The survey was based upon the principle that past human activity and its associated debris usually creates slight but persistent changes in the local magnetic environment. Both topsoil magnetic measurements and localised magnetometer survey were employed. The survey produced a single ephemeral anomaly, curvilinear and magnetically negative in nature, which was seen to correspond in part with a subtle topographic hollow. A zone of disturbed ground along the northern extremity of the sports field was also apparent; the nature of these signals, which were dominated by ferrous and other highly magnetic material, suggests this disturbance to be of relatively recent origin.

A number of new features were recorded of probable Romano - British date. In addition a small ring ditch, possibly Beaker period was also identified.

The relationship between the earthworks and interior are magnetically well defined. The site is within the Larkhill military training area and is relatively well preserved i.e. the site has seen minimal agricultural activity.

In the present work, we prove analytically that the aforementioned construction yields as a byproduct, an extremely accurate method for approximating a regular heptagon, and we quantify the accuracy that prehistoric surveyors may have ideally attained using simple pegs and ropes. We compare this method with previous approximations, and argue that it is likely to be at the same time the simplest and most accurate. Implications of our findings are discussed.

Key results of the survey included a large number of potential pits of unknown date both inside and outside the Neolithic enclosure circuits, an element of possible Bronze Age field system abutting the enclosure, and a second ring ditch within one of the adjacent Early Bronze Age round barrows.
