One of those numbers, however, now marks nothing but earth. This particular monument, recorded on the Ordnance Survey's six-inch map of 1838 as a circle of stones, had already vanished from later editions of the same map, erased not by time alone but by deliberate clearance.

The antiquarian George Petrie noted it in 1837, placing it in a small field to the east of another monument in the complex. His account is brief but telling: only a few stones of the circle remained at the time of his visit, and he recorded that it had been destroyed roughly twenty years earlier, around the turn of the nineteenth century, by the tenants of a Mr Walsh. During that destruction, human bones were found within what Petrie called the tomb, suggesting this was a megalithic passage tomb or related funerary structure, a type common across Carrowmore, typically consisting of a central chamber surrounded by a kerb of boulders. The bones would have been the remains of the Neolithic dead, interred perhaps five thousand years ago. Within a generation of Petrie writing that sentence, the monument was gone entirely. Today there are no remains visible at ground level.
