Both stones are now incorporated into a field boundary, their prehistoric alignment absorbed into the practical geometry of a working farm. Yet the arrangement is deliberate and old: the pair stand 1.1 metres apart, oriented along a northeast to southwest axis, with a combined length of around 3.2 metres. The larger of the two, at the southwest end, reaches 1.5 metres in height; its companion to the northeast stands just a little shorter at 1.4 metres. Standing stones of this kind, erected in pairs or short rows, are a recurring feature of the prehistoric landscape of West Cork, though their original purpose remains a matter of debate, with theories ranging from territorial markers to ceremonial alignments.

What makes the Keilnascarta pair particularly interesting is that it does not stand alone. Roughly 100 metres to the north-northwest lies a stone row, a linear arrangement of three or more standing stones, and approximately 150 metres in the same direction is a second pair of standing stones. The clustering of these monuments suggests that this gentle south-facing slope was a place of some significance in prehistory, deliberately chosen and repeatedly returned to. Scholars including Ó Nualláin and Roberts documented these sites in the late 1980s as part of broader surveys of Cork's prehistoric monuments, and the Keilnascarta grouping features in both bodies of work. Such concentrations are not unusual in West Cork, a region that preserves one of the densest assemblages of Bronze Age stone monuments in Ireland, but the proximity of three distinct monument types within 150 metres of one another gives this particular corner of the landscape a quietly layered quality.
