No wall surrounds it. No formal monument draws attention to it. Yet the arrangement is deliberate and well-preserved, and what it represents is one of the more quietly charged features of the Irish rural landscape: a children's burial ground, or cillín, a place set apart for those who could not, under older Church custom, be interred in consecrated ground.

Cilliní were used for centuries across Ireland to bury unbaptised infants, and sometimes others considered to exist outside the full rites of the Church, including stillborn children and occasionally strangers or suicides. The decision to use a ringfort, a circular earthwork enclosure typically dating from the early medieval period, as the location for such a ground is not unusual in itself; ringforts were often associated in folk memory with the older world, with liminal space, with the Otherworld, and were thus considered fitting, if unofficial, burial places. The Ballynagittagh example is noted by O'Flanagan in 1927, recording a roughly square unenclosed area measuring approximately 23 metres north to south and 21 metres east to west, with numerous set stones indicating individual graves oriented east to west, a orientation consistent with Christian burial practice even in these marginal contexts.

The site sits within the ringfort recorded separately in the Galway archaeological record, and the two features together, the ancient enclosure and the more recent children's ground within it, layer time in a way that is characteristic of Irish landscapes, where one era of use quietly accumulates on top of another without ceremony or explanation.
