There is no formal enclosure, no monument, no plaque. The stones are modest, and easy to miss unless you already know what you are looking for.

Places of this kind are known across Ireland as cillíní, informal burial grounds used for unbaptised infants and others who, under Catholic ecclesiastical tradition, could not be interred in consecrated ground. They tend to occupy liminal locations, cliff edges, bogs, boundaries between townlands, places that were somehow set apart. The site at Derrylough follows that pattern exactly: marginal ground, on the very edge of things, with the bay opening out below it. Local tradition holds that the upright stones here mark children's graves, and while no excavation or formal survey appears to have been carried out, that oral record is typically how the existence of such sites is preserved at all, passed down through families and neighbours long after the burials themselves ceased.
