In the townland of Dromkeen in north County Kerry, a ringfort once known as Lisnacallee, or in Irish Lios na Caillí, the ringfort of the hag, has been completely levelled and left no visible trace on the ground. A ringfort, or rath, is a type of enclosed farmstead common across early medieval Ireland, typically defined by one or more circular earthen banks, and thousands survive across the country. This one does not, yet its name alone carries a particular charge. The "hag" in Irish placenames often refers to a supernatural female figure, the Cailleach, associated in folklore with ancient landscapes, winter, and the shaping of the land itself. That a vanished enclosure should carry her name feels quietly apt.

What makes Lisnacallee especially layered is that the earlier of the two Ordnance Survey maps on which it appears, produced between 1841 and 1842, records something additional: a cave marked within the interior of the enclosure. Caves or souterrains, which are underground stone-lined passages often associated with ringforts and thought to have served for storage or refuge, were not unusual features of such sites, though a natural cave would have been rarer and perhaps more significant to those who built and named the fort. By the time the 1916 edition of the OS map was drawn, the site was still being recorded, suggesting it survived into the early twentieth century in some recognisable form. At some point after that, it was cleared entirely, most likely through agricultural improvement, leaving only the cartographic record and the old name as evidence of its existence.
