What remains of this possible cashel, a type of ringfort built from unmortared stone rather than earth and timber, is now little more than a low, grass-covered ridge, its outline traced more by vegetation than by any obvious masonry. The wall, which originally stood several courses high and measured between 2.2 and 2.8 metres in width, has collapsed so thoroughly that its interior height barely reaches half a metre above the ground. Furze, brambles, and briars have colonised the south-western arc, and thorn bushes have taken root inside the enclosure itself, turning the space once enclosed into a small, tangled thicket.

The site sits within the western half of a relict field system, meaning the ghostly outlines of older agricultural boundaries still pattern the surrounding land, suggesting this was once an organised and inhabited landscape. The cashel is roughly subcircular in plan and measures approximately 27.8 metres east to west. Its northern sector is noticeably irregular, partly because outcropping limestone disrupts the line of the wall, a reminder that this part of Galway sits on the same karst geology that shapes the wider Connacht landscape. The interior slopes gently to the south-west, and limestone breaks the surface there too. Aerial photography from 1995 revealed something that is largely invisible from ground level: a smaller subcircular enclosure or annexe, roughly 12 metres east to west and 10 metres north to south, immediately to the west of the main cashel. Such annexes are known from other cashel sites and may have served as enclosures for livestock or as subsidiary working areas. A second enclosure lies approximately 125 metres to the north-east, suggesting this corner of Stonepark was once more densely settled than its current appearance implies.
