A mound may have preceded the present medieval Norman structure. The polygonal keep was the notable feature of the castle. Attached to it was a large squat building. A curtain wall, interspersed with towers, surrounded the castle. There is a moat or ditch constructed around the castle. Today, the site is surrounded by trees while the ruins are seldom visible from the road except in winter. The earliest extant drawing of the castle by Francis Place also shows it in ruins, but somewhat less dilapidated than at present.
