Manor Farm, East Kennett, Wiltshire: Report on Geophysical Surveys, August 2020
Author(s): Neil Linford, Paul Linford, Andy Payne
Caesium magnetometer and Ground Penetrating Radar (GPR) surveys were conducted at Manor Farm, East Kennett, Wiltshire, to investigate a recently collapsed void in an agricultural field exposing a probable megalithic square chamber formed from sarsen boulders. Results from the vehicle-towed caesium magnetometer survey (2.3 ha) were partly obscured by ferrous interference from farm buildings and two pipes, but revealed a series of ditch-type anomalies suggestive of a field or enclosure system. This activity appears to be concentrated to the north of the field in the vicinity of the exposed sarsens. The GPR coverage (1.2 ha) provided some additional detail regarding the extent and depth of the sarsen structure and identified a number of similar, discrete anomalies in the survey area. A group of rectilinear anomalies, possibly representing buildings or structures with shallow surviving foundations, have also been revealed to the west of the exposed sarsens and, together with the field system, are suggestive of a small Roman agricultural settlement.
