What makes it worth a second look is precisely how thoroughly the modern field system has swallowed it. Dry-stone walls run along the top of its earthen bank on one side, and a separate linear field wall clips the bank on another. The ringfort has not been preserved so much as pressed into service, its boundaries repurposed by farmers who may or may not have given much thought to what they were building on.

A rath, as this type of site is classified, is a ringfort defined by an earthen bank and ditch, the most common form of early medieval farmstead in Ireland, typically dating from roughly the fifth to the twelfth century. They served as enclosed homesteads for farming families, the bank offering a degree of protection for livestock as much as people. The Graigues example is modest in scale, measuring approximately 26.7 metres north to south and 26 metres east to west, with an interior earthen bank standing around 0.7 metres high on the inside and a shallower 0.35 metres on the exterior. The notes compiled by Denis Power record that the bank is best preserved along its north-western to east-north-eastern arc, which is also the stretch where the field wall has been laid directly on top of it, running south-eastward from there. A separate field wall clips the bank on the west-south-western to north-western side, suggesting the enclosure has been intersected by the field system from more than one direction over the centuries.

The site sits on a break in a north-facing slope, which means the interior, described as level and under rough pasture, would have offered a reasonably sheltered platform. Visitors approaching across open farmland should be prepared for uneven ground and the usual practicalities of accessing a working agricultural landscape; permission from the landowner is both courteous and necessary. The most legible portion of the bank is the north-western arc, where the profile is clearest before the dry-stone wall takes over. Looking carefully at the junction between old earthwork and later stonework is where the site becomes genuinely interesting, a small, unremarked collision between two very different eras of land management.
