The structure is small, roughly circular, and built from drystone, that is, stone laid without mortar, relying on careful stacking alone to hold its shape. Its eastern side has not survived, but enough remains to measure the interior at roughly 6.8 metres by 6.3 metres, with walls still standing to about 0.9 metres in height and 1.3 metres in thickness. What it once sheltered, and who built it, is not recorded.

What makes the site quietly puzzling is its contested identity. The Ordnance Survey Name Books, compiled in the nineteenth century as part of Ireland's first systematic mapping effort, recorded the feature under the townland name Drummod and classified it as an earthen fort. That designation carries significant weight in the Irish landscape; earthen forts, or raths, were typically enclosed farmsteads of the early medieval period, surrounded by a bank and ditch. But a closer look at this structure finds no evidence of an outer enclosure, which is usually the defining characteristic of a rath. The circular drystone foundations read more plausibly as a simple hut, perhaps used for seasonal grazing or shelter on the mountain rather than as a permanent defended settlement. The gap between what earlier surveyors assumed and what the physical remains actually show is itself a small lesson in how landscape features get misclassified when examined quickly or from a distance.
