Somewhere on the fairways of Kildare Golf Course, at the north-western edge of the Little Curragh, a cluster of ancient burial monuments has been slowly disappearing into the landscape. At least twelve ring barrows, the modest graves of prehistory, each consisting of a low earthen bank encircling a shallow ditch, once sat on a gentle south-easterly slope here. Ring barrows are a common enough burial form across Ireland, typically Bronze Age in origin, but this group is unusual partly for its setting and partly for how thoroughly it has been swallowed up. Whins, the dense thorny scrub also known as gorse, have colonised the area to the point where the monuments are no longer clearly visible at ground level. What survives is, in the most literal sense, underfoot and out of sight.

The group was described in 1989 as at least twelve small circular enclosures, each averaging roughly six to ten metres in diameter, defined by a very shallow fosse, that is a surrounding ditch, and a low outer earthen bank no more than ten centimetres high. Even then they were difficult to read on the ground, obscured by tree and furze stumps and disturbed by sheep. A 1970 aerial photograph, referenced as CUCAP BDU 21, captured up to twelve of these circular forms clustered to the south and south-east of a larger enclosure nearby. A second aerial photograph, its date and origin uncertain, showed the features with even greater clarity. From above, they were legible; from the ground, they were already fading. One barrow, lying ten metres south of the adjacent enclosure, has been measured more precisely: a sub-circular area roughly 6.6 metres north to south and 5.8 metres east to west, enclosed by a ditch between 0.9 and 1.5 metres wide and an outer bank bringing the total external diameter to around thirteen metres. Complicating the picture further, some of the circular features may not be burial monuments at all, but lunging rings, small circular enclosures historically used for exercising horses, a plausible alternative given the Curragh's long association with equestrian activity.
