The Irish, Lisín na nGarlach, translates as the little ringfort of the children, and that designation points not to a place of settlement or defence, but to a killeen, a cillín, one of those small informal burial grounds used for unbaptised infants and others who could not, under Catholic practice, be interred in consecrated ground. The physical remains are slight: a sub-circular mound roughly 11 metres by 13 metres and just half a metre high, with faint traces of two fieldbanks still visible running into the site from the southeast and southwest.

The site began its life as a ringfort, a rath, the kind of circular earthwork enclosure that dots the Irish countryside in the thousands, typically dating from the early medieval period and used as a farmstead or family compound. Over centuries, many such enclosures were repurposed or simply absorbed into later land use. At Bunagarha, the old earthwork became a killeen, and local memory holds that it remained in use as a burial ground right through the Famine period of the 1840s. The name Lisheennagaurlagh preserves that history in compressed form, the diminutive lisseen for a small lis or ringfort, combined with the word for children, garlach in the plural. It is a rare case where a place-name functions almost as a monument in its own right, more durable than the earthwork itself.

The mound is modest enough that a visitor unfamiliar with killeen burials might pass it without a second thought. What gives it weight is the context: across Ireland, hundreds of these informal burial grounds occupy the margins of older earthworks, field boundaries, or shorelines, places already set apart from ordinary use, already carrying some sense of the liminal. The children buried here left no marked graves. The site itself has barely held its shape. But the name has endured.
