A bullaun stone is a natural or worked rock bearing one or more artificial cup-shaped hollows, ground into the upper surface; they are found widely across Ireland and are generally associated with early ecclesiastical or ritual sites. This example measures roughly 1.5 metres by 1.25 metres and stands about 0.6 metres high, with a single circular depression in its upper surface around 0.32 to 0.34 metres in diameter and 0.14 metres deep.

What makes its present position particularly telling is that this is not where the stone began. Local information indicates it was originally located some 50 metres to the north, within or beside an enclosure, the kind of roughly circular earthwork commonly associated with early medieval settlement or monastic activity in this part of Ireland. When that enclosure was levelled, the boulder was moved to the field wall where it now rests. The levelling of such enclosures was a common consequence of agricultural improvement and land clearance, and it frequently resulted in the scattering of associated features. In this case, at least the stone itself was preserved, even if its relationship to the enclosure it once accompanied is now a matter of local memory rather than visible landscape.
