Earthworks of medieval ridge and furrow, to the east of Manor House, Covenham St Bartholomew. Identified on aerial photographs dated to 1971, examined as part of the Lincolnshire Coastal Grazing Marsh project. {1} All of the ridge and furrow remains appear to have been removed by more recent agricultural ploughing, and no earthworks can now be discerned here on the Google Maps aerial imagery layer. {2}
