But the low, stony curve running around it marks the surviving edge of a rath, the Irish term for a ringfort, the kind of enclosed farmstead that once dotted the early medieval landscape in extraordinary numbers. Most were built and occupied roughly between the fifth and twelfth centuries, serving as defended homesteads for farming families rather than as military fortifications in any grand sense. The bank, even in its present reduced state, would once have carried a timber palisade or dense hedge, and the enclosed space inside would have sheltered a dwelling, outbuildings, and livestock.

The rath at Ballygiltenan sits on the south-facing slope of an east-west ridge, a position that would have offered good drainage and reasonable shelter. The enclosure is sub-circular, measuring approximately 14 metres north to south and 19 metres east to west. Its earthen and stone bank has eroded considerably over the centuries, surviving best along the south-west to west and north-west to north sections, where it still reaches an external height of around 0.4 metres. On the south-east to south-west arc, the builders appear to have relied on the natural topography rather than a constructed bank, using the top line of a steep natural incline as the boundary. The interior is scattered with loose stones, most likely material that has gradually slipped from the eroding bank itself. The notes were compiled by Denis Power and uploaded in August 2011.

The site sits in open pasture, so access depends on landowner permission, as is standard with the majority of field monuments in rural Ireland. The northern stretch of the bank, overgrown with gorse, is the most visually distinctive section, though the vegetation makes close inspection awkward. A modern field boundary runs immediately outside the bank on the north side, which can initially make it harder to read the line of the original earthwork. The best way to appreciate the shape of the enclosure is to walk its perimeter slowly, watching how the ground changes underfoot, particularly where the constructed bank gives way to the natural slope on the southern side.
