It would be easy to step over it without a second glance, yet the hollow carved into its upper surface, steep-sided and deliberately shaped, marks it out as something altogether more purposeful. This is a bullaun stone, a type of ancient carved rock found across Ireland and generally associated with early Christian or pre-Christian ritual use. The defining feature is the basin, or bullaun, ground into the surface, which in many examples was thought to hold water with curative or protective properties.

The stone at Drumnanangle is a compact, roughly subrectangular block, measuring about 0.8 metres north to south and 0.7 metres wide, and embedded firmly in the pasture. The main hollow takes up most of the upper surface, measuring 0.35 metres across and 0.25 metres deep, with unusually high, steep sides. At the northern edge, there is a roughly V-shaped notch that breaks the rim, leaving only a low lip of stone on that side rather than the full enclosure found elsewhere around the basin. Immediately to the south of this large hollow, a smaller and much shallower oval depression sits on the same surface, measuring roughly 0.24 metres east to west and 0.14 metres north to south. Whether this secondary depression was deliberately worked or is a product of natural weathering is unclear, but its proximity to the main hollow invites the question. Just up the slope from where the stone lies, a raised area is identified by local tradition as the site of a church, a connection that echoes the pattern seen at many bullaun stones across Ireland, where such carved stones tend to cluster near early ecclesiastical sites.
