A kerb circle is a prehistoric monument type in which upright or edge-set stones define the outer boundary of a low, slightly raised earthen or stony platform, in effect a monumental kerb rather than a true stone circle. This one originally measured roughly 22 metres east to west and 10 metres north to south, with individual stones ranging up to 2.75 metres in length and over a metre in height, substantial blocks by any measure. What survives is only roughly semicircular, the southern portion having been dismantled around 1970 when stones and a fence line were removed, presumably in the course of agricultural improvement. The interior has since been used for dumping field clearance material, so the low raised platform that once defined the space is now obscured beneath the debris of generations of farming.

The site was catalogued by Seán Ó Nualláin in a 1984 study of the monument type, which placed it alongside comparable sites at Gortnahown, Knockaunavaddreen, and Moneen in the same county. These comparisons suggest the Cuppage monument belongs to a recognised regional tradition of kerb-defined enclosures, likely prehistoric in origin, though the ruined condition of this example makes closer dating or interpretation difficult. The use of local sandstone, set in a kerb fashion to delimit a platform only about half a metre high, is consistent with what survives at the related sites. Whatever ritual, funerary, or communal function the monument once served, it has been significantly altered by the events of the last half-century, leaving a site that is more absence than presence, a shape that only becomes legible once you know what to look for.
