The low stones inside carry no inscriptions, no names, no dates; they mark only the fact of burial. This is a cillín, a type of informal burial ground once used throughout Ireland for unbaptised infants and others excluded from consecrated churchyard soil, including stillborn children, and in some cases suicides or strangers. Such places tend to occupy the margins, physically and socially, tucked into field corners or ancient boundaries, neither commemorated nor entirely forgotten.

The site at Caherloghan is subtriangular in shape, roughly 26 metres across its longest axis, and is defined by a low earthen bank that curves around the south and south-east, while the northern and north-eastern edges appear to have been absorbed into the existing field boundary system. The boundary itself, of earth and stone construction, stands between half a metre and three-quarters of a metre high on those sides. Both the 25-inch Ordnance Survey map and the 1921 six-inch edition record the site, naming it Killoghan Children's Burial Ground, which suggests it was already understood as a distinct and named place well into the twentieth century. The gravemarkers that survive within the scrub are small, raw, and unworked, ranging from roughly 20 to 40 centimetres in height, and some loose stone nearby may have come from field clearance rather than intentional marking.

The enclosure sits in lush pasture, and its interior, partially grass-covered but largely dominated by dense scrub, gives little away at a glance. The whitethorn, traditionally associated in Irish folk belief with the threshold between worlds, has grown thickly over the stones. The bank at the south-east corner remains the most legible structural feature, while the northern corner has a short section of field boundary extending outward along a north-west to south-east axis, blurring the line between the monument and the ordinary agricultural landscape around it.
