The cairn is roughly subcircular, measuring around 13.5 metres north-west to south-east and 12.5 metres north to south, and rises to less than two metres at its highest point. Its southern half has been partly obscured by field-clearance rubble dumped there at some point, the casual disposal of agricultural tidying gradually merging with whatever the mound once was. A curving drystone wall wraps around it from the south-west to the west, suggesting someone, at some time, felt it worth at least partially enclosing.

The cairn sits about 165 metres to the east-south-east of the church at the Drumacoo monastic complex, which places it within the broader orbit of an early ecclesiastical landscape. Near its north-western edge, a cross-base and fragments of a shaft survive, along with what may be a leacht, a low commemorative cairn or platform of stones associated with early Irish Christian devotional practice, sometimes marking a burial or serving as a focus for prayer. These elements together suggest the mound is not simply a field clearance feature but something older, layered into a site that accumulated religious and funerary significance over centuries. Precisely when the cairn was raised, and for whom, is not recorded.
