What was once a substantial structure, standing some 2.5 metres high and aligned north to south, is now so obscured by modern agricultural clearance that only a single upright stone remains visible above the accumulated spoil. The informal name, Druids Altar, follows a long tradition of attaching druidic associations to ancient megalithic monuments across Ireland, though the structure predates the druids by several millennia and the label tells us more about nineteenth-century romanticism than about the monument itself.

Archaeologists have struggled to classify it with confidence. The surviving evidence suggests connections to either the court tomb or portal tomb traditions, both of which are Neolithic burial forms, generally dating to around 4000 to 3500 BC, typically consisting of a roofed stone gallery used for collective burial, sometimes fronted by an open ceremonial forecourt. A photograph held in the Bord Fáile archives offers a glimpse of what the structure looked like before further deterioration set in, showing a stone at the northern end of the gallery and a gable-shaped backstone closing its southern end. Researchers Prendergast and O'Kelly both noted the monument in the late 1960s, and their references remain among the few published records of its existence.

The tomb sits roughly 100 metres west of the River Barrow, tucked against the base of a slope that would have offered shelter and perhaps deliberate orientation to whoever raised it. The accumulation of field debris means that much of what might once have clarified its type and extent is now buried under the very landscape it has occupied for thousands of years, making it an elusive and somewhat melancholy site for anyone who does make their way out to find it.
