There is no obvious way in, at least not one that survives above ground, and that absence is part of what makes the site quietly arresting. What remains is a near-perfect circle of grass and rushes, roughly 27 metres across, still holding its shape after more than a thousand years.

The structure is a rath, the Irish term for a ringfort, a type of enclosed farmstead typically built during the early medieval period, between roughly the fifth and twelfth centuries. Most were the homes of farming families, their earthen banks serving less as military fortifications and more as a practical boundary against livestock and a marker of status. Here, the enclosure is defined by an earthen bank around 4.5 metres wide, which stands just 0.2 metres above the interior ground level but nearly a metre above the exterior, giving it a more pronounced outward face than inward one. Beyond the bank lies a fosse, the term for a surrounding ditch, now 2 to 3.5 metres wide at its base and identifiable today mainly by the band of rushes that traces its circuit, rushes being a reliable indicator of waterlogged or disturbed ground. Bushes have taken hold along the south-south-west to west-north-west arc, while a low scarp of 0.3 to 0.5 metres marks the line elsewhere. The ridge setting is typical; builders of raths generally favoured slightly elevated ground for drainage and visibility, even when the rise was modest.
