LLANVAGDALEN, or LLANVAGLAN (LLAN-FAGLAN), a parish, in the hundred of ISGORVAI, union of CARNARVON and county of CARNARVON, NORTH WALES, 2 miles (W. S. W.) from Carnarvon; containing 205 inhabitants. This parish, which derives its name from the dedication of its church to St. Baglan, is situated on the Menai strait, near its southern extremity, and is bounded on the north and east by Llanbeblig, on the south by Llanwnda, and on the west by the strait; it comprises between 600 and 700 acres, of which about one-half is amble. The soil and surface of the land are various; in some parts the high, rugged, and sterile rocks strikingly contrast with low and fertile grounds of hazel loam, producing good crops of wheat, barley, and oats; and the scenery is enriched by some fine plantations of oak, ash, and alder trees. The parish, of which the rateable annual value is returned at £512. 8. 5., comprises only a few farms and widely-scattered dwellings. The living is a perpetual curacy, annexed to the vicarage of Llanwnda: the tithes have been commuted for a rent-charge of £123, of which £115 is the amount payable to the Principal and Fellows of Jesus' College, Oxford, and £8 to the vicar, who has also a glebe of six acres, valued at £1. 5. per annum. The church, situated in the centre of a large field, to which there is no public road, is an ancient edifice, consisting of a nave and chancel, with a spacious chapel on the north side: the eastern gable is ornamented with the remains of an old cross, curiously sculptured.
