What gives it away is the geometry: a near-complete subcircular circuit, some 41.5 metres north to south and 35 metres east to west, with a clearly intentional entrance gap of 2.5 metres opening to the south-east. An outer fosse, the term for a defensive or enclosing ditch dug to accompany an earthen bank, runs along the eastern, western, and northern sides, though it has long since been pressed into service as an agricultural field drain. The bank itself, overgrown now, still stands noticeably higher on its outer face than its inner, reaching 2.2 metres externally against 1 to 1.2 metres on the interior side.

Enclosures of this type are among the more ambiguous features in the Irish archaeological landscape. They could represent the remains of a ringfort, a form of enclosed farmstead common in early medieval Ireland, or something earlier or later again. The morphology here, a bank with an external fosse and a formal entrance, follows a pattern seen across the country, though without excavation the date and function of this particular example remain open questions. What is certain is that by 1988 the interior had been planted with coniferous trees, a decision that will have altered ground conditions inside the enclosure and made surface survey of the interior considerably more difficult. A stream runs roughly east to west about 60 metres to the south, which would have made the slight natural rise on which the enclosure sits a sensible location for a settled or enclosed space, positioned just clear of the wetter ground below.
