Clandon House, a Palladian architecture mansion, is in the village, a house, hosting dedicated visit days and weddings, entirely run by The National Trust. Clandon Park is not part of the National Trust. Clandon Park is a 1000-acre agricultural Estate that is the Seat of the Earls of Onslow and is currently owned and managed by Rupert Charles William Bullard Onslow, 8th Earl of Onslow. George Duncumbe owned it from 1615 until 1642 on its gradual sale to Sir Richard Onslow starting with the large lodge in the park in 1642, and a series of transactions with the Onslow family, begun in 1650, was finally concluded in 1711 by the transference of the manor to Sir Richard Onslow, a mild Roundhead (Parliamentarian).
