Cornwall is situated on the westernmost part of the South West Peninsula of Great Britain and is known for its spectacular landscape, unique history, and mild climate. It is one of the Celtic nations and is recognized as the homeland of the Cornish people. The windswept moorland interiors are commonly associated with Arthurian legend and the county's ancient Celtic roots. Cornwall's craggy coastline formed a vital part of the network of battlements which protected the British Coast. Ancient castles such as Saint Michael's Mount and St. Mawes Castle, Tintagel Castle, and seaside resorts dot the coastline. Cornwall is also known for its horticulture: from the 18th century Lost Gardens Heligan to the space-age Eden Project. Its windy sea makes it a popular destination for surfing and other watersports. Visitors may stay in authentic cottages preserved from ancient times, modern accommodations, and cozy inns available at every price point.
