What makes this quietly interesting is not the absence itself, but the way the record of the site shifted between one map and the next, and then vanished from the ground entirely, leaving only a local memory of a house foundation behind.

When the first edition of the Ordnance Survey mapped this area, the site at Baile na bhFionnúrach appeared as a sub-circular enclosure, open to the south-west, with a rectangular building visible inside it. An enclosure of this kind typically refers to a defined area bounded by an earthen bank or stone wall, sometimes associated with early medieval settlement or farming activity. By the time the second edition of the OS map was produced, the opening to the south-west had disappeared from the cartographic record, and the site was shown as a complete circular enclosure. Whether that change reflected an alteration on the ground, a different surveyor's interpretation, or simply a tidying-up of the earlier sketch is now impossible to say. What the maps documented at two separate moments in time no longer corresponds to anything visible in the landscape. J. Cuppage recorded the site in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, noting that no physical remains were then apparent and that local knowledge had reduced the whole place to the memory of a house foundation.

The site sits in an area already dense with early Christian and prehistoric remains, on the slopes beneath a mountain long associated with St Brendan. That context makes the disappearance feel less like an isolated loss and more like a reminder of how much of the archaeological record of this peninsula survives only in layers: in maps, in surveys, in the diminishing recall of people who knew the land before it changed.
