It measures roughly eighteen metres along its longer axis and just under a metre in height, its originally rectangular shape now heavily eroded. A cattle track cuts across its north-western tip, and a field fence bisects its south-eastern end. The mound is what archaeologists call a fulacht fia, a type of site found in enormous numbers across Ireland, typically dating to the Bronze Age. The name is sometimes translated as "deer roast" or associated with cooking in the open air, though the exact function of these sites has been debated; the most widely accepted explanation is that they served as outdoor cooking places, where water in a trough was heated by dropping fire-cracked stones into it. Those burnt and shattered stones, discarded after use, accumulated over time into the horseshoe-shaped or rectangular mounds that survive today.

What makes the Killeenemer example particularly worth noting is that it does not stand alone. It is one of a cluster of three such monuments in the immediate area, the others recorded nearby under separate catalogue numbers. This grouping is itself a recognisable pattern; fulachta fiadh are often found in proximity to one another, typically near water sources, which would have been essential for their operation. The stream running just to the north of this mound fits that pattern precisely. The site was recorded as part of the Archaeological Inventory of County Cork, Volume 4, covering North Cork, published in 2000, though the mound's condition suggests it has been subject to gradual disturbance for some time, whether from agricultural activity, livestock movement, or simple weathering over the centuries.
