or HARLEICH, a town of Merionethshire, in North Wales, 223 miles from London, on the sea coast, near the north-west point of the county. It is naturally strong, a garrison being kept here for the security of the coast. Its castle lies now in ruins. The town, though a corporation and governed by a mayor, makes but a very mean appearance. It has a market on Saturdays, and four fairs in the year.
