Cornwall is a ceremonial county and unitary authority area 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.

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 attractive villages, 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.
