That quiet absorption is itself part of the interest. The enclosure measures roughly 43 metres north to south and 41 metres east to west, making it a substantial example of a rath, the Irish term for a ringfort, which was the most common form of rural settlement in early medieval Ireland, typically used as a defended farmstead between around 500 and 1000 AD.

The earthwork's boundary changes character as it traces its circuit. Along the northern to southern arc, the enclosure is defined by a scarp, essentially a cut or drop in the ground level, rising about half a metre. Moving southward and round to the south-southwest, this gives way to a low earth and stone bank, which then builds into a more substantial bank running from the south-southwest back around to the north, with an internal height of 0.6 metres and an external height of one metre. The interior is slightly elevated and slopes gently downward toward the east, the direction the slope itself faces. That combination, a raised interior and an east-facing gradient, is consistent with the kind of careful site selection that characterised early medieval settlement, where drainage and outlook both mattered. The fact that sections of the bank have been incorporated into the field fence system means the ringfort has not been erased so much as quietly put to work, its ancient boundaries still doing a version of their original job.
