These are conjoined ring-barrows, a type of funerary enclosure typical of the Bronze Age in Ireland, where the dead were interred within a circular area defined by a surrounding ditch, known as a fosse, and an outer earthen bank. What makes the pair at Farneigh quietly remarkable is the conjunction itself: two distinct monuments, each with its own dimensions and orientation, meeting at the south where the larger gives way to the smaller.

The larger of the two measures roughly 16.5 metres across in the northwest to southeast direction. Its fosse is approximately 2.2 metres wide, and the outer bank, at about 1.7 metres wide with an external height of 1.2 metres, is most clearly defined at the south, precisely at the point where the second barrow adjoins it. That second enclosure is somewhat smaller, measuring 13.6 metres north to south, with a fosse of the same width as its companion and an outer bank that includes a causewayed entrance on the east side, a gap left deliberately to allow access to the interior. The site does not stand alone in the landscape; a ringfort lies to the northwest, and three further ring-barrows are scattered to the west, north, and southeast, suggesting this hilltop held some sustained ceremonial or funerary significance over a long period.

The interiors of both enclosures and their banks have been planted with conifers, which means the earthworks, though measurable and structurally legible, are now growing through a dense tree cover that complicates any clear reading of the ground from a distance.
