Wadhurst Castle is a 19th-century castellated mansion in East Sussex built in 1818-20 by James Louis West on the site of the medieval farmhouse Maplehurst. Remodelled by architect Edward Buckton Lamb for Benjamin Harding in 1838, this Grade II listed building sits elevated overlooking the surrounding countryside on a 140-acre private estate. Today it operates as a versatile event venue hosting weddings, conferences, and corporate functions, featuring the restored Carriage Barn with capacity for up to 104 guests. Its setting in an area of outstanding natural beauty and appearances in television productions have enhanced its cultural significance as a distinctive example of Regency castellated architecture adapted for contemporary hospitality.
