Cornwall is a unitary authority and ceremonial county of England, within the United Kingdom. Cornwall is a peninsula bordered to the north and west by the Celtic Sea, to the south by the English Channel, and to the east by the county of Devon, over the River Tamar. Cornwall has a population of 536,000 and covers an area of 3,563 km2 (1,376 sq mi). The administrative centre, and only city in Cornwall, is Truro, although the town of St Austell has a larger population.
Historically tin mining was important in the Cornish economy, becoming increasingly significant during the High Middle Ages and expanding greatly during the 19th century when rich copper mines were also in production. In the mid-19th century, however, the tin and copper mines entered a period of decline. Subsequently china clay extraction became more important and metal mining had virtually ended by the 1990s. Traditionally fishing (particularly of pilchards), and agriculture (particularly of dairy products and vegetables), were the other important sectors of the economy. The railways led to the growth of tourism during the 20th century, however, Cornwall’s economy struggled after the decline of the mining and fishing industries. The area is noted for its wild moorland landscapes, its long and varied coastline, its many place-names derived from the Cornish language, and its very mild climate. Extensive stretches of Cornwall’s coastline, and Bodmin Moor, are protected as an Area of Outstanding Natural Beauty.
Tourism is estimated to contribute up to 24% of Cornwall’s gross domestic product. Cornwall’s unique culture, spectacular landscape and mild climate make it a popular tourist destination, despite being somewhat distant from the United Kingdom’s main centres of population. Surrounded on three sides by the English Channel and Celtic Sea, Cornwall has many miles of beaches and cliffs; the South West Coast Path follows a complete circuit of both coasts. Other tourist attractions include moorland, country gardens, museums, historic and prehistoric sites, and wooded valleys. Five million tourists visit Cornwall each year, mostly drawn from within the UK. Visitors to Cornwall are served by airports at Newquay and Exeter, whilst private jets, charters and helicopters are also served by Perranporth airfield; nightsleeper and daily rail services run between Cornwall, London and other regions of the UK. Newquay and Porthtowan are popular destinations for surfers. In recent years, the Eden Project near St Austell has been a major financial success, drawing one in eight of Cornwall’s visitors.
Other industries are fishing, although this has been significantly re-structured by EU fishing policies (the Southwest Handline Fishermen’s Association has started to revive the fishing industry), and agriculture, which has also declined significantly. Mining of tin and copper was also an industry, but today the derelict mine workings survive only as a World Heritage Site. However, the Camborne School of Mines, which was relocated to Penryn in 2004, is still a world centre of excellence in the field of mining and applied geology and the grant of World Heritage status has attracted funding for conservation and heritage tourism.
