Measuring roughly nineteen metres at its widest and just over twelve metres across, it sits unmarked in the landscape, its boundary defined by nothing more than the arrangement of stones within it.

The stones themselves are set in alignment, running roughly north-northeast to south-southwest, indicating that the graves beneath follow a west-northwest to east-southeast orientation. That east-facing arrangement is a common feature of Christian burial practice, rooted in the expectation of resurrection from the east, though the absence of any enclosure here sets this site apart from a formally consecrated churchyard. The site is believed to be a children's burial ground, a category of place known in Irish as a cillín, a term referring to informal or unconsecrated burial grounds used historically for unbaptised infants, and in some cases for others considered ineligible for burial in sanctified ground. These sites tend to occupy marginal land, field edges, or old earthworks, and were often known locally for generations while remaining unrecorded in any official capacity. The Cappagh Beg example, in its unenclosed and quietly understated form, fits that pattern closely.

The notes on this site are spare, and that sparseness is itself telling. There are no inscribed stones, no known dates, and no documented names associated with it. What survives is a shape in the ground, a handful of set stones, and an orientation that speaks to the beliefs, and the losses, of the people who placed them there.
