 It has been considered to be a burial mound or tumulus.When the stone ramparts were removed in the 1890s an oblong cavity was uncovered in the centre that extended across the entire top of the mound and was about 6 ft to 8 ft in width and depth.The walls were of neatly built drystone construction devoid of cement or mortar and the interior was filled with fallen earth and stones with no indication of what had formed the roof.
