These sites, known variously as cillíní or children's burial grounds, were used for infants who died before baptism, and sometimes for others considered ineligible for formal Christian burial. They occupy a peculiar category in the Irish landscape, neither fully sacred nor wholly forgotten, and this one at Carrigane is now so levelled that only the faint outline of its enclosing bank survives.

The Ordnance Survey mapped the site in 1841 to 1842 under the name 'Kyle burial ground', a designation that did not carry forward to later editions, leaving it without any formal label on the revised maps. What remains today is a roughly rectangular earthwork, oriented broadly north to south, measuring approximately 20 metres by 45 metres, with a bank rising no more than 0.6 metres at its highest point. Just to the east lies a ringfort, one of those circular enclosures, typically of early medieval date, that once served as a defended farmstead. The proximity of the two features is not unusual in the Irish landscape, where such burial grounds were often established at or near older earthworks, perhaps because these already-marginal places felt appropriate for those who existed on the edges of formal religious practice.

The mound itself is unassuming to the point of near-invisibility, and without prior knowledge there is little to indicate what it once was. The name 'Kyle' may derive from the Irish coill, meaning a wood or grove, suggesting the area may once have had tree cover that has long since disappeared.
