Visited 14.8.10 It certainly looked like a tumulus and the fact the top of the hill was fenced off perhaps supports this theory? There was no public access across the open fields so I settled for a view from the minor road just east of Littleton Upon Severn.
An oval mound approximately 80 feet by 60 feet by 3 feet. The edge rises abruptly from a “platform” path round the mound. Probably a tree circle, but may be a tumulus.
