Cropmarks of a rectilinear enclosure of unknown date, to the north of South Ormsby. Visible as three sides of a roughly rectilinear ditched enclosure, measuring roughly 55m by 50m. Identified on aerial photography examined as part of the National Mapping Programme. {1} The enclosure cropmarks were visible on later aerial photographs, taken of this area in June 2011. The cropmarks seem to lie partially beneath the remains of a former post-medieval plantation in this area, known as Washdyke Walk Plantation (see MLI126956).{2}
