, by prefixing the word Aber, denoting its situation near the mouth of that river. Soon after the Conquest, a castle was erected here by Hameline de Balun, or Baladun, one of William's followers, who also founded a priory for Benedictine monks, in honour of the Blessed Virgin, the revenue of which at the dissolution was £59. 4.; it stood in Monk-street, the site being now occupied by a modern dwelling, called the Priory House. Of the castle, the only remains are the exterior walls, which appear to have been erected in the time of Henry II., after it had been destroyed by the Welch: within these a neat modern structure has been erected for a residence. The town is beautifully situated at the extremity of a pass where the mountains abruptly terminate, and is watered by the rivers Usk, Gavenny, and Kibby, over the first of which is a beautiful ancient bridge of fifteen arches: it is lighted with gas, and well supplied with water, conveyed into the houses by pipes from springs in the vicinity. The streets are narrow, and the houses irregularly built; but considerable improvements have been made by the enlargement of the market-place, and the removal of numerous projections in front of the buildings. The salubrity of the air and the picturesque scenery attract numerous visitors during the summer months. Assemblies are occasionally held in the winter, chiefly for the promotion of charitable purposes. The trade is principally in wool, a considerable quantity being sold on the market days during the months of June and July. The mountains in the neighbourhood abound with coal and iron-stone, and in the surrounding districts numerous iron-works have been established, which are rapidly increasing. The Monmouthshire and Brecon canal, passing within half a mile of the town, affords great facility in distributing the produce of the mines to every part of the kingdom, and to the south of France. The market days are Tuesday and Saturday, the latter principally for corn: during the months of June and July a great quantity of wool is brought to the market. The fairs are held on the third Tuesday in March, May 14th (which is the principal), June 24th, the Tuesday before July 20th, September 25th, arid November 19th. The charter of incorporation, by which the government of the town was vested in a bailiff, recorder, and twenty-seven burgesses, having become forfeited in the reign of William III., the town is within the jurisdiction of the county magistrates, who hold a petty session every Tuesday. A court for the recovery of debts under 40s, is held under the lord of the manor, the authority of which extends over a district ten miles in circuit. The general quarter sessions of the county were formerly held here, but they have been removed to Usk. The living is a discharged vicarage, in the archdeaconry and diocese of Llandaff, rated in the king's books at £10. 0. 7, endowed with £600 royal bounty, and in the patronage of Charles Kemeys Tynte, Esq. The church, dedicated to St. Mary, is a spacious structure in the Norman style of architecture, and contains several very ancient monuments, principally of the Herberts. There are two places of worship each for Baptists and Independents, and one each for Wesleyan Methodists and Roman Catholics. The free grammar school, founded by Henry VIII., in 1543, and formerly under the management of the corporation, was, on the forfeiture of their charter, placed under the control of the Master and Fellows of Jesus' College, Oxford, who appoint the master, whose salary is £40 per annum, giving preference to a fellow of that college. The number of scholars on the foundation is eighteen: the school-house was formerly the parochial church of St. John, which was converted to this purpose at the dissolution. About the middle of the last century it was rebuilt, but still, from its embattled tower, it presents the appearance of an ecclesiastical structure. William Prichard, in 1623, founded a scholarship in Jesus' College, Oxford, to which boys educated at this school are eligible. There are also a Lancasterian and several Sunday schools. A variety of Roman coins, among which was a gold Otho, some bricks inscribed "Leg. II. Aug.," and a sudatory, have been discovered in the town; and within half a mile of it are the remains of a Roman camp, near which was a chapel of ease, now converted into a farm-house. At Lloyndu is a mineral spring, said to have been efficacious in the cure of scrofula. Abergavenny confers the title of earl on the family of Neville; the earldom, like that of Arundel, is a local dignity, attached to the possession of the castle, and the only one, now subsisting, of those baronies with which the Norman warriors, who assisted in the subjugation of Wales, were rewarded.
