Roughly thirty metres in diameter, it survives now only as a faint arc of raised ground, no more than twenty centimetres high at its most visible, curving from the south around to the northwest. The rest has been levelled, absorbed into the working landscape of a field that has been grazed and managed for generations. What remains is essentially a rumour in the soil.

The enclosure was clear enough on the Ordnance Survey six-inch map of 1935, where it was marked as a hachured circular raised area, the standard cartographic shorthand for a ringfort or similar earthwork. Ringforts, which were typically used as enclosed farmsteads during the early medieval period in Ireland, are among the most common archaeological monument types in the country, yet individually many have been quietly erased by agriculture, drainage, and development over the past century. At Coolroe, the 1935 map also showed the enclosure sitting within a trapezoidal area of rough grazing, bounded on the south by a field boundary and on the other three sides by a broken line, suggesting the hillock and its surroundings were already set apart from the more intensively worked land around them. By 1979, when an aerial photograph was taken, the circular outline was still legible from the air as a low scarp or rise within what had by then become an overgrown square area, the kind of cropmark or earthwork shadow that rewards a careful eye but defeats a casual glance at ground level.

The site sits in pasture now, and the surviving arc of earthwork is subtle enough that its significance is easy to miss without knowing what to look for. The slight elevation of the hillock itself may be the most immediately noticeable feature, the circular geometry of the old enclosure discernible only where that low rise traces its remaining curve through the grass.
