This place is distinguished as the scene of a memorable battle that occurred between the army of OwaiTgrnndle: and the forces under the command of Sir Edward Mortimer, in which the latter was taken prisoner, with the loss of eleven hundred of his men. This battle, which is noticed by Shakspeare in his play of Henry IV., was fought on the 22nd of June, 1409 on a hilly common about half a mile to the north of the church, called Bqugliis. The parish is situated on the river Lug, and extends for about three miles in length, and a mile and a half in breadth; the greater portion of the land is inclosed, and in a tolerable state of cultivation; the surface is boldly undeleted; and the soil, especially in the lower grounds, is fertile and productive. The living is a perpetual curacy, annexed to Liangenllo, and endowed with £800 royal bounty; present net income, ao; patron, Bishop of St. David's ' - impropriator, Prebendary of Llangunllo in the Collegiate Church of Brecknock. The church, dedicated to St. Mary, is an ancient structure, consisting only of a nave and chancel, with a low tower, and not remarkable for any architectural details. The poor children of the parish are entitled to gratuitous instruction in the school erected and founded at Whitton, by Lady Child, of this place, who endowed it with £500, with which have been purchased lands now producing a rent of more than £100, and under the provisions of whose will a child of Pilleth is annually apprenticed, with a premium of £8. On a common in the northern part of the parish are a few scattered houses, forming a place called Hendre'r Genau. In the churchyard is a well, the water of which is said to be peculiarly efficacious in the cure of all diseases of the eye.
