Sixteen metres across, the enclosure is defined by a sod-covered bank of stone, nowhere much taller than a person's shin above the surrounding ground. Its walls have slumped and merged with later field boundaries over what is likely a very long period of time, and a planted line of conifers now follows the course of the fence that has swallowed part of the south-eastern arc. What was once a deliberately bounded space now reads as little more than a slight thickening in the ground.

Enclosures of this kind, roughly circular and defined by a low stone bank, are found across Ireland and can date to anywhere from the prehistoric period through to the early medieval centuries. They may have served as settlement enclosures, stock pounds, or spaces with ritual significance, and their purpose is rarely obvious from surface remains alone. At Srahyconigaun, three gaps interrupt the circuit: a narrow break at the north-north-east, a wider one at the north-east, and a third to the east that a modern field fence has since blocked. Whether any of these openings represent original entrances is unclear. More suggestive is the oval depression inside the southern portion of the enclosure, roughly four metres at its longest and half a metre deep, grassed over but still legible as a hollow. Such depressions within enclosures sometimes indicate the footprint of a structure, though without excavation it remains speculation. The broader slump on the north-western exterior may simply reflect generations of farmers clearing stones from nearby fields and depositing them against the most convenient existing bank.
