Wrexham ( REKS-əm; Welsh: Wrecsam; Welsh pronunciation: [ˈrɛksam]) is a large market town and the administrative centre of the Wrexham County Borough in Wales. It is located between the Welsh mountains and the lower Dee Valley alongside the neighbouring English county of Cheshire. Historically part of Denbighshire, the town became part of Clwyd in 1974 and has been the principal centre of Wrexham County Borough since 1996.
Wrexham has historically been one of the primary settlements of Wales. At the 2011 Census, it had a population of 65,692, making it the fourth largest urban area in Wales and largest in north Wales. The town comprises the local government communities of Acton, Caia Park, Offa, and Rhosddu. A wider urban area extends into villages like Coedpoeth, Llay, Gresford, and Rhosllanerchrugog.
Wrexham was likely founded prior to the 11th century and in the Middle Ages developed as a regional centre for trade and administration. The market town became the most populous settlement in Wales in the 17th century and was at the forefront of the Industrial Revolution from the 18th century. Prior to de-industrialisation in the 20th century, the town and surrounding area were a hub of coal and lead mining; the production of iron, steel and leather; and brewing.
