LLYSWEN (LLIS-WEN), a parish, in the union of HAY, hundred of TALGARTH, county of BRECKNOCK, SOUTH WALES, 7 miles (W. S. W.) from Hay, on the road to Builth; containing 172 inhabitants. This parish, of which the name implies a fair palace, was anciently one of the residences of the native princes of South Wales: the road from Hay to Buitth passes through it; and the annual value of the rateable property is returned at £370. The village is pleasantly situated oa the river Wye, which is not navigable here; the neighbourhood is well wooded, and the surrounding country abounds with rich and beautifully picturesque scenery. The living is a discharged rectory, rated in the king's books at £3. 14. 7.; and in the patronage of Mrs. Macnainara: the tithes hove been commuted for a rent-charge of £96. 4.; and there is a glebe of 37 acres, valued at £88 per annum. The church is a small edifice, close to. the bank of the Wye. There is a place of worship for Methodists. A day school, containing 25 children, is partly supported by Chas. Strettou, .Esq., of Llangoed Castle, and partly by payments from the parents; and a day and Sunday school, in which are about the same number, is partly supported by subscription; books are supplied by the rector. Llangoed Castle is situated within the parish; the mansion was erected in 1632, which date, inscribed on a stone over the ancient doorway, is still remaining. The grounds are very extensive, and comprehend some of the most beautiful and picturesque scenery in South Wales; and the surrounding eminences, of which some are very lofty, are clothed with stately and valuable timber to their summit. The river Wye, which here separates the counties of Breckoock and Radnor, skirts the demesne for nearly two miles and a half, and in its winding course is sometimes hurried with impetuosity over its rocky channel, and at others flows smoothly through its deeper bed, which in some places is more than forty feet in depth; the banks are richly planted with lofty trees, under which is a beautiful walk, extending through the grounds in a direction parallel with its course. The view from the church embraces a variety of beautiful scenery: to the south it extends over a fine tract of country towards the Hay, including the beautiful village of GlAsbury, and the Black Mountains; to the west are seen the luxuriantly wooded hills of Llangoed, ornamented with the finest forest trees, of every variety; and on the opposite bank of the Wye are the hills of Radnorshire, in the parishes of Bcughrood and Llanstephan. In the garden of an ornamental cottage near the church, is a tumulus, opposite to a remarkable horse-shoe bend of the river Wye.
