Nobody knows what they were for. That small mystery sits at the centre of an otherwise fairly legible early medieval enclosure, a rath, which is the Irish term for a ringfort, typically a farmstead of the early historic period enclosed by one or more earthen banks. The unexplained stone setting is the detail that makes this particular example quietly arresting.

The rath sits on the low-lying plain east of Feohanagh, on the Dingle Peninsula in County Kerry, drained by the Feohanagh river. It is oval rather than circular, measuring roughly 42.6 metres east to west and about 30 metres north to south. The single earthen bank has been faced on both its inner and outer sides with drystone walling, a technique known as revetment, though the stonework shows considerable evidence of rebuilding and repair over the years, suggesting the enclosure remained in use or at least in memory long after its original construction. The bank rises to 1.4 metres on the interior side and 1.75 metres on the exterior. A fosse, the shallow external ditch that would originally have reinforced the bank's defensive or boundary function, survives only faintly along the south-western sector. There are entrance gaps at the south-west and east, measuring between one and 1.3 metres wide, though the eastern gap is now blocked. The north-eastern stretch of the bank has been absorbed into a townland boundary, and field fences radiate outward from the enclosure at several points, indicating how thoroughly early land divisions of this kind were folded into the agricultural landscape of later centuries. The site was documented by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula.

The interior ground is uneven in places, interrupted by natural rock outcrop, which makes the deliberate character of that stone alignment all the more noticeable. Whether it was a structural feature, a marker of some kind, or something else entirely, the survey recorded no firm answer.
