Cropmarks of a probable prehistoric enclosure, to the south of Scamblesby. Visible as a roughly oval-shaped enclosure, defined by broad ditches of irregular width and with opposed entrances. Cropmarks of a pit approximately 8m in diameter lie a short distance to the north-east. The enclosure could possibly represent the remains of a henge but its irregularity and slightly odd shape make it different in form to known examples. Identified on aerial photography examined as part of the National Mapping Programme. {1}{2} This feature is thought to much more likely be the remains of a levelled Neolithic long barrow, located in the high Wolds. It lies below the crest of a west-facing slope of a spur, situated towards the head of a small valley of a minor tributary of the River Bain. It is aligned on a north-north-west to south-south-east axis, and is an elongated oval enclosure comprising two ditches of very arcuate form. The ditches are asymmetrical. The west arc has a slightly bulbous north terminal and a large pit-like feature at the south end. It lies in a typical long barrow position. It is not considered as belonging to a henge class. The barrow seems to be situated in a slight natural depression. A small pit-like feature lies to the immediate north-east. {3}{4}{5}
