A bullaun is a large rock, usually glacial or naturally occurring, into which one or more bowl-shaped depressions have been ground, either by human hands or, in some cases, by natural weathering processes. The two are not always easy to distinguish, which is part of what makes bullauns so consistently interesting to archaeologists and folklorists alike. They are found across Ireland, often near early ecclesiastical sites, and have accumulated centuries of ritual use, with the water that collects in their hollows traditionally regarded as having curative or protective properties.

The association between bullaun stones and early Christian activity in Ireland is well established, though their origins likely predate Christianity in many instances. Communities folded them into devotional practice, using the collected rainwater for blessing, healing, or cursing, depending on the tradition. Some bullauns retain small rounded stones within their hollows, known as cursing stones, which were rotated as part of rituals. Whether the Feagh stone retains any such features is not currently documented in accessible records, and the details of its precise condition, setting, and immediate surroundings remain to be fully recorded. What is known is that it has been identified as a monument worthy of note in the Clare landscape, placed among a county that holds a considerable number of such stones, often tucked beside ruined churches, holy wells, or field boundaries where early settlement once clustered.
