Cumbernauld, “new town,” North Lanarkshire council area, historic county of Dunbartonshire, central Scotland. Cumbernauld was designated a new town in 1956 to accommodate overspill population from Glasgow and has grown to become the largest town in the council area. The town is 14 miles (22 km) northeast of Glasgow in the centre of the Forth-Clyde valley, the main industrial belt of Scotland, with easy access to port facilities and the cities of Glasgow and Edinburgh. The exposed, sloping site, restricted by coal mining in the northwest and fireclay working in the southeast, made necessary high-density housing, unusual in a new town, linked by walkways to a hilltop multistoried town centre. Peripheral areas of flat land in the northeast and southwest are devoted to industry. Cumbernauld received national attention for its original and controversial design, its architectural adaptation to a difficult site, and its successful, almost total segregation of pedestrians and vehicles. It also succeeded in attracting both residents (mostly from Glasgow) and new industries. Pop. (2001) 51,670; (2011) 51,840.
