SNN116668 - Green Hill Solar Project, Site F, Northamptonshire: Geophysical Survey- interim report

A geophysical (gradiometer) survey was undertaken on approximately 166 out of 292 hectares of land associated with Site F of the Green Hill Solar Project, Grendon, Northants. Archaeological and possible archaeological responses have been recorded throughout. These comprise ring ditches, linear ditches and rectilinear enclosures, indicative of settlement activity over a probable prehistoric to medieval timeframe. The location of a previously excavated Roman villa is also apparently surrounded by field divisions. Uncertain anomalies recorded within the data may also have an anthropogenic origin. Former field boundaries have been recorded along with medieval/post-medieval ridge and furrow cultivation, modern ploughing and land drains. Magnetic disturbance within the dataset can be attributed to adjacent tracks, metal fencing within field boundaries, electricity pylons, overhead cables and demolition of a former brick works. Geological responses seen within the dataset reflect either the topography of the site, discrete pockets of natural variations or former watercourses. Based on the geophysical survey, the archaeological potential of this site is deemed to be high where there are areas of activity and low elesewhere.
