MOLA (Museum of London Archaeology) was commissioned to undertake an archaeological geophysical survey of c8ha of land at Hall Farm, Grendon, Northamptonshire. The survey identified medieval to early post-medieval ridge and furrow cultivation extending across almost the entire site. No other definite archaeological remains were detected, although a few anomalies at the south-western corner of the site could possibly be interpreted as pits and a short length of ditch.
