Earthworks of medieval ridge and furrow, to the south of Rye Hill Plantations, Brocklesby. Visible as a series of parallel linear earthworks, aligned on a roughly north-east to south-west alxis, on both the Google Maps aerial imagery and on recent LiDAR data. The earthworks have been bisected by a 20th century pond, but do survive underneath a small 20th century tree plantation at the southern end of the field. {1}{2}
