The maps changed their spelling across the editions of 1842, 1904, and 1938, cycling through Dallaun, Gallaun, and Gallán, but the substance remained the same: one stone. What was eventually found on the ground, once the heavy overgrowth was pushed back, was something rather different.

There are in fact three stones, and they are arranged in a triangle. The tallest, measuring 1.72 metres in length and 0.88 metres wide, once stood at the apex of that triangle but has since fallen. The two upright stones are set 3.2 metres apart from each other, and each sits approximately 2.5 metres from the fallen apex stone. Researcher P.J.H. Hartnett documented this triangular configuration, which shifts the site's likely character considerably. A lone gallán is a fairly common feature of the Irish landscape, often interpreted as a boundary marker or a monument to the dead. A group of three stones arranged with apparent geometric intention is rarer and harder to categorise, which may be part of why the classification here carries the word "anomalous" rather than assigning it to any tidy monument type. Adding another layer to the site's context, a ringfort, the remains of a roughly circular earthen enclosure of the early medieval period, lies approximately sixty metres to the west-northwest, just inside the corner of the same field. Whether the stones and the ringfort were ever related in use is not known, but their proximity in a working tillage field gives the place an accidental quality of layering, different eras of human activity occupying the same small patch of ground.
