The Duchy of Cornwall is a private estate established in 1337 to provide income for the heir apparent to the British throne. It covers about 53,000 acres of land, primarily in Cornwall and Devon, and includes farms, residential properties, and commercial enterprises. The income generated supports the Duke of Cornwall, who is typically the eldest son of the reigning monarch. The current Duke of Cornwall is Prince William, following the accession of his father, King Charles III, to the throne. The Duchy is managed by the Duchy of Cornwall Estate, which aims to maintain and enhance the land while ensuring sustainable practices.
