Somewhere in a tilled field in County Kildare, the outline of an early medieval farmstead survives in the soil, its original ditch now carrying plastic land-drainage pipes. The ringfort, a roughly circular enclosure of the kind that once served as a defended homestead for a farming family, sits at the eastern foot of a low ridge, about five hundred metres northeast of Rathcoffey Castle. It is the sort of monument that aerial photography tends to catch more clearly than a walk across the ground would suggest.

The enclosure is sub-circular in plan, measuring just over thirty-two metres north to south and nearly twenty-nine metres east to west across the interior. It is defined by a low earthen bank, standing between one and two metres above the outer ground surface where it is best preserved along its northern and eastern arc, though elsewhere this has been reduced to little more than a scarp. Beyond the bank runs an outer fosse, a shallow ditch roughly eighty centimetres wide and up to a metre deep, which has been absorbed into the modern agricultural drainage system, with plastic pipes now visible in the eastern and western sectors. The interior rises slightly above the surrounding ground level, though it slopes gently downward from west to east. The eastern portion shows signs of disturbance, with decaying tree stumps, while thorn and scrub has begun to colonise the western side. The monument was confirmed as visible in tillage on an aerial photograph taken in 2005.
