Greenwood's map of 1820 shows the copse named as Robin Hood's Ball and the enclosure as Neath Barrow.
A causewayed enclosure consists of a circuit of ditches dug in short segments, leaving 'causeways' passing between them to the centre.
If it is assumed that the area was free of woodland in the Neolithic period, then its position on a low hill would have afforded clear views of the plain in all directions, and the site of Stonehenge would have been visible, although it is likely that the enclosure predates it by some time.
Though Robin Hood's Ball has never been comprehensively excavated and its use is unclear, it has been suggested that these camps may have served as centres or rally points for a fairly wide area, where tribal ceremonies could be performed.
The site was constructed at a time of transition from hunter-gatherer to permanent settlement during the Neolithic Revolution, and the relatively even spacing of causewayed enclosures across the south indicates that they may have been the central points of tribes or communities.
