Spread across a gentle south-facing slope on the Curragh, a group of ancient burial mounds sits so quietly in the landscape that their presence only became properly documented through aerial photography. What makes this cluster unusual is not any single monument but the arrangement itself: up to eleven low earthen mounds, the majority forming a gently curving line roughly eighty metres long on a northwest-to-southeast axis, with two further mounds sitting apart at either end like loose punctuation marks.

Ditch barrows, sometimes called disc barrows, are a form of prehistoric funerary monument in which a central mound is encircled by a shallow ditch, known in the archaeological literature as a fosse. Here, each mound is small and flat-topped, with basal diameters ranging from about 4.9 to 6.2 metres and heights of only 0.1 to 0.2 metres, barely ankle-height above the surrounding ground. The fosse, where it survives, is around a metre wide, and survives as faint traces on all but the most southerly mound in the main group. The spacing between mounds is irregular, varying from as little as two metres to as much as twenty, which gives the line an uneven, organic quality rather than the look of deliberate geometric planning. They were confirmed as visible on a Department of Defence aerial photograph taken in 1999, which is often how such low-profile earthworks come to light, their subtle relief picked out by the raking shadows of oblique photography.

The Curragh itself, a vast open limestone plain that has served as a military training ground and racecourse for centuries, preserves an unusual density of prehistoric remains precisely because sustained tillage agriculture never broke up its thin turf. That relative continuity of land use is almost certainly why mounds this shallow, only ten to twenty centimetres high, have survived at all.
