FAGAN'S-ST, a parish, in the hundred of DINASPOWYS, county of GLAMORGAN, SOUTH WALES, 4 miles (w. N. w.) from Cardiff, containing 446 inhabitants. This parish takes its name from the saint to whom its church is dedicated, and who, according to all testimony on this subject, arrived in Britain about the year 180, to preach the doctrines of the Christian religion, and founded the church of this place, which may be consequently regarded as one of the earliest Christian establishments in the island. St. Fagan's is celebrated as the scene of a sanguinary battle, which took place during the protectorate of Cromwell, between the recreant leaders of the parliamentary forces in the principality, and Colonel Horton, who was sent by the protector, with a small army, to enforce the order for disbanding them. The former, among whom were Major-Generals Stradling and Laugharne, having embraced the cause of royalty, contrived to keep their forces under arms, and to augment their number by fresh recruits of such as were favourable to the cause of royalty; and having increased their army to eight thousand men, they confidently advanced to meet Colonel Horton, who had stationed his forces at St. Fagan's. The battle was fought on the 8th of May, 1648, and terminated in the defeat of the Welsh troops with great slaughter, and the capture of many of their principal officers. Among the slain, on the part of the Welsh, were sixty-five of this parish alone; and in the ensuing harvest, so great was the scarcity of labourers, that the crops were chiefly cut and gathered by women. This victory was considered by the parliament to be of such importance, that a day of public thanksgiving was appointed on the occasion. The village, which is situated on the river Ely, a stream abounding with trout and other fish, has a very prepossessing appearance; it lies on a substratum of limestone, and is abundantly supplied with excellent water: plenty of coal is found within five miles of the place, and is supplied at a moderate price to the lime-works in the parish. The living is a rectory, with Llanilterne annexed, in the archdeaconry and diocese of Llandaf, rated in the king's books at 1614. 9. 7., and in the patronage of the Earl of Plymouth. The church is a very neat edifice, in excellent repair. The Rev. John Cooke, in 1729, gave 450, producing £ 2. 10. per annum, and secured on the Cardiff turnpike trust, for the instruction of three children of this parish, and two of the chapelry of Llanilterne; and there are some small charitable bequests for distribution among the poor. Here is an ancient castellated mansion, formerly belonging to the family of Lewis, the heiress of which has conveyed it by marriage, together with a large estate in this county, to the Earl of Plymouth: it is still habitable, and is now in the occupation of a tenant under the present proprietor. The average annual expenditure for the maintenance of the poor amounts to £327. 13.
