Somewhere on the north-western fringe of the Little Curragh, on the grounds of Kildare Golf Course, a cluster of ancient burial mounds has been quietly disappearing beneath gorse and overgrowth for decades. Ring barrows are among the more unassuming monuments in the Irish archaeological landscape: low, circular earthworks, each defined by a shallow outer ditch (known as a fosse) and a modest enclosing bank, typically marking prehistoric burial sites. These particular examples are so slight, with estimated average diameters of roughly six to ten metres, banks no higher than ten centimetres, and fosses barely five to ten centimetres deep, that even when the vegetation was less dense they were difficult to pick out.

Aerial photography has done most of the work of revealing them. A 1970 photograph, catalogued as CUCAP BDU 21, shows up to twelve small circular enclosures arranged to the south and south-east of a larger enclosure nearby. A second photograph, of uncertain date and possibly from the Geological Survey of Ireland, makes the features even more legible from the air than the first. When a survey was carried out on the ground in 1989, investigators counted at least twelve ringbarrows, though even then the task was complicated by tree and furze stumps and by sheep poaching the soft earthen edges. Since then, the site has become almost entirely covered in whins, the dense prickly shrub also known as gorse or furze, and the monuments are no longer visible at ground level at all. There is an additional layer of ambiguity: some of the circular features may not be burial monuments at all, but lunging rings, the small circular enclosures once used for exercising horses on a long rein, which would be entirely in keeping with the Curragh's long association with equestrian activity.
