The north-westernmost of three Bronze Age round barrows, to the east of Poke Holes, Calcethorpe. Visible as cropmarks showing a circular ditched enclosure measuring roughly 25m in diameter. Identified on aerial photography examined as part of the National Mapping Programme. {1}{2} The barrow lies in close proximity to another Bronze Age round barrow (see MLI127014) and a rectilinear enclosure (see MLI127016) to the east, and a Neolithic long barrow (see MLI43179) and a further Bronze Age round barrow to the south-east (see MLI127015). All of these features have been scheduled, with most in a main group including the intervening ground, with the southernmost barrow in a separate protected area. All of the features are visible as cropmarks on aerial photographs, showing as infilled and buried ditched features. Further features not revealed by aerial photography will also be preserved beneath the present ground surface. The fills of the ditches will contain rare and valuable artefactual and organic evidence, including human remains, relating to the construction, dating, periods of use and religious beliefs of the barrow builders. Environmental deposits preserved in the same features may illustrate the nature of the landscape in which the monument was set. The long barrow is a relatively unusual example displaying a U-shaped ditch thought to be indicative of abandonment before completion. The buried features and archaeological deposits contained therein may confirm this and will provide insights into the early constructional phases which are often obscured in more developed examples. Although the ditched enclosure cannot be dated, its location suggests a spatial relationship with the barrows. Its chronological relationship may be revealed by artefactual evidence from the interior, from the fills of its buried ditches and from the surrounding area. The proximity of the Bronze Age barrows to that of the earlier Neolithic long barrow suggests the location had enduring ritual significance. The long barrow is one of a group focussed on the prehistoric trackway now known as the Bluestone Heath Road, and on the valley of the Waithe Beck. Comparative evidence from all these barrows may have considerable significance for the study of communications, settlement and demography during the prehistoric period. {3} More recent analysis of the aerial photography for this area shows the bowl barrow as cropmarks and soilmarks of a circular enclosure, with an internal diameter of 23.5m. The barrow also shows as a low earthwork mound, on a digital elevation model derived from 2m gridded height data. {4}
