What makes this particular monument quietly arresting is the precision still visible in its layout: not simply a heap of earth raised over the dead, but a carefully engineered structure with distinct components, an entrance, and upright stones that continue to stand in place after what is likely several thousand years.

The monument is a bowl-barrow, a form of prehistoric funerary mound typically associated with the Bronze Age. The type takes its name from its cross-sectional shape, in which a central mound is enclosed by a surrounding ditch and, in some cases, an external bank, producing something resembling an inverted bowl viewed from the side. At Carrowkeel, all of these elements survive in measurable form. The central mound is roughly circular, about 11.5 metres across, and flat-topped, edged by a scarp between 0.65 and 1.2 metres high. Outside that sits a fosse, the encircling ditch, which varies in width from 1.4 to 4 metres. Beyond the fosse runs an external bank, flat-topped and low. At the north-north-east, stone-facing slabs are still visible along the mound's edge. More striking still is the entrance at the west-south-west: a gap just over 2.5 metres wide, flanked by two upright stones and reached by a causeway crossing the fosse. The larger of the two uprights, on the southern side, measures roughly half a metre across. The monument was recorded on Ordnance Survey six-inch maps in both 1840 and 1916, marked with hachures indicating an earthwork, which means it has been a recognised feature of this landscape for at least two centuries of cartographic record, though its origins are far older.
