There are no inscribed headstones, no family names, no dates. What covers the ground instead are low, moss-covered stones, most of them barely raising themselves above the grass, some slightly taller and oriented to face east. It is a cillín, the Irish term for an informal burial ground used for unbaptised children and others who, under Catholic doctrine, could not be interred in consecrated ground. These sites are found across Ireland, often tucked at field margins or beside old boundaries, and they tend to announce themselves only to those who already know to look.

The site measures roughly 18 metres east to west and 13 metres north to south, its outline defined by a low earthen and stone scarp that is best preserved on the south-western downslope side, where it compensates for the natural fall of the ground. It was already recorded by name on the Ordnance Survey six-inch map of 1842, appearing there as Tyredagh Burial Ground for Children, and again on the 1920 revision as Tyredagh Children's Burial Ground. That continuity across nearly eighty years of mapping suggests the site was well known locally and regarded as a fixed, recognised feature of the landscape, even if it never received the formal architecture of a parish cemetery.

Access is practical and, in its own way, telling. A set of stone steps, roughly two metres high, is built directly into the field boundary wall where it meets the tertiary road to the north, leading from the road straight into the interior of the burial ground. The steps are an intentional feature, not an afterthought, which points to a community that used this place with some regularity and wanted it to be reachable. Inside, the ground is partly shaded by trees growing along the enclosure's edge and occasionally within it. The uninscribed markers face east, as is consistent with Christian burial tradition orienting the body towards the rising sun, a detail that sits quietly alongside the site's exclusion from the official rites of the Church.
