The one in question is a wedge tomb, the most numerous class of megalithic tomb in Ireland, typically dating to the late Neolithic or early Bronze Age and named for the characteristic tapering of the chamber from a wider, taller entrance end down to a narrower back. This example measures about 2.5 metres in length and 1.3 metres in width, modest even by the standards of the type.

The chamber is oriented on a northwest to southeast axis, a broadly typical alignment for wedge tombs, and is constructed from a backstone at the eastern end, a single sidestone along the north, two sidestones along the south, and a notably high septal-stone closing the western end. A septal-stone is a slab set across the interior to divide or seal the chamber, and here it forms the most prominent upright remaining. The interior is currently filled with field stones, the accumulated clearance of generations of farming on the surrounding pastureland. That pastureland runs level to the south of a small stream, a quietly unremarkable setting that gives no obvious indication it was once considered a significant enough place to bury the dead twice over, with the companion tomb standing not far to the northeast.
