It is the kind of monument that only reveals itself on paper, and even then only on old paper; the 1906 edition of the Ordnance Survey six-inch map shows a roughly circular form approximately 34.6 metres across on its north-south axis and around 38 metres east to west, defined by a scarp, a low earthen edge marking where the ground level changes. Enclosures of this type are among the most common early medieval monuments in Ireland, broadly comparable to a ringfort, a circular enclosed settlement used from roughly the fifth to the twelfth centuries, though without excavation the precise function and date of any individual example remains uncertain.

What the map also preserves is evidence of gradual erasure. A kink in the scarp in the south-west quadrant points to localised quarrying at some point, while a field boundary running east to west cuts through the northern quadrant, effectively truncating the monument. That boundary is itself depicted on the 1906 map as a hachured bank, meaning it was already well established by the time the surveyors passed through. A farm trackway running roughly east to west sits just to the north of the monument. The enclosure does not exist in isolation either; a large mound sits approximately 40 metres to the north, and a smaller mound lies immediately to the north-east, suggesting this corner of Camus once held a cluster of prehistoric or early medieval activity, now distributed across fields and farmyards with no obvious relationship to one another at ground level.
