Drainage works have carved through the surrounding ground, and most of the mound itself has been dug away over the years. What survives is a single quadrant, the north-east to south-east portion, measuring roughly four metres north to south and standing only half a metre high. A mature ash tree has taken root on top of it, its roots now threading through whatever remains beneath.

The mound is recorded alongside a possible cist, a type of small stone-lined burial box typically associated with prehistoric interment, suggesting the site may once have had a funerary function. Mounds of this kind are scattered across Ireland, often raised over burials dating from the Bronze Age, though without excavation it is difficult to say with certainty what this particular example contained or when it was constructed. The site was brought to wider attention by Dr C. Cunniffe, and the surviving fragment, modest as it is, represents what has escaped the digging and drainage activity that removed the rest. Clonfert itself is a place with a long ecclesiastical history, and the presence of prehistoric features within its demesne is a reminder that the ground was significant long before any monastery was founded there.
