DOLGELLEY, a market-town of North Wales, Merionethshire; situated on the Wnion, in a wide and fertile valley at the foot of the majestic mountain Cader Idris, 18 miles S.W. of Bala. The town is very irregularly built, and many of the older buildings are mean and unsightly; but these are gradually giving place to modern erections of a superior class. The Wnion is here crossed by a neat stone bridge of seven arches, erected in 1638; and a small stream, the Aran, descending from the Cader Idris, flows through the town. The church is a spacious edifice, standing on an eminence in the centre of the town, but with no pretensions to architectural beauty. It has a large tower, and contains some handsome monuments. The other principal buildings are the county hall, county gaol, old parliament house, and national school. Market-days—Tuesday and Saturday. Its manufactures are chiefly coarse woolen cloths and flannels. Pop. (1851) 2041.
