Enclosure 3, which was located at the northern end of Plateau 1, consisted of two arcing ditch segments forming a sub-circular or possibly ‘D’-shaped enclosure approximately 37.5m across internally north-south and in excess of 26m east-west. Four burials and a circular feature containing a small amount of cremated bone were discovered within the enclosure. The date and function of the enclosure is not clear but it is likely that it predates the beaker burials which are positioned within the area it encompasses, a late Neolithic or early Bronze Age date is therefore suggested.
