Evidence of Bronze Age inhabitation of Brimpton is in five round barrows right leading up to the border with Baughurst, Hampshire to the south. Known as "Borson Barrows", the tumuli were referred to in an Anglo-Saxon charter in AD 944. There have also been Iron Age and Roman settlements identified within the parish. The hypocaust of a villa was uncovered in the village, though records of its exact location no longer exist. One possible location is opposite Brimpton House near the parish church. A mediaeval bronze steelyard weight was found in the garden of the old moated house at Brimpton Manor.
