LLANYMYNECH, a parish in the hundred of OSWESTRY, county of SALOP, 6 miles (S. by W.) from Oswestry, containing, with the townships of Llwyntlanan and Treprenal, 454 inhabitants. The living is a rectory, in the archdeaconry and diocese of Llandaff, rated in the king's books at £ 12. 13. 4., and in the patronage of the Bishop of St. Asaph. The church is dedicated to St. Agatha. Limestone of the finest quality abounds in the parish, and there are kilns for burning it. Copper and lead ore are also found in the neighbourhood, but though no mines are now in operation, the " Ogof," a Welch word for cave, is evidently the mouth of an ancient mine, near which are vestiges of a Roman encampment. The Llanymynech canal passes through the parish.
