SDO21375 - Wimborne Showground, Lake Farm, Wimborne Minster, Dorset. Report on Geophysical Surveys, September 2024

'Caesium magnetometer (13.06ha) and Ground Penetrating Radar (GPR) (11.2ha) surveys were conducted over two fields located at Wimborne Showground, Lake Farm, Wimborne Minster, Dorset in response to a casework request from Historic England’s South West Regional Team to assess any possible damage that may have been caused to the scheduled remains of a Roman vexillation fort by a recent incident of mole-ploughing. A secondary aim of the project was to investigate the adjacent field to the north for any evidence of further buried archaeology. The caesium magnetometer survey confirms results from previous fluxgate gradiometer surveys over the scheduled monument and its surrounding environs, while the results from the GPR survey have identified the extent and estimated depth of the mole-ploughing and suggest it may be deep enough to impinge on the upper layers of the underlying archaeological remains.'
