A cist is essentially a small box grave, formed from flat or edged stones and typically used during the Bronze Age to inter human remains, sometimes accompanied by a ceramic vessel or personal objects. This one measures roughly 1.7 metres east to west and 0.7 metres north to south, dimensions consistent with a single inhumation or cremation deposit, though its contents are not documented in what is currently known about the site.

The feature was identified by Paul Walsh and Tom Coffey, and what makes it quietly remarkable is not just its survival but its immediate context. A second cist sits parallel and directly to the south, within the same central zone of the cairn. Two cists placed so deliberately close together, aligned in the same orientation and apparently contemporary with the same mound, raises questions about whether they represent successive burials within a family or community group, or some more deliberate pairing of the dead. That kind of double-cist arrangement is known elsewhere in Ireland but is far from routine. The cairn they occupy, a mounded heap of stones raised over the burial or burials it was built to mark, would once have been a conspicuous landmark in this part of the Burren fringe landscape.
