The structure in question was a cromlech, a term once used loosely to describe megalithic monuments, likely a wedge tomb of the kind common across Munster, built from large stone slabs and used for collective burial during the Neolithic or early Bronze Age. Nothing of it remains above ground today.

The story of its disappearance comes from James Grove White, who recorded it sometime between 1905 and 1925. A landowner told him that forty-two paces to the south-west of a surviving wedge tomb in the same field, another structure had stood until around 1877, when it was taken down. The landowner recalled that it measured roughly eight feet square, that its stones were brittle and showed signs of burning, and that the earth around it was noticeably black with what appeared to be charcoal remains. That blackened soil and the burnt condition of the stones hint at fire, whether ritual, accidental, or connected with the clearance of the monument itself is impossible to say. The burning may equally reflect ancient activity associated with funerary practice, since cremated remains are frequently found within wedge tombs.

What makes this site quietly melancholy is not simply the destruction of the monument but how close it came to being recorded at all. The surviving wedge tomb nearby drew the attention that allowed the lost one to be mentioned almost in passing, a footnote to a footnote. The field once held two prehistoric structures; now it holds one, and that one only because it happened to remain standing long enough for someone to ask questions.
