Devon (also known, far less commonly, as "Devonshire") is a large county in England's West Country, bordered to the west by Cornwall and to the east by Dorset and Somerset. Uniquely amongst English counties, Devon has two separate coastlines: to the south, on the English Channel and to the north, on the Celtic Sea and Bristol Channel. These are studded with resort towns, harbours and (more recently) surfing beaches. Devon is also home to two national parks - Dartmoor and Exmoor and includes the island of Lundy in the Bristol Channel/Celtic Sea.
The name "Devon" derives from the Celtic people who inhabited the southwest of Britain at the time of the Roman invasion, the Dumnonii. Devon's flag is green, with a black and white cross.
Devon has produced tin, copper and other metals throughout its history. Tin was found in the granite of Dartmoor, and copper in the areas around the moor. In the eighteenth century, Devon Great Consols mine (near Tavistock) was believed to be the largest copper mine in the world.
