From the air, the shape is unmistakable: a roughly circular enclosure, its perimeter defined not by a wall or a fence but by a scarp, a slight but deliberate drop in the ground, and beyond that a fosse, the old term for a ditch dug to reinforce or defend a boundary. It is the kind of feature that reads more clearly from above than on foot, and that is precisely what makes it easy to overlook at ground level.

The earthwork first appears in the cartographic record on the 1840 edition of the Ordnance Survey Ireland six-inch map, where it is shown as a circular area defined by a scarp, with a curving field boundary running to the east. By the time the 25-inch map was produced in 1897, surveyors recorded a slightly more oval form, measuring approximately 28 metres northwest to southeast and 21 metres northeast to southwest, with an external fosse running from the northwest around through north and east to the southeast. The monument's type has not been formally resolved, but the combination of a defined scarp and external ditch is consistent with the broader family of enclosed earthworks found across rural Ireland, ranging from ring forts used as farmsteads in the early medieval period to later enclosures of less certain function. What is clear is that the land around it has long since been brought into agricultural use, leaving the earthwork as a kind of residue, maintained more by the tree cover that has grown up around it than by any deliberate conservation effort.

An oblique aerial photograph taken in October 2002, along with more recent satellite imagery from between 2011 and 2013, shows the fosse still legible along the southern arc of the monument. On the ground, the trees that ring the enclosure are likely the most reliable guide to its location within what is otherwise unremarkable grazing land. Visiting in late autumn or winter, when leaf cover is thinner, gives the best chance of reading the earthwork's shape. The southern trace of the fosse noted in the aerial record is worth looking for specifically, as it suggests the ditch survives, at least partially, beyond the more obvious northern arc.
