A caher is a type of stone-walled ringfort, typically dating from the early medieval period, and what makes this site quietly puzzling is that the visible structures appear to be comparatively modern additions, yet they may well be sitting on top of something considerably older.

The uncertainty hinges on an earlier account. A researcher named Henry, writing in 1957, described three round stone huts at the site, placing them in roughly the same northern sector where the later structures now stand. Whether those huts survive beneath the current features, were incorporated into them, or simply disappeared in the intervening decades is not clear. It is the kind of stratigraphic ambiguity that fieldwork in Ireland frequently throws up, where successive generations have built, rebuilt, and borrowed stone from whatever was already there, leaving the archaeological record layered and difficult to read cleanly.
