In the upper Araglin river valley in County Waterford, a large stone box sits at the centre of a cairn on a gentle west-facing slope, its interior still partially visible despite centuries of collapse and slip. This is a cist, a type of prehistoric stone-lined burial chamber, typically formed by setting upright slabs on edge to create a box in which the dead were interred. This particular example is notably substantial, measuring at least 1.6 metres by 1.6 metres across, with the eastern and western sides formed by single large stones standing a minimum of 0.9 metres high. The remaining sides are obscured beneath the slumped material of the surrounding cairn, a mound of stones heaped over the burial, which has gradually spread and settled over the millennia.

What makes the site quietly unusual is that it does not stand alone. Roughly 60 metres to the south, on the far side of a small east-west stream, there is a second burial cairn. The two monuments sit on opposite banks of the water, oriented along a northeast-southwest valley carved by the upper Araglin river. The pairing of burial monuments across a natural boundary like a stream is not a common arrangement, and the deliberateness of the placement is hard to dismiss. The site forms part of a wider national monument complex at Coumaraglinmountain, afforded protected status under a preservation order in 1996, which points to the concentration of prehistoric remains in this upland area of the Waterford and Cork borderlands. Michael Moore, who documented the site in detail in 1995, recorded the complex within a broader survey of the region's archaeological landscape.
