Barely eighteen centimetres high and just over a metre across, it sits at the eastern edge of a rectangular enclosure, its circular form defined by a kerb of firm stones set around its base. The earth immediately surrounding it dips slightly, which is one of the details that distinguishes a genuine ancient monument from a natural undulation. This is a mound barrow, a type of burial monument typically raised during the Bronze Age, in which a low earthen or stone mound was constructed over a burial, sometimes accompanied by grave goods.

What makes the site in Rathcoun quietly interesting is not the barrow in isolation but its relationship to the surrounding landscape. Just fourteen metres to the north-north-east lies a ditch barrow, a related monument type where a circular bank and ditch define the funerary space rather than a solid mound. Thirty-six metres to the west-north-west sits a small possible cairn, a loose pile of stones that may represent yet another form of prehistoric funerary or ritual deposit. Together, these three features suggest that this corner of Tipperary was not a place of single, incidental burial but something more deliberate, a cluster of monuments occupying ground that commanded wide views across the landscape to the east, north-east, and north-west. That orientation towards open ground is a pattern recognised at many prehistoric burial sites across Ireland, where visibility and elevated sightlines seem to have mattered to the people who chose the location.
