Cropmarks of probable prehistoric or Roman enclosures, to the south-west of Audleby Low Covert, Grasby. Visible as two conjoined, ditched rectilinear features, measuring roughly 55m by 30m and 45m by 45m. The more northerly of the two enclosures contains a further, smaller enclosure in its eastern corner, measuring roughly 10m by 10m.
