A cashel is a type of early medieval stone ringfort, a roughly circular enclosure built from dry-stone walling, and the structure in question sits inside one, half-absorbed back into the landscape. The wall defining it is only about a quarter of a metre high now, grassed over and easily mistaken for a natural rise in the ground, but its dimensions are deliberate: roughly eight metres along a north-west to south-east axis, with walls about a metre thick.

What makes this particular feature quietly interesting is how little can be said about it with certainty. The form is subrectangular, which places it within a broad tradition of vernacular Irish building that spans many centuries, but the archaeological record stops there. A separate and larger subrectangular enclosure occupies the north-west quadrant of the same cashel, suggesting that whoever used this site over time arranged different structures within the protected space of the ringfort's walls, perhaps for different purposes or at different periods. The relationship between the two enclosures, and their relationship to the cashel itself, remains unresolved.
