The example at Ré Na Ndoirí in County Cork sits at the smaller end of that spectrum, tucked into a boggy, narrow defile between two low ridges of outcropping rock. It is the kind of place that rewards close attention precisely because there is nothing obviously grand about it: thin stone slabs arranged with quiet precision in a damp hollow, the surrounding landscape doing little to announce what is there.

Wedge tombs, so called because the gallery narrows and lowers from one end to the other, are generally dated to the late Neolithic and early Bronze Age, roughly 2500 to 2000 BC, and are found in greatest concentration in the west and south of Ireland. The Ré Na Ndoirí example is modest even by the standards of the type. The gallery runs on an east-north-east to west-south-west alignment and measures roughly 1.25 metres in length, opening to about a metre in width at the western end and narrowing to around 0.6 metres at the eastern end. A single sidestone survives to the north and another to the south, with an inset backstone closing the eastern end. The whole structure is enclosed within closely-set outer walling, all of it composed of thin slabs. The deliberate tapering in both width and height from west to east is characteristic of the type, though the scale here is particularly compact. The site was recorded and described by Seán Ó Nualláin in 1989.
