Devon (pronounced /ˈdɛvən/) is a large county in England. The county is also referred to as Devonshire, although that is an unofficial name, rarely used inside of the county itself and often indicating a traditional or historical context. The county shares borders with Cornwall to the west and Dorset and Somerset to the east. Its coastline follows the English Channel to the south and the Bristol Channel to the north.
Devon is the third largest of the English counties and has a population of 1,109,900. The county town is the cathedral city of Exeter and the county contains two independent unitary authorities: the port city of Plymouth and the Torbay conurbation of seaside resorts, in addition to Devon County Council itself. Plymouth is also the biggest city in Devon. Much of the county is rural (including national park) land, with a low population density by British standards. It contains Dartmoor 954 km2 (368 square miles), the largest open space in southern England [1].
The county is home to part of England's only natural UNESCO World Heritage Site, the Dorset and East Devon Coast, known as the Jurassic Coast for its geology and geographical features. Along with its neighbour, Cornwall, Devon is known as the "Cornubian massif". This geology gives rise to the landscapes of Dartmoor and Exmoor, which are both national parks. Devon has seaside resorts and historic towns and cities, and a mild climate, accounting for the large tourist sector of its economy.
