That measured uncertainty is itself revealing. After perhaps four thousand years, this monument still resists a clean reading.

Wedge tombs are the most numerous megalithic tomb type in Ireland, built roughly between 2500 and 2000 BC, and they take their name from the characteristic tapering of both height and width from front to back. The example at Curreeny Commons follows that pattern: a double-walled gallery at least seven metres long, narrowing to a maximum width of 1.2 metres, with the gallery sides decreasing in height towards the east. A septal-stone, a single upright slab set across the interior to divide the space, separates a portico at the west-south-west end from a main chamber some five metres in length. The south side of that chamber is defined by five orthostats, the upright standing stones that form the structural skeleton of the gallery, with a prostrate stone beside the easternmost that may once have stood alongside them. The north side runs to six orthostats in an irregular line, and almost a metre beyond the last of these stands one further stone whose role remains ambiguous: buttress, backstone support, or the remnant of a wall continuing further than now survives. The doubled walling, a second skin of stones running alongside the main orthostats, is represented by multiple stones on both sides, though interpreting exactly what each one originally did requires the kind of careful on-site reasoning documented by Ruaidhrí de Valera and Seán Ó Nualláin in their 1982 survey of the megalithic tombs of Munster.
