They are gone now, ploughed out of existence sometime after the mid-1970s, and the land shows no apparent trace of them. What makes the loss particularly pointed is that these were not obscure or ambiguous features: locals could describe them clearly as horseshoe-shaped mounds made up of burnt stone, the unmistakeable signature of a fulacht fia.

A fulacht fia is a type of ancient outdoor cooking site found in enormous numbers across Ireland, typically dated to the Bronze Age. The standard interpretation is that stones were heated in a fire and then dropped into a water-filled trough to bring it to a boil, with the cracked and fire-shattered stones accumulating into the characteristic mound around the trough's edge. The horseshoe or crescent shape described by people at Killoughane fits this pattern precisely. What does not fit any tidy pattern is the object found when one of the mounds was levelled: a metal item described as boat-shaped. No further detail about it has been recorded, and its current whereabouts are unknown. Whether it was a vessel of some kind, a tool, or something else entirely, it had presumably been deposited at or near the site at some point, and the chance to examine it properly seems to have been lost along with the mounds themselves.
