This iron age hillfort is reached by a minor road off the B4005 or alternatively across open downland by foot. It is adjacent to the Ridgeway and close to a Celtic field system known as Burderop Down. The oval site covers over 11 acres (around 4.7 hectares) and is enclosed by two banks and ditches, plus other defences which may have been added later. Tools, weapons and chariot parts have been found here. At a later time it may have been the site of Cinric and Ceawlin's victory over the Brittons at Beran Byrig in 556.
