It measures roughly twenty metres across and rises to about one and a half metres in height, which makes it a substantial example of its type. What gives it an extra layer of strangeness is that it does not stand alone: two further monuments of the same kind lie within about a hundred and ten metres to the west, as if the same wet, low-lying ground attracted repeated activity across generations.

A fulacht fia, sometimes also written fulacht fiadh, is a type of prehistoric cooking site found in great numbers across Ireland. The characteristic mound is composed of fire-cracked stones, the accumulated debris of a process in which rocks were heated and dropped into a water-filled trough to bring it to the boil. This example at Dromore carries an additional complication in its archaeology. The mound is ringed by a low bank and an external waterlogged fosse, a shallow ditch, and the arrangement is unusual enough that it may not be prehistoric in origin at all. When the site appeared on the Ordnance Survey six-inch map of 1842, it was recorded as a circular enclosure planted with trees within the demesne of Dromore House, and the bank and fosse could plausibly be the result of that Victorian-era landscaping rather than any ancient intent. A reference by Bowman in 1934 to a fulacht fiadh on the land of a J. Long, described as twenty yards in diameter, may refer to this same mound, which would place it within living agricultural memory at that point, still recognisable even if its original purpose had long been forgotten.
