GWENDDWR (GWEN-DDWR), a parish, in the hundred of TALGARTH, county of BRECKNOCK, SOUTH WALES, 7 miles (S. by E.) from Builth, comprising the North and South divisions, each of which maintains its own poor, and containing 460 inhabitants, of which number, 234 are in the North, and 226 in the South, division. This parish, the name of which signifies "the fair water," is bounded on the east and north-east by the river Wye, which separates it from the county of Radnor, but is not navigable in this part of its course, and is traversed on that side by the turnpike road from Hay to Builth, which runs parallel and close to the river. The living is a perpetual curacy, in the archdeaconry of Brecknock, and diocese of St. David's, endowed with £800 royal bounty, and £700 parliamentary grant, and in the patronage of Arthur Macnamara, Esq., as impropriator of the small tithes: the rectorial tithes, which anciently belonged to the priory of D'or, were purchased from the crown, during the reign of Elizabeth, by Sir David Williams, under whose will they are now vested in trustees for certain charitable purposes. The church, dedicated to St. Dubricius, has a substantial steeple, but possesses no other claim to architectural notice. Some writers are of opinion that the celebrated seminary of that holy man was situated on the western bank of the Wye, in this parish. There is a place of worship for Baptists. The average annual expenditure for the support of the poor of the whole parish amounts to £375. 1., of which, £ 154. 14. is assessed on the North division, and £220. 7. on the South.
