The coincidence is easy to miss, because the fort itself is largely gone, absorbed back into the pasture that surrounds it on all sides.

The 1837 edition of the Ordnance Survey six-inch map recorded the site clearly, marking a circular enclosure of roughly 43 metres in diameter and labelling it simply "Fort". Earthen ringforts of this kind were typically used as enclosed farmsteads during the early medieval period in Ireland, the circular bank providing a boundary for a household and its livestock rather than a military fortification in the conventional sense. By the time the late nineteenth or early twentieth century farmhouse was constructed within its southern sector, the monument had already been substantially levelled. What remains now is fragmentary: a low bank of earth and stone, around 1.5 metres wide, survives at the northern and eastern edges, standing no more than 0.4 metres above the external ground surface and a modest 0.2 metres above the interior. It is the kind of earthwork that would register as little more than a gentle ripple underfoot. The site sits on a low rise with open views in all directions, which is itself a clue to its origins; early medieval enclosures were routinely placed on slightly elevated, well-drained ground, combining practicality with a degree of visibility across the surrounding landscape. What makes Ballyrevagh quietly odd is the layering of it: a prehistoric or early medieval boundary, recorded by Victorian cartographers, later interrupted by a farmhouse that has since become the dominant feature of the place the fort once defined.
