Wicklow, a maritime county of Leinster, borders on Dublin, Carlow, Kildare, and Wexford. Its greatest length is 40 miles, and greatest breadth 33; the area being 781 sq. m., or 500,178 acres, of which 118,000 are under tillage. The coast-line, in many parts precipitous, is obstructed by sandbanks. The Wicklow Mountains culminate in Lugnaquilla (3039 feet), and the glens are exceedingly picturesque, especially Glen-dalough, Glendalure, Imail, the Glen of the Downs, and Avoca. Some plains lie on the eastern and southern shores. The lakes, although strikingly beautiful, are few and small; and the rivers are mountain-streams, except the Liffey and the Slaney, which rise in Wicklow. Lead, copper, sulphur, and iron are raised, with some silver; a little gold has been found. Slates, limestone, and marl are likewise wrought. The fisheries are neglected; and the manufacture of flannels is nearly extinct. The county is divided into eight baronies. The principal towns are Wicklow, the capital, part of Bray, and Arklow. The county returns two members. Pop. (1841) 126,162; (1881) 70,386; (1901) 60,824, of whom 48,083 were Catholics. Wicklow was in 1605 erected into a separate county. It has many Celtic and ecclesiastical remains, at Glendalough (q.v.), etc. - The county town, Wicklow, at the Vartry's mouth, 28 miles ESE. of Dublin, attracts many visitors for sea-bathing. Pop. 3283.
