A ring barrow is a burial mound of the type common across Ireland and Britain from the Bronze Age onward, typically consisting of a raised central platform surrounded by a circular ditch, or fosse, and an outer earthen bank. The example at Heath sat on a broad, low rise above the generally poorly drained terrain around it, which would have given it a degree of prominence in the landscape despite its modest scale.

When inspected in 1982, the ring barrow was still intact. The central platform measured nine metres across in both directions and was enclosed by a waterlogged, rush-grown fosse. Beyond that ran a broad, low external bank roughly four metres wide, bringing the overall diameter of the monument to twenty-three metres from one crest to the other. Notably, the central platform appeared to sit slightly below the surrounding field level, and disturbance to the southern side had made its plan somewhat irregular, suggesting earlier interference. The structure had not been recorded on the 1838 Ordnance Survey six-inch map, though by the 1930 edition a roughly circular hachured area, the cartographic convention used to indicate an earthwork, was marked at the site. Sometime during the later 1980s, land reclamation works levelled the monument entirely. By the time of a follow-up inspection in 2000, the central platform and enclosing fosse could only be traced as slight undulations across the surface of the field, faint impressions where something considerably older had stood.
