It is situated among the hills on the river Avon Llwyd, near the Brecon and Monmouthshire canal, and at the base of the bold elevation of Mynydd-Maen. It is supposed to have arisen out of the ancient village of Trevethan, and is now a busy manufacturing place.
The town, which is large, but irregularly laid out, is a polling-place for the county elections, and a petty sessions town. In the reign of Charles II., Thomas Allgood introduced the manufacture of japanned wares, in imitation of those brought from Japan, and his son invented a new process of polishing iron, called, from its having been first practised here, "Pont-y-Pool ware"; but these manufactures have since been transferred to Birmingham. The prosperity of the town was further secured by the Hanburys, who first made tinned and sheet iron here in the 17th century.
The town of late years has greatly increased in importance, and now contains many well-built houses and shops. The principal public buildings are the townhall, an Italian structure recently presented to the inhabitants by C. Hanbury Leigh, Esq., of Pontypool Park; a theological college, savings-bank, two commercial branch banks, a brewery, gas works, iron mills for making tin plates, and several extensive forges. Many of the inhabitants are employed in the neighbouring collieries, iron mines, and lime works with which this district abounds. There are tram-roads leading from the works in various directions.
In the vicinity are the hamlets of Pont-y-Moyle, Trostnant, Trefeddyn, and Varteage, at which last are situated the furnaces of the British Mining Company. The living is a perpetual curacy in the diocese of Llandaff, value £85, in the patronage of the Vicar of Llanover. The church, dedicated to St. James, is a very ancient stone structure with a small chapel of the Hanburys. There are places of worship belonging to the Roman Catholics, Baptists, Wesleyans, Independents, and Society of Friends, also National and other schools.
The principal residence is Pont-y-Pool Park, situated on rising ground on the right of the town, from which it is divided by the river Avon Llwyd. The views from its grounds are varied and extensive. The mansion contains paintings by Murillo and other eminent masters. The Pontypool Poor-law Union comprises 22 parishes or townships It is also the head of new County Court and superintendent registry districts. A court-leet is held annually for the lords of the manors of Wensland and Brynwyn, at which the stewards preside. Market day is Saturday. Fairs are held on the 2nd April, 22nd April, 5th July, and 10th October, for the sale of horses, cattle, and cheese."
