First recorded on Ordnance Survey maps between 1848 and 1851, this earthwork was initially described by Thomas Fagan as a grave enclosed by large flagstones, some of which had fallen onto the burial site itself. By Fagan’s time, these original stones had been obscured by a cairn of smaller stones that had been gathered more recently, suggesting the site had been modified over the years.

The feature’s appearance changed considerably over time, or perhaps different observers simply saw it differently. Whilst the earliest accounts mention the presence of stones, by 1903 the Ordnance Survey Name Book made no reference to any stone elements at all, describing it instead as a simple low mound of earth. Local tradition held that it was an oval mound, roughly six metres long, three metres wide, and about half a metre high. The site even had its own legend attached to it, recorded in the 1848;51 revision notes, though the specific details of this story have been lost to time.

The mound met its end around 1940 when it was destroyed, revealing a rather anticlimactic discovery; the entire structure was composed solely of clay, with no internal chambers or megalithic architecture. This finding effectively ruled out any possibility that it had been a megalithic tomb, despite decades of speculation. Today, no trace remains of this enigmatic feature that once drew the attention of antiquarians and inspired local folklore. Its true purpose, whether it was indeed a burial mound or served some other function in the landscape, remains one of Donegal’s minor archaeological mysteries.
