This one, in the townland of Shanaclogh, is modest in most respects but quietly complicated in its construction, as though whoever built it adapted the standard plan to suit the particular demands of the ground beneath them.

The enclosure is roughly circular, measuring just under thirty metres across in each direction, and sits on a gentle south-east-facing slope in what is now pasture. To the south and south-east, the builders followed the conventional approach: two earthen banks separated by a fosse, that is, a ditch dug to reinforce the barrier, with a further external fosse about a metre deep beyond that. But moving around to the west and north, the arrangement changes. The intervening fosse and outer bank are replaced by a berm, a flat shelf of ground roughly five metres wide, which offers separation without the full double-bank-and-ditch treatment. To the north-east, both banks are consolidated into a single large earthen bank standing 2.6 metres high, a considerable mass of earth for what might otherwise seem a modest site. Large boulders have been dumped into the outer fosse on the western and northern sides, possibly to shore it up or perhaps deposited during later agricultural clearance. Running through the interior, cultivation ridges on a north-north-west to south-south-east axis suggest the enclosed space was worked as tillage ground at some point, a common secondary use of ringfort interiors long after they ceased to function as defended homesteads.

What makes this site worth pausing over is the way its defences vary so deliberately around the circuit. The asymmetry is not neglect or erosion. The south-east-facing slope and the changing terrain likely drove decisions about where to pile earth high and where a berm would suffice, producing a structure that reads, up close, more like a piece of practical problem-solving than a formulaic fortification.
