LLANLLIGAN, or LLANLLUGAN (LLAN-LLUGAN), a parish, in the union of NEWTOWN-AND-LLANIDLOES, lower division of the hundred of NEWTOWN, county of MONTGOMERY, NORTH WALES, 4 miles (S. W.) from Llanvair; containing 413 inhabitants. This place is distinguished as the site of an ancient Cistercian nunnery, which, according to Tanner, was founded prior to the year 1239, when the tithes of the parish of LlanvairCaereinion were given by Bishop Hugh to the "nuns of Llanllugan in Powys," to whom also the tithes of Llanllwchaiarn and Bettws were subsequently appropriated by Anian, Bishop of St. Asaph, in 1265. This establishment, of which the founder is not known, had, at the dissolution, a revenue estimated at £22. 13.8.: the site was granted, in the 37th of Henry VIII., to Sir Arthur D'Arcy, Knt.: the only remains are some fragments of painted glass in the chancel window of the church. The parish, situated nearly in the centre of the county, is intersected by the small river Rhiw, which has its source in the immediate vicinity, and, after passing by the village, pursues its course in an easterly direction, and falls into the Severn at Berriew. It is about three miles in length and a mile and a half in breadth, and a very large proportion of it is uninclosed and uncultivated; its rateable annual value is returned at £1344. The surrounding scenery is agreeably diversified, and in some parts highly picturesque; and the views over the adjacent country embrace many interesting features. The road from Welshpool and Llanvair passes through the parish by Cevn Coch to meet that from Newtown and Machynlleth, at Talerddig, in the parish of Llanbrynmair. The living is a perpetual curacy, endowed with £1000 royal bounty, and in the patronage of the Lord of the Manor, and other impropriators, who are owners of land; net income, £49. The church, dedicated to St. Mary, and situated on the bank of the river Rhiw, is an ancient structure, in the early style of English architecture. There is a Sunday school, in which 130 males and females are taught gratuitously by Calvinistic Methodists. About a mile to the south-west of Cevn Clich, and to the right of the road from Newtown and Machynlleth, are the remains of a Druidical circle.
