LLANEUGRAD (LLAN-EIGRAD), a parish, in the hundred of TWRCELYN, union of ANGLESEY and county of ANGLESEY, NORTH WALES, 6 miles (E.) from Llanerchymedd; containing 331 inhabitants. This parish, which is bounded on the east by the Irish Sea, was anciently much more extensive than it is at present; and not far from the church, upon the site of a farm called Park, are distinct traces of a town or large village, of which the foundations of the buildings alone remain. In the year 873, a memorable battle was fought at BrS,ngoleu, within its limits, in which the Danes, who at that time made frequent descents on the coast of Anglesey, were defeated with great slaughter by Roderic the Great, who, after a sanguinary contest, obtained a signal victory over the invaders, and drove them to their ships. The soil of the parish is fertile, and the lands are inclosed and cultivated. The substratum is limestone, of which there are immense rocks; and extensive quarries of black and grey marble afford employment to a considerable number of the labouring poor; the situation of the place upon the coast affording a facility of exporting the produce, and great quantities being shipped to various parts of Great Britain. The living is a discharged rectory, with the perpetual curacy of Llanallgo annexed, rated in the king's books at £9. 11. 10k.; present net income, £135, with a glebe-house; patron, Bishop of Bangor. The church, dedicated to St. Eugrad, is supposed to have been originally built about the year 605, by Eugrad, son of Caw-o-Vrydain, and brother of St. Alltgo, who, about the same time, founded the neighbounng church of Llanallgo: it is a small but somewhat stately edifice, of lofty proportions, and venerable appearance; and adjoining it is a small antique chapel. On the farm of Llugwy, in the parish, formerly stood a chapel of ease to Llanallgo, the small existing remains of which are called Capel Llugwy. The poor are entitled to one-third of the rent of a farm in the parish of Llanvair-Mathavarneithfiv, arising from a bequest of John Williams, in 1721, and now let for £6. 12. per annum, which sum is annually distributed at Christmas; and there is also a small rent-charge of 5s., a grant of John Griffith Lewis, which is similarly appropriated. Adjoining the ancient town above noticed are the remains of an extensive and well fortified camp, in which Roderic is supposed to have stationed his forces in his conflict with the Danes; and on the highest eastern point are some remains, consisting principally of a gateway and some portions of ruined walls, of an old building, in which that sovereign is thought to have held his court while engaged in repelling the Danes from this part of his dominions.
