WIGVAIR-with-MERIADOG (GWYG-FAIR), a township, in that part of the parish of ST-ASAPH which is in the hundred of ISDULAS, county of DENBIGH, NORTH WALES, 2 miles (S.) from St. Asaph; containing 586 inhabitants, of whom 257 are in Wigvair. This township is situated on the left bank of the Elwy, and contains near that river a beautiful and romantic dingle, in which is a fine spring, called Y Fynnon Vair, or " the Well of Our Lady," discharging about one hundred gallons of water per minute, and strongly impregnated with lime. It is inclosed in a richly sculptured polygonal basin, which was formerly covered by a canopy supported by ornamental pillars, and was then numerously resorted to as a cold bath. Adjoining the well are the ruins of a cruciform chapel, in the decorated English style, the fine remains of the windows and other parts being overgrown with ivy: prior to the Reformation, this was a chapel of ease to St. Asaph, and was served by one of the vicars of that church. The river Elwy, the banks of which are finely wooded, is here crossed by a majestic bridge, called Pont-yr-Allt-Glich, of one arch, eighty-five feet in span. Wigvair was formerly assessed in conjunction with the -hamlet of Meriadog for the separate support of the poor, but it is now included in the general assessment of the parish for that purpose: the rateable annual value returned for the two places is £2298.
