A ringfort, or rath, was a circular enclosed farmstead, typically defined by one or more earthen banks and ditches, and widely used across Ireland from roughly the early centuries AD into the early medieval period. This one was oval rather than perfectly circular, measuring around 50 metres east to west and 65 metres north to south, and it sat on high ground with open views in every direction, which was very much the point. That commanding position was a deliberate choice, whether for defence, status, or the practical advantage of being able to see trouble coming.

Ordnance Survey maps from 1842, 1903, and 1938 all show the enclosure, with later editions also marking the external fosse, the ditch that ran around the outside of the bank. By the time the Office of Public Works visited in October 1967, ahead of Land Project Works in the area, the structure was already levelled, but the earthworks were still measurable: an internal bank some six feet high, with a fosse seven feet deep and twelve feet wide at its base. Hartnett, writing in 1939, noted that it had originally been double ramparted, meaning a second outer bank once encircled the whole site. By his time, that outer bank had already been replaced by modern fencing along the eastern and western sides. Today, what remains is largely a concentration of stone scattered across the area where the fort once stood.
