Carved or worn into its upper surface is a deep circular depression, measuring about 35 centimetres across and 20 centimetres deep, and resting inside that hollow is a large, rounded sandstone rock. A number of smaller stones cluster around the base. This is a bullaun stone, a type of ancient boulder bearing one or more cup-like basins that are found across Ireland, frequently in association with early Christian sites or holy wells. Their precise function remains a matter of debate, but they were often attributed with curative or ritual properties, and the loose stones placed in the depressions were sometimes rotated as part of devotional practice.

The stone itself measures roughly 86 centimetres by 78 centimetres and sits only 27 centimetres proud of the ground, giving it a low, settled presence in the landscape. What lends the Kyle example a particular quietness is the near-total absence of any obvious ecclesiastical monument nearby. The townland name, however, offers a clue. Kyle derives from the Irish word for a wood or narrow strait, but in this part of Tipperary it is thought to point toward the former presence of a church, one that has since vanished entirely from the ground. Bullaun stones were commonly associated with early medieval monastic enclosures, and their survival in fields where every other trace of a religious site has disappeared is not unusual. The stone and its carefully placed sandstone ball may be the last legible remnant of a small ecclesiastical community that otherwise left no mark.
