context_page_description: Somerset is a county in South West England which borders Gloucestershire and Bristol to the north, Wiltshire to the east, Dorset to the south-east and Devon to the south-west. It is bounded to the north and west by the Severn Estuary and the Bristol Channel, its coastline facing southeastern Wales. Its traditional border with Gloucestershire is the River Avon. Somerset's county town is Taunton.
  Somerset is a rural county of rolling hills, the Blackdown Hills, Mendip Hills, Quantock Hills and Exmoor National Park, and large flat expanses of land including the Somerset Levels. There is evidence of human occupation from Paleolithic times, and of subsequent settlement by the Celts, Romans and Anglo-Saxons. The county played a significant part in Alfred the Great's rise to power, and later the English Civil War and the Monmouth Rebellion. The city of Bath is famous for its Georgian architecture and is a UNESCO World Heritage Site.
context_section_description: The Somerset Levels (or Somerset Levels and Moors as they are less commonly but more correctly known) are a sparsely populated wetland area of central Somerset, between the Quantock and Mendip hills. They consist of marine clay levels along the coast, and the inland (often peat based) moors. The Levels are divided into two by the Polden Hills. Land to the south is drained by the River Parrett while land to the north is drained by the River Axe and the River Brue. The total area of the Levels amounts to about 647.5 square kilometres (160,000 acres)
  and broadly corresponds to the administrative district of Sedgemoor but also includes the south west of Mendip district. Approximately 70% of the area is grassland and 30% is arable.
  Stretching about 32 kilometres (20 mi) inland, this expanse of flat land barely rises above sea level. Before it was drained, much of the land was under a shallow brackish sea in winter and was marsh land in summer. Drainage began with the Romans, and was restarted at various times: by the Anglo-Saxons; in the Middle Ages by the Glastonbury Abbey, during 1400–1770; and during the Second World War, with the construction of the Huntspill River. Pumping and management of water levels still continues.
  The North Somerset Levels basin, north of the Mendips, covers a smaller geographical area than the Somerset Levels; and forms a coastal area around Avonmouth. It too was reclaimed by draining. It is mirrored, across the Severn Estuary, in Wales, by a similar low-lying area: the Caldicot and Wentloog Levels.
  In the far west of the county, running into Devon, is Exmoor, a high Devonian sandstone moor, which was designated as a national park in 1954, under the 1949 National Parks and Access to the Countryside Act.
  The highest point in Somerset is Dunkery Beacon on Exmoor, with an altitude of 519 metres (1,703 feet).
  Over 100 sites in Somerset have been designated as Sites of Special Scientific Interest.
