Dragon Hill is a natural chalk hill with an artificial flat-top and is situated on the scarp slope of White Horse Hill. This spur of natural rock has been shaped for some unknown purpose in antiquity. It has been suggested as some sort of Iron Age ritual site associated with the nearby hill-figure.

Its sides have been steepened and its top leveled to make a drum shape. In the early nineteenth century Dragon Hill was thought to be a built feature such as a barrow, and the Saxons believed it was a barrow too, but when explored in 1852 it was concluded that it was a natural rock outcrop. Its projection well above the surrounding chalk slope nevertheless suggests that it is at least in part a built feature.'
