 The outer bailey lay to the south-east of the surviving remains of the castle, but little is known about its shape or the buildings within it.The inner bailey survives as a low earth terrace, or mound, forming an irregular polygon up to across, protected by a curtain wall and a moat.Its curtain wall is high and almost wide, made of coursed flint rubble reinforced with mural timbers, with ironstone slabs in the putlog and drawbar holes used in its construction.
