Coatbridge... is a town in North Lanarkshire, Scotland, about 8 1⁄2 miles (13.5 kilometres) east of Glasgow city centre, set in the central Lowlands. The town, with neighbouring Airdrie, is part of the Greater Glasgow urban area. While the earliest known settlement of the area dates back to the Stone Age era, the founding of the town can be traced to the 12th century, when a Royal Charter was granted to the monks of Newbattle Abbey by King Malcolm IV. Coatbridge, along with its neighbour Airdrie, forms the area known as the Monklands (population approximately 90,000 including outlying settlements). Quoted from Wikipedia
