Cropmarks and soilmarks of a Neolithic long barrow, to the east of North Willingham. The long barrow is situated on the summit of the main west escarpment of the Wolds, overlooking the valley of a tributary if the River Rase to the south. It is aligned east-north-east to west-south-west, with the long axis traversing the contours. It is a trapeziform enclosure with convex terminals, measuring 29m by 11m (tapering to 8m). A secondary ring ditch measuring 16m in diameter and thought to be the remains of a Bronze Age round barrow straddles the middle (see MLI126980). Soilmarks of former ridge and furrow cultivation extends across the site. {1}{2}{3}{4} Further analysis of the aerial photographic evidence show the remains of the long barrow as cropmarks and soilmarks, with traces of a shallow earthwork also possibly surviving. The barrow is roughly oval in plan, elongated west to east with maximum visible dimensions measuring 36.5m by 19.5m. It is uncertain whether the low spread earthwork mound is from the later round barrow or the long barrow, or possibly even both. {5}{6}{7}
