What looks from a distance like a slight rise in the earth is, on closer inspection, a ring-barrow, a type of low circular burial mound ringed by a ditch, known as a fosse, and once enclosed by an outer bank. The site is not one monument but five, a complex comprising two earthworks classed as Type A structures and three ring-barrows, all sharing the same unremarkable-looking ground.

The larger of the two Type A earthworks was recorded in detail by O'Kelly in 1942 to 1943. His description captures something of the monument's subdued scale: a low circular platform rising no more than three feet, roughly 0.9 metres, above field level, surrounded by its fosse, with the outer bank surviving along roughly one-third of its eastern arc. The original overall diameter was approximately 200 feet, or around 61 metres, making it a substantial structure despite the modesty of its current profile. Ring-barrows of this kind are associated with Bronze Age funerary practice across Ireland, and the clustering of several such monuments in one location suggests this was a place of some ceremonial significance over a long period. The earthwork complex at Cloghaviller fits into a wider pattern of prehistoric communities returning to the same landscapes to bury, mark, and perhaps memorialise their dead.

The outlines of the monument remain visible in aerial photography, including on Digital Globe imagery, where the circular cropmarks of the fosse and platform can be traced more clearly than from ground level. Visiting the site itself requires some patience; low earthworks like these are easily missed in longer grass or in poor light, and the remaining bank on the eastern side is the detail most worth seeking out. Early morning or late afternoon light, when shadows are longer and the ground texture more pronounced, gives the best chance of reading the topography with any clarity. As with many such sites in the Irish midlands and west, the landscape offers few dramatic visual cues, which makes the moment of recognition, when the circular form finally resolves itself underfoot, all the more satisfying.
