Near Kilgulbin in north County Kerry, there was once a circular enclosure, the kind known in Irish as a lios, a ringfort built to define a farmstead and its household. Today there is nothing left to see. No earthwork, no bank, no depression in the grass. The site exists now only as a cartographic ghost and a name.

The enclosure appears on Ordnance Survey maps from both 1841 to 1842 and 1898, which tells us it was recognisable as a feature in the landscape for at least the latter half of the nineteenth century, even if already degraded by then. Its Irish name, Liosanna Bhaile Sheonaic, translates roughly as the ringfort of the homestead of Seonac, Seonac being a personal name, suggesting the site was associated with an individual or family in local memory long before any map-maker arrived. The enclosure sits north-east of a rocky outcrop and immediately south of a related recorded site, hinting at a small cluster of features in this part of the parish. C. Toal's North Kerry Archaeological Survey, published in 1995, placed it in this broader landscape context, though even by that point no surface trace remained.
