Silbury Hill, Wiltshire : Report on Geophysical Surveys, 2005-2008
Author(s): Paul Linford, Neil Linford, Louise Martin, Andy Payne
A series of geophysical survey visits were made between February 2005 and February 2008, to investigate the immediate environs of Silbury Hill, Wiltshire. The impetus for the survey was to assist with the location of a works compound required for remedial repairs to the monument, begun in 2007, following the partial collapse of earlier investigative tunnels dug into the hill. The survey area initially covered with a high-sensitivity caesium magnetometer array was subsequently expanded and successfully revealed a wealth of anomalies, including what appears to be a larger Roman settlement at the site than had previously been recognised. Additional areas of earth resistance and ground penetrating radar were also conducted to investigate specific anomalies, some thought to be masonry building structures. Finally, an attempt was made to profile sections through the ditch surrounding the monument with a combination of earth resistance tomography and radar transects.
