The Castle is set in 480 acres of parkland, once part of a vast medieval deer park. It is notable for the sunken ditches or ‘ha-has’ installed to stop the deer from entering the formal gardens but avoiding using fences so as not to spoil the view from the castle. The property is well known for its gardens, with clipped yew hedges, herbaceous borders, rock gardens and terraces and surrounded by 18th century parkland. Offa's Dyke passes within some 200 yards of the castle.
