What was uncovered in 2003 was not a single monument but a cluster: a ring-ditch, a cremation pit, and two small circular structures arranged across the ground in a pattern that speaks, quietly, to organised prehistoric activity on this low-lying coastal plain.

A ring-ditch is the surviving trace of a circular earthwork, usually a barrow or funerary enclosure, where the surrounding ditch has outlasted whatever mound once rose above it. The example at Charlesland was modest in scale, its ditch about 1.4 metres wide and 0.6 metres deep on average, enclosing a near-circular area roughly 5.5 metres across. Nine flint finds came from the ditch itself. Just over three metres to the north-east lay a cremation pit containing deposits of cremated bone, charcoal, and large stones, suggesting that burial or commemoration of the dead took place in close proximity to the enclosure. Ten metres to the west, excavators uncovered a small circular structure about three metres in diameter, its outline defined by a narrow slot-trench, a central post-hole, and an outer ring of post-holes; two post-holes marked what appeared to be an entrance roughly 0.9 metres wide. Fragments of prehistoric pottery were recovered from this outer ring. An eleventh metres further north, a second circular structure of similar scale was defined by post-holes and stake-holes arranged around a shallow central depression. The excavation was carried out under licence in advance of the construction of the dual carriageway from the R671 to Greystones, and the findings were published by Molloy in 2006. The site now lies beneath the road corridor, its physical remains no longer accessible, but preserved in the archaeological record of a moment when infrastructure and prehistory briefly intersected.
