Ring-ditches of this kind are typically the eroded remains of prehistoric burial monuments, the outer ditches of round barrows or similar earthworks whose above-ground mounding has long since been ploughed flat. What survives is essentially a negative impression in the soil, revealed only when differential moisture or crop growth betrays the line of a long-filled trench.

All four were identified as cropmarks on a single aerial photograph taken on 20 August 1991. The one catalogued here measures approximately 20 metres in diameter, and its three companions lie to the north and north-west at distances of roughly 50 metres, 110 metres, and 240 metres respectively, suggesting a loose prehistoric grouping rather than an isolated monument. Since that photograph was taken, the R693 road has been constructed along a north-west to south-east line that cuts directly between the four sites, placing two of them to the east and two to the west. The road has introduced a modern division into what was once a single coherent cluster, and any subsurface archaeology that lay in its path will have been disturbed or destroyed in the process.
