The site is described as a strong hilltop camp covering 20 acres, with a single bank and ditch, and has commanding views over the surrounding area. The bank and ditch are well preserved to the west, the bank being 9 feet (2.7 m) high and 16 feet (4.9 m) above the bottom of the ditch. The eastern side has been ploughed out, and the ditch only remains to the north and south. The entrance is on the western side; the interior is down to permanent pasture.[2] Only the southwest rampart (which includes the original entrance) is in National Trust ownership; the rest is private land.[3]
The site is designated as a scheduled monument.[1]
There are a number of other archaeological sites in the area, including a Bronze Agebowl barrow mound of approximately 40m in diameter and 1.5m in height at grid referenceSU395363 and recorded in an Anglo-Saxon charter as Heardulfe's Hlaewe or Heardulfe's Barrow.[2][4][5] The area is now subject to ploughing. In addition, several other tumuli are to be found south of the hillfort.
On the southern ramparts of Woolbury Ring is a hill figure of a horse. Whilst there are 17 white horse hill figures in England, with nine being nearby in Wiltshire, this is the only example in Hampshire. The horse was constructed crudely of rough flints, painted white and pushed into the ground to form the shape of the horse. The earliest documentation of the horse is in 1846. The horse for many years was covered by the surrounding bushes but in 1999, the site was cleared so the horse become visible again.[6]
There was also a hill figure of a cross nearby, only a few yards from Winchester Road, constructed using the same method.[7] This was lost in 1944.[8]
