Earthworks of medieval ridge and furrow, to the north-west of Highfield House, Tetney. Visible as four conjoined blocks of parallel linear earthworks, forming part of a larger medieval field system. Identified on aerial photography examined as part of the National Mapping Programme. {1} All of the earthworks appear to have been destroyed by more recent agricultural activity, and no trace of them could be seen on either the Google Maps satellite imagery layer or on LiDAR data for this area. {2}{3}
