Known locally as Brennan's Fort, this ringfort, a type of enclosed farmstead typically defined by one or more circular earthen banks and ditches, common across Ireland from the early medieval period, now leaves no visible surface trace for anyone walking across the field where it once stood.

The site was recorded on the first edition of the Ordnance Survey six-inch map as a circular enclosure roughly thirty metres in diameter. Writing in 1914, a researcher named Neary catalogued it as a circular, earthen ravelled fort, that term referring to an earthwork whose banks have eroded or spread outward over time, losing their original sharp profile. Even by that point, the structure was presumably in a degraded state. Whatever remained since has been lost entirely, most likely to agricultural levelling. The survival of a local name, Brennan's Fort, suggests the enclosure remained a recognised landmark in living memory for generations before it disappeared, even if no one alive today can point to its outline. A second ringfort survives approximately one hundred metres to the north-west, offering a faint sense of what this landscape once held in terms of early settlement activity.
