It measures roughly nine metres north to south and four metres east to west, rising to about half a metre above the surrounding ground, and it is made almost entirely of heat-shattered stones mixed with charcoal-enriched soil. That particular combination is the calling card of a fulacht fia, a type of prehistoric cooking site found in considerable numbers across Ireland, typically Bronze Age in date. The standard interpretation is that stones were heated in a fire, then dropped into a water-filled trough to bring it to the boil, a process repeated until whatever was being cooked, most likely meat, was done. The discarded, cracked stones accumulated over time into the distinctive horseshoe or kidney-shaped mound that archaeologists recognise today.

This example sits immediately south of an earthen field boundary enclosing an area of scrub, a landscape detail that hints at how quietly these sites persist within the working countryside, absorbed into the edges of fields and forgotten in practical terms even as they survive physically. Local knowledge recorded alongside the site mentions a well to the north-east of the mound. That proximity is unlikely to be coincidental. Fulachtaí fia are almost always found near a reliable water source, whether a stream, a spring, or a well, since the entire cooking process depended on a ready supply. The well at Lackanalooha, if it represents an ancient source rather than a later addition, would fit that pattern precisely.
