Cropmarks of a probable Bronze Age round barrow, to the north-west of South Ormsby. Visible as a circular enclosure, defined by a single ditch measuring roughly 20m in diameter. Identified on aerial photography examined as part of the National Mapping Programme. {1} The round barrow was scheduled in April 2024, together with a group of three nearby long barrows (see MLI43651, MLI126959 and MLI126960) and an adjacent C-shaped enclosure of likely prehistoric date (see MLI128005). The survival of all these monuments as buried features had been confirmed by geophysical survey, conducted in 2018, along with the clearly defined cropmarks noted on aerial photography. All of the features here lie below the crest of the hill south of Bluestone Heath Road, and north of the valley of a small brook which eventually joins Calceby Beck. This round barrow is as described above, with the geophysical survey comfirming the complete circuit of the enclosing ditch. Valuable archaeological deposits will be preserved on the buried ground surface and in the fills of the ditches. These will provide rare information concerning the dating and construction of the monument and the sequence of mortuary practices at the site. The same deposits will also retain environmental evidence illustrating the nature of the landscape in which the monuments were set. The three long barrows, one round barrow and C-shaped ditched enclosure form a group. They are all situated within 90m of each other and demonstrate that there was considerable activity in this location in the Neolithic and Bronze Age period. They also form part of the wider significant group of long barrows in the Lincolnshire Wolds. {2}
