context_page_description: Glamorgan, or sometimes Glamorganshire, is one of the thirteen historic counties of Wales and a former administrative county of Wales. Originally an early medieval petty kingdom of varying boundaries known as Glywysing. Then taken over by the Normans as a lordship. 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 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.
context_section_description: Glamorgan's terrain has been inhabited by humankind for over 200,000 years. Climate fluctuation caused the formation, disappearance, and reformation of glaciers which, in turn, caused sea levels to rise and fall. At various times life has flourished, at others the area is likely to have been completely uninhabitable. Evidence of the presence of Neanderthals has been discovered on the Gower Peninsula. Whether they remained in the area during periods of extreme cold is unclear. Sea levels have been 150 metres (490 ft) lower and 8 metres (26 ft) higher than at present, resulting in significant changes to the coastline during this period.
  Archaeological evidence shows that humans settled in the area during an interstadial period. The oldest known human burial in Great Britain – the Red Lady of Paviland – was discovered in a coastal cave between Port Eynon and Rhossili, on the Gower Peninsula. The 'lady' has been radiocarbon dated to c. 29,000 years before present (BP) – during the Late Pleistocene – at which time the cave overlooked an area of plain, some miles from the sea.
  From the end of the last ice age (between 12,000 and 10,000 BP) Mesolithic hunter-gatherers began to migrate to the British Peninsula – through Doggerland – from the European mainland. Archaeologist Stephen Aldhouse-Green notes that while Wales has a "multitude" of Mesolithic sites, their settlements were "focused on the coastal plains", the uplands were "exploited only by specialist hunting groups".
  Human lifestyles in North-West Europe changed around 6000 BP; from the Mesolithic nomadic lives of hunting and gathering, to the Neolithic agrarian life of agriculture and settlement. They cleared the forests to establish pasture and to cultivate the land and developed new technologies such as ceramics and textile production. A tradition of long barrow construction began in continental Europe during the 7th millennium BP – the free standing megalithic structures supporting a sloping capstone (known as dolmens); common over Atlantic Europe. Nineteen Neolithic chambered tombs (or long barrows) and five possible henges have been identified in Glamorgan. These megalithic burial chambers, or cromlechi, were built between 6000 and 5000 BP, during the early Neolithic period, the first of them about 1500 years before either Stonehenge or the Egyptian Great Pyramid of Giza was completed. Two major groups of Neolithic architectural traditions are represented in the area: portal dolmens (e.g. St Lythans burial chamber (Vale of Glamorgan), and Cae'rarfau (near Creigiau)); and Severn-Cotswold chamber tombs (e.g. Parc Cwm long cairn, (Parc le Breos Cwm, Gower Peninsula), and Tinkinswood burial chamber (Vale of Glamorgan)), as well as tombs that do not fall easily into either group. Such massive constructions would have needed a large labour force – up to 200 men – suggestive of large communities nearby. Archaeological evidence from some Neolithic sites (e.g. Tinkinswood) has shown the continued use of cromlechi in the Bronze Age.
  
  The Bronze Age – defined by the use of metal – has made a lasting impression on the area. Over six hundred Bronze Age barrows and cairns, of various types, have been identified all over Glamorgan. Other technological innovations – including the wheel; harnessing oxen; weaving textiles; brewing alcohol; and skillful metalworking (producing new weapons and tools, and fine gold decoration and jewellery, such as brooches and torcs) – changed people's everyday lives during this period. Deforestation continued to the more remote areas as a warmer climate allowed the cultivation even of upland areas.
  By 4000 BP people had begun to bury, or cremate their dead in individual cists, beneath a mound of earth known as a round barrow; sometimes with a distinctive style of finely decorated pottery – like those at Llanharry (discovered 1929) and at Llandaff (1991) – that gave rise to the Early Bronze Age being described as Beaker culture. From c. 3350 BP, a worsening climate began to make agriculture unsustainable in upland areas. The resulting population press
