LLANVAIR-PWLLGWYNGYLL (LLANFAIR-PWLL-GWYNGYLL), a parish, in the union of BANGOR-AND-BEAUMARIS, hundred of TYNDAETHWY, county of ANGLESEY, NORTH WALES, 2 miles (W. by S.) from Bangor; containing 617_inhabitants. The name of this parish is,derived from the dedication of its church to St. Mary, and its. distinguishing adjunct from its position nearly opposite to a formidable whirlpool in the Menai strait, formed by theSwelley.roas, which rages with impetuous violence, and .of which the term. " Pwll,, 123 Gwy 11" is emphatically descriptive. The rocks, most of which are visible at low water, obstruct the channel of the strait, and when the lower are covered,. the tide, rushing between them with tremendous fury, forms numerous vortices and strong eddies, exceedingly dangerous to vessels navigating this part of the Menai, which are sometimes caught by the rapidity of the current, and dashed against the rocks that appear above the surface. The difficulty of avoiding this impending danger at certain states; of the tide, and the roaring noise and, violent agita-. don of the waters, have obtained for this part of the strait the appellation of the Scylla and Charybdis of Welsh mariners, of similar import with its Welsh name Pwll Ceris. At high water this terrific agitation subsides, and the appearance of the surface is smooth and tranquil, differing in no respect from the other parts. of the strait. The parish, which is of inconsiderable extent, is, situated on the western shore. of. the Menai strait,. and by. far the greater portion of it is inclosed and cultivated:: the surrounding scenery is marked with. features of rugged and romantic grandeur; and the views over the Menai, which this-place forms a noble bend, and of the adjacent country, combine. much picturesque beauty and.many interesting objects. On the summit of a craggy eminence to the-north. of the great Holyhead road, which passes: through. the parish; is a lofty column, erected by the inhabitants of the counties. of Anglesey and Carnarvon, to the honour of their countryman, Henry William, the present Marquess of Anglesey: on. the. north, side of the base is an appropriate inscription, commemorating the exploits - of that gallant com, mender,. durin the. campai n in Spain, in the year 1815. The village is situated on the new line of read' from London to Holyhead, and at no great distance from the Menai bridge; the inhabitants are partly employed in agriculture, and partly in 801110-1 extensive quarries, which are worked with considereble advantage to the proprietors. The stone dug in these quarries is a compact scbistus of good - quality, and inconsiderable demand; and every facility is:afforded for .ita. exportation by the Menai, on the shore of which a commodious wharf' has beencoustructed.t The living is a rectory, with the perpetual curacy of Llandysillio annexed, rated. in the king's hooks at £6. 15.; present net income, £228, with a glebe- house; patron, Bishop of Bangor. The church is a small. dark. edifice, in a.greatly -dilapidated. condition.. There. are as of worship. for Calvinistic and Wesleyan Meta About, 40 boys 40 girls. are instructed in three day schools, at the expense of their. parents; and there are two .

Two other donors, unknown, gave respectively £5 and £2. 10., the latter to be distributed in bread among the poor; but about twenty years since these sums, with other monies of the parish, were expended in erecting eight small houses, with gardens attached, in which poor families are allowed to reside rent-free. In a field near Ti-Mawr are the remains of a large cromlech, partly thrown down, the table stone of which now lies upon stones that formerly supported it from theground.
