LLANVIHANGEL-HELYGEN (LLANFIHANGEL-HELYGEN), a parish, in the union and hundred of RHAIADR, county of RADNOR, SOUTH WALES, 5 miles (E.) from Pen-y-Bont; containing 102 inhabitants. This parish, comprising by computation 845 acres of inclosed, and 300 of common land, is situated on the river Ithon, along the banks of which, and those of the river Dulas, it extends for about five miles, and is nearly of equal breadth: the high road leading from Rhaiadr to New Radnor, Knighton, and Presteign, and to Kington and Leominster, in Herefordshire, passes within two miles of the church. The surface is hilly, and the soil various, consisting principally of clay in the lower grounds, and being light and shallow on the hills; the surrounding scenery is pleasingly varied, and from the higher grounds some good views are obtained over the adjacent country. The living is a perpetual curacy, endowed with £800 royal bounty, and with half of the tithes of the parish; net income, £80; patron, Vicar of Nantmel. The church, dedicated to St. Michael, is a small edifice, consisting of a nave and chancel, and is not distinguished by any architectural details. A Sunday school is maintained by subscription, for gratuitous instruction; and a small day school in the village is partly supported by the same means; the schools together contain 30 children. In the parish are the remains of a Roman station on the banks of the Ithon, upon a farm called Cwm, which are described under the general head of Radnorshire.
