But this structure at Maumnahaltora is something more precise: it is the westernmost of a cluster of wedge tombs, a type of megalithic burial monument built during the later Neolithic and into the Bronze Age, typically consisting of a long, tapering stone gallery that narrows and lowers from one end to the other. This particular example sits roughly 45 metres west of its nearest neighbour and about 100 metres south-west of a third tomb in the group, making it the outermost of the three.

The construction is careful and considered in ways that become apparent only on close inspection. The gallery runs approximately three metres in length, or up to 3.75 metres if measured from the probable septal-stone, a low threshold or dividing slab set across the western entrance. The sides are each formed of two stones, with the tall, well-matched western pair set slightly proud of the inner sidestones, their tops sloping downward from west to east. This deliberate drop in height is characteristic of wedge tombs generally, with the gallery widest and tallest at its open end, here to the west, and tightest at the enclosed eastern end, where a single backstone closes the chamber and a solitary roofstone covers it. An additional slab just outside the eastern wall on the northern side suggests a doubling of the gallery wall at that point, a detail noted by J. Cuppage in the Dingle Peninsula archaeological survey published in 1986, and also examined by Ruaidhrí de Valera and Seán Ó Nualláin in their 1982 survey of megalithic tombs across Munster. Traces of a surrounding mound survive to the west and north of the structure, though a field drain has disturbed the original outline at the western end.

The tomb carries a preservation order under the National Monuments Acts, which gives some indication of how seriously it is regarded despite its relatively modest scale. Visitors exploring the Dingle Peninsula who know to look beyond the better-publicised monuments of Corca Dhuibhne will find in this small, quietly asymmetrical structure a good deal to read in the stonework itself.
