Louth. 1. A maritime county of the province of Leinster in Ireland, extending from the river Boyne to Carlingford, and having a coast-line on the Irish Sea. Its average width is 10 miles, and its area 202,000 acres, 40 per cent. of which is grassland. The surface generally is flat except in the neighbourhood of Carlingford, and the coast-line is low and sandy save where Clogher Head rises to a height of 180 feet. Cultivation is advanced, and good potatoes, oats, barley, and turnips are grown. Coarse linen is manufactured, and oyster and other fishing is carried on. The county returns two members to Parliament. Drogheda and Dundalk are important towns. The county is rich in Celtic and other antiquities, among which are the sculptured crosses at Monasterboice, round towers at Mopasterboice and Dromiskin, and ruins of abbeys in various places.
