Longleat House was built in the sixteenth century by Sir John Thynn on the site of a dissolved priory, and in 1949 became the first stately home in Britain to be opened to the public on a commercial basis. The house, park and attractions are open from mid-February to the start of November each year. The 9,800-acre estate, of which the park occupies 900 acres, has long been one of the top British tourist attractions, and has motivated other large landowners to generate income from their heritage in response to rising maintenance costs. Longleat leases 400 acres of land to Center Parcs for the operation of the Longleat Forest holiday village.
