Roughly 25 metres across in both directions, it is defined by a substantial earthen bank along its north-west to eastern arc, with a slighter, less pronounced feature completing the circuit elsewhere. The interior is not empty but covered in north-to-south cultivation ridges, the kind of parallel earthen strips left by generations of hand or horse tillage. Whatever agricultural life once played out inside this enclosure, it left its marks clearly enough to read from the air.

Enclosures of this general type, roughly circular earthworks bounded by a bank and sometimes a ditch, are common across the Irish landscape and were put to many uses over many centuries, from early medieval settlement to later farmyard enclosures. What makes this one quietly notable is that it was never recorded on any mapping. It was first brought to wider attention by Jean Charles Caillère, who identified it through aerial and satellite imagery, where it shows clearly on MapGenie images dating to 1995 as well as on Google Earth and Apple Maps. A small canalised stream running south-west to north-east lies about 80 metres to the south-east, and that same watercourse marks the county boundary with Meath, placing this unrecorded earthwork right at the edge of two counties.
