When the Ordnance Survey recorded this area for their 1914 six-inch edition, the feature appeared only as a small circular mark, its diameter estimated at around twenty metres. The reality, when measured properly, is somewhat larger: roughly twenty-seven metres across. That discrepancy is a small reminder of how much early cartographic notation compressed or simplified what was actually there.

A ringfort, sometimes called a rath, is an enclosed farmstead of early medieval date, typically defined by one or more earthen banks and ditches surrounding a circular living area. This example sits at the western edge of a low shelf of ground, with the River Shannon running roughly east to west about a hundred metres to the north. The enclosure is defined by a slight bank on both the northern and southern sides, nowhere rising more than about 0.7 metres above the external ground level, and a fosse, or ditch, survives in traces around the south-eastern to south-south-western arc. A scarp, a natural or cut slope rather than a built-up bank, defines the circuit elsewhere. The probable entrance, at the south-east, is just under two metres wide at its base. It is modest in scale and modest in survival, but the basic geometry of the place, the deliberate shaping of ground to enclose a domestic space, is still legible. The site is now absorbed into a planted coniferous forest, which both preserves and obscures it; the trees have protected the earthworks from agricultural disturbance while making any casual inspection a matter of pushing through dense shade and fallen timber.
