The site is described as a strong hilltop camp covering 20 acres (8.1 ha), with a single bank and ditch, and has commanding views over the surrounding area.

[2] Only the southwest rampart (which includes the original entrance) is in National Trust ownership; the rest is private land.

[1] There are a number of other archaeological sites in the area, including a Bronze Age bowl barrow mound of approximately 130 ft (40 m) in diameter and 4 ft 11 in (1.5 m) in height at grid reference SU395363 and recorded in an Anglo-Saxon charter as Heardulfe's Hlaewe or Heardulfe's Barrow.

Whilst there are 17 white horse hill figures in England, with nine being nearby in Wiltshire, this is the only example in Hampshire.

[6] There was also a hill figure of a cross nearby, only a few yards from Winchester Road, constructed using the same method.
