Until 1974, Glamorgan (), or sometimes Glamorganshire (Welsh: Morgannwg [mɔrˈɡanʊɡ] or Sir Forgannwg [ˈsiːr vɔrˈɡanʊɡ]), was an administrative county in the south of Wales, and later classed as one of the thirteen historic counties of Wales. Originally an early medieval petty kingdom of varying boundaries known in Welsh as Morgannwg (or Glywysing), which was then invaded and taken over by the Normans as the Lordship of Glamorgan. The area that became known as Glamorgan was both a rural, pastoral area, and a conflict point between the Norman lords and the Welsh princes. It was defined by a large concentration of castles. After falling under English rule in the 16th century, Glamorgan became a more stable county, and exploited its natural resources to become an important part of the Industrial Revolution. Glamorgan was the most populous and industrialised county in Wales, and was once called the "crucible of the Industrial Revolution", as it contained the world centres of three metallurgical industries (iron, steel and copper) and its rich resources of coal. Under the Local Government Act 1972, the county boroughs and administrative county of Glamorgan were abolished on 1 April 1974, with three new counties being established, each containing a former county borough: West Glamorgan, Mid Glamorgan, South Glamorgan. The name also survives in that of Vale of Glamorgan, a county borough. Glamorgan comprised distinct regions: the industrial valleys, the agricultural vale and the scenic Gower Peninsula. The county had boundaries with Brecknockshire (north), Monmouthshire (east), Carmarthenshire (west), and to the south it was bordered by the Bristol Channel. The total area was 2,100 km2 (811 sq mi). Glamorgan contained two cities, Cardiff, the county town and from 1955 the capital city of Wales, and Swansea. The highest point in the county was Craig y Llyn (600 metres (2,000 ft)) which was situated near the village of Rhigos in the Cynon Valley.
