A cairn of this type is essentially a mound of stones heaped over a burial or as a marker in the landscape, and this one is substantial enough to demand attention even in its overgrown state: nearly two metres high and roughly nineteen metres across in both directions, with a slightly subrectangular rather than perfectly circular footprint, which is itself an uncommon characteristic.

The cairn does not stand alone on the hill. To its north lies a ring-barrow, a low circular earthwork enclosing a central burial area, a form of funerary monument associated broadly with the Bronze Age in Ireland. The pairing of monument types on a single elevated site suggests this hilltop carried some significance across a long span of prehistoric use, with different communities returning to it, or at least acknowledging what was already there. The specific date of either monument has not been established, and without excavation the cairn's contents and precise period remain unknown.
