The structure at Baile An Lochaigh is a subrectangular foundation, roughly 3.3 metres by 2.5 metres internally, its drystone walls, built without mortar by stacking and interlocking stone, surviving to no more than 0.8 metres in height. It is the kind of thing a walker might step over without registering, and yet it ended up catalogued alongside ringforts and ogham stones.

The Dingle Peninsula archaeological survey, published in 1986 by J. Cuppage under the Irish-language title Corca Dhuibhne, documented the built environment of this part of Kerry with unusual thoroughness, and this sheepfold appears among its entries. The survey assessed the structure as probably of fairly recent origin, which in archaeological terms can mean anything from a few decades to a couple of centuries old. What it tells us, more than anything, is that the land here was actively farmed within living or near-living memory, and that the same drystone building tradition used to construct ancient field walls and enclosures persisted, without much variation in technique, into the modern era. The continuity is quiet but real.
