The stones are arranged in north-to-south running rows, with the graves themselves oriented east-west, the traditional Christian alignment placing the body to face the rising sun. One or two rectangular grave plots are also visible among them. What makes the place quietly distinct is its classification as a children's burial ground, known in Irish tradition as a cillín, a category of site that once existed in its hundreds across the country.

Cilliní were unofficial burial grounds used for those excluded from consecrated churchyards, most commonly unbaptised infants, though in different periods and places the category extended to stillborn children, women who died in childbirth, and others considered to stand outside the full rites of the Church. They tend to occupy liminal locations, field edges, old ringfort interiors, or spots already felt to carry some older sanctity. This one sits near Knockmaa, a hill in east Galway long associated in local tradition with Finvarra, the legendary king of the Connacht fairies, which adds a layer of folkloric resonance to an already atmospheric setting. The enclosure is partially defined by a collapsed stone wall along its western and northern sides, giving it a rough trapezoidal shape measuring roughly 14.7 metres east to west and up to 12.3 metres north to south. That boundary, even in its ruined state, marks a deliberate separation of this ground from the surrounding fields.

The site sits in open grassland and the stones are set rather than upright monuments, so a visitor without some foreknowledge might walk across it without quite registering what it is. The collapsed wall gives the clearest sense of the enclosure's original extent, and the rows of set stones become more legible once the eye adjusts to the pattern.
