It is subrectangular in plan, roughly 1.6 metres long and 0.3 metres wide, with its long axis oriented east to west. Alone in an unenclosed field, it is the kind of monument that rewards a second look from anyone who happens to pass.

What makes the site quietly puzzling is what the maps record. The Ordnance Survey six-inch maps of 1842 mark this location under the name Dallauns, and they show not one stone but two. The word dallaun, sometimes spelled dallán, refers to a small standing stone or pillar, often associated in folklore with early Christian commemoration or with older, less easily categorised ritual functions. Whether the second stone was already gone by the time anyone thought to record its physical dimensions, or whether it simply escaped later documentation, is not clear. The name alone, fixed on a nineteenth-century map, keeps the memory of a pair where now only one remains.
