Sitting on top of this slight rise is a rath, the Irish term for a ringfort, an enclosed farmstead of the early medieval period, roughly between the fifth and twelfth centuries. Thousands of these survive across Ireland, but this one is in unusually good condition, with its earthworks reading clearly in the landscape.

The enclosure is roughly circular, measuring forty metres north to south and forty-two metres east to west, which gives a sense of the modest but workable space once contained within. The main earthen bank still stands up to 3.4 metres high on its outer face, a considerable presence for a structure built without mortar or dressed stone. Around the outside of that bank runs a fosse, essentially a defensive ditch, cut to a depth of 1.6 metres, and beyond that a counterscarp bank, a secondary raised edge to the ditch, which survives to 1.2 metres along the south-southeast to west-southwest arc. That counterscarp continues northward as low foundations, now carrying a stone field fence, which means later farmers quietly incorporated ancient infrastructure into their own boundaries. On the interior face, towards the northeast and east, the bank is stone-faced, suggesting some effort at consolidation or reinforcement. The original entrance faces east, four metres wide and approached by a causeway crossing the fosse, a sensible arrangement that kept livestock in and unwanted visitors at a slight disadvantage. A later cattle gap cut into the west-southwest side reflects the site's continued agricultural use into modern times.

The fort sits in open pasture and the hillock setting would have given its early medieval occupants a clear view across the surrounding ground, which was probably the point. The earthworks are substantial enough to be read without any specialist knowledge; the circuit of bank, ditch, and counterscarp is still largely intact, and the original eastern causeway entrance is visible as a distinct break in the profile.
