 A tall embattled wall, it is believed, ran round the top of the hill, turning behind the steward's house, and then behind the steward's gallery and around the keep.A 16th century sketch shows a four-sided, two-story gatehouse with a Norman round-headed doorway, the door including a wicket gate, a small part may be preserved in the wall to the east.Possibly similar the one at Tickhill, the upper floor may have served as a lodging for the castle porter who acted as the jailer.
