It is neither. This modest mound, roughly seven metres by six, is a fulacht fiadh, a type of prehistoric cooking site found in considerable numbers across Ireland. The name, loosely translated as "deer roast" or "wild cooking place", refers to a class of monument typically associated with Bronze Age activity, where stones were heated in a fire and then dropped into a water-filled trough to bring it to the boil. Over repeated use, the heat-shattered stones were raked out and piled up, gradually building the characteristic horseshoe or kidney-shaped mound that archaeologists now recognise across the Irish landscape.

This particular example at Tylagh sits thirty metres south of a larger, separately recorded fulacht fiadh site, which suggests the two were perhaps used in proximity to one another, though whether simultaneously or in different periods is impossible to say without excavation. What sets this mound apart from the more typical examples is the apparent absence of a trough area, the sunken or raised feature where water was held and heated. Whether the trough was never built in a form that survived, was obscured by later activity, or lies just below current ground level is unclear. The site was documented as part of Michael Connolly's doctoral research on prehistoric settlement in the Lee Valley, Tralee, completed at University College Cork in 2008, which examined this part of Kerry through a landscape perspective, situating individual monuments within their broader prehistoric environment. Field clearance in the area has affected the mound, which likely accounts for some loss of definition.
