The cairn is oval in plan, measuring eleven metres north to south and eight metres east to west, and rises to about one and a half metres in height. Modest by any measure, it is the kind of feature that could be walked past without a second glance, yet its presence beside a complex of early settlement remains gives it a quiet archaeological weight.

The cairn belongs to a cluster of features recorded in the townland of Liscunneendeen, known in Irish as Lios Coinín Doinn. The dominant feature of the complex is a univallate rath, meaning a roughly circular enclosure defined by a single earthen bank and ditch, which would once have served as a farmstead or defended homestead in the early medieval period. Within the rath, a souterrain and a hut site have also been recorded. A souterrain is an underground stone-lined passage, typically associated with Irish raths of the early medieval period and thought to have served for storage or as a place of refuge. The cairn itself, sitting fifty metres to the north-east, is composed of a mixture of earth and stone, and was documented as part of the broader archaeological survey of the Corca Dhuibhne region of the Dingle Peninsula, published by J. Cuppage in 1986. The area as a whole is one of the most densely layered archaeological landscapes in Ireland, where field monuments of several different periods frequently occur in close proximity.
