What makes it unusual is the arrangement of eight stones set radially within that bank, like spokes in a wheel, each between thirty and sixty centimetres high. Radial-stone enclosures are rare and not fully understood, which makes even a modest example like this one quietly compelling.

The enclosure's interior was used as a cillin, a term for an informal burial ground, typically associated with unbaptised infants, who were excluded from consecrated ground under pre-modern Catholic practice. These sites were often located at liminal places, field boundaries, ancient earthworks, or pre-Christian enclosures, and the choice of this particular spot suggests the community recognised something already old and bounded about it. The structural form, stones arranged radially within a circular bank, predates any Christian use, though precisely when the enclosure was first constructed is not known. Its position in the basin of the Durrus headwaters, a quiet upland setting well away from any obvious settlement centre, adds to the sense that this was a place set apart long before it became a burial ground.
