Enclosures of this kind are among the most common yet least understood monuments in the Irish countryside. They might be the remains of a ringfort, a roughly circular earthen or stone-walled settlement used from the early medieval period onward, or something older altogether, a field boundary, a ritual space, or a stock enclosure whose original purpose has long dissolved into the land itself. Kerry is dense with such features, many of them unmarked on casual maps and unvisited except by those who already know to look.
