The stone has a shallow basin deliberately ground into its surface, roughly 0.4 metres across, making it what archaeologists call a bullaun stone. Bullauns are found across Ireland, typically associated with early Christian or pre-Christian sacred sites; the basins are thought to have held water used in ritual or healing, though their precise function remains a matter of debate.

What makes this particular example quietly remarkable is its setting. The stone lies within a rath, a circular earthen enclosure of the kind commonly built as a farmstead or defended homestead during the early medieval period. That rath is itself enclosed within a promontory fort, an older and more substantial type of monument in which a headland is cut off by earthen banks or walls to create a naturally defended space. To the south-east of the bullaun, within the same rath, lies a children's burial ground, known in Irish as a killeen, where unbaptised infants were interred in a practice that persisted in rural Ireland well into the nineteenth and twentieth centuries. The bullaun sits to the north-west of this killeen, a spatial relationship that may be coincidental or may reflect an older logic of sacred organisation that is no longer fully legible. The antiquarian T. J. Westropp recorded the stone at least twice, in 1911 and again in 1914, describing it as a small rounded block with a ground basin; it was noted again by Casey in 1999.
