The feature measures roughly thirteen metres east to west and at least seven metres north to south, and it came to light only because someone was planning to build a house nearby. Test-trenching ahead of that construction revealed what archaeologists describe as a burnt mound, a class of prehistoric site found widely across Ireland and Britain. Burnt mounds typically represent repeated episodes of heating stones in fire and plunging them into water-filled troughs or pits, most likely for cooking, bathing, or industrial processes. The cracked and fire-shattered stones that result accumulate over time into spreads or horseshoe-shaped heaps, often in low-lying, waterlogged ground where water was reliably available, which fits the marshy setting here precisely.

What gives this particular site an added layer of interest is its relationship with the Claidh Dubh, a substantial linear earthwork that runs for considerable distances across parts of Counties Cork and Kerry. The western edge of the burnt mound terminates directly against a section of this earthwork, placing the two features in close physical proximity, though whether that proximity is coincidental or meaningful is not recorded. The Claidh Dubh itself is a poorly understood monument, its date and purpose still debated, but its scale suggests it was a significant boundary or territorial marker in the early medieval or possibly prehistoric landscape. That a spread of heat-shattered stones should abut it, sitting just beneath the surface of a damp field, gives the location a quietly layered quality. The burnt mound was not disturbed by the house construction that prompted its discovery and remains preserved in place beneath the soil, as found.
