Whoever built this enclosure on the lower slopes of the Blackstairs Mountains left no obvious way in, or at least none that has survived. Only the western portion of the site remains, giving it a D-shape rather than the circular form these earthworks typically take, and the surviving half is now grass and scrub rather than the managed farmland it once enclosed or protected.

Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, built roughly between the fifth and twelfth centuries. They consisted of a circular bank of earth enclosing a domestic area, usually accompanied by a fosse, the external ditch from which the bank material was dug. At Boladurragh, the proportions are still readable in the landscape: the earthen bank runs between 4.8 and 5.4 metres wide, standing about 0.6 to 0.8 metres above the interior and considerably more on the outside, where the external face rises 1.6 to 1.8 metres. Beyond that bank sits a fosse roughly five metres across at the top and 1.6 metres deep, and beyond that again an outer field wall running roughly south-southeast to north-northwest. The combination of bank, fosse, and outer wall would have made for a layered, deliberate boundary, the kind of arrangement that suggests both agricultural order and a concern for defined territory, if not outright defence.

The site sits towards the bottom of a south-facing slope in the Blackstairs foothills, a landscape that still feels peripheral and quiet, at some remove from the busier lowlands of County Wexford. The eastern half of the ringfort has been lost entirely, leaving this surviving arc as the only indication of what was once a complete enclosure. The absence of any traceable entrance makes it harder to read the site as it was originally used, though entrances in earthwork sites can close over centuries of weathering and ploughing. What remains is enough to trace the logic of the place, a curved bank and ditch holding their position on the slope, still legible after more than a thousand years.
