Bullauns are granite or other stone boulders bearing one or more deliberately hollowed basins, and they appear across Ireland in contexts ranging from early medieval monastic sites to isolated fields, their original purpose still debated. This one is substantial: over a metre long and half a metre high, with a single basin measuring roughly 0.6 by 0.4 metres that takes up much of the boulder's upper surface.

The stone came to light not through any formal excavation but through the practical business of cutting a new road. When the landowner was bulldozing a roadway to reach his workshop to the south-east of the house, the blade turned up this granite boulder. It now sits in the front garden, absorbed into the landscaping as if it had always belonged there. The field in which the house stands is locally known as Liss Hill, a name worth pausing over: "liss" or "lis" typically refers to a ringfort, the circular earthen enclosures used as farmsteads in early medieval Ireland, and such place names often persist long after any physical remains have been levelled. Whether a ringfort ever stood here is unrecorded, but the name suggests the land carries a longer history than its current appearance might suggest.
