'Dam Close' appears to be two fortified enclosures with entrances on the north and south sides. The banks have been reduced in height to the north-west and end in a small hollow and subsidiary enclosure. To the south-east the area has been levelled. There are no signs of foundations within the enclosure. C.W. Phillips suggested that a small work to the west of the main enclosure may be a fishpond. He believed the work to be medieval in origin and to have similarities to a nearby enclosure at Claxby St Andrew (see MLI42078). {1}{2} Theories regarding the date and function of the monuemnt have varied, with William White in 1882 believing the site to be the remains of a Danish camp, whilst the surveyors of the 2nd edition 25" Ordnance Survey County Series map labelled the site as being the remains of a Roman camp. The consensus of more recent interpretation would suggest the site is of medieval origin, though no significant archaeological investigation has been conducted and this date remains tentative. The earthworks of the enclosure are clearly discernible on aerial photographs of this area, with the National Mapping Programme identifying the earthworks as the remains of a probable medieval enclosure or ringwork. A function of the earthwork as a possible stock enclosure, similar to that of the nearby enclosure at Claxby St Andrew, has also been suggested. {3}{4}{5}{6}
