The monument includes a bowl barrow situated on the crest of a ridge facing south-west in an area of undulating chalk downland. The barrow has a mound 20m in diameter and 1m high surrounded by a ditch from which material was quarried during the construction of the monument. Having become partially infilled over the years, the ditch is now only visible as a slight depression to the south-west of the mound; the remainder survives as a buried feature c.3m wide. The barrow was recorded as 'Stumleburgh' in a land grant of 1289.
