It is a cillín, a children's burial ground, of the kind once found across rural Ireland, where unbaptised infants and others excluded from consecrated ground were laid to rest in unconsecrated but nonetheless carefully maintained spaces. What makes this particular example quietly arresting is the density and variety of what survives inside it: row upon row of small upright limestone slabs, most of them unworked and barely ankle-high, marking graves in the southern half of the enclosure with a kind of austere, understated order.

The site was recorded on the Ordnance Survey six-inch maps of both 1842 and 1920 as Ballygastell Grave Yard, and appears on Tim Robinson's 1977 map under the Irish name Cill Bhaile Uí Ghaistéil. The enclosure measures roughly 29.5 metres north to south and 22.6 metres east to west, its boundary formed by a collapsed, grass-covered wall of earth and stone in which upright limestone slabs are still intermittently visible on both inner and outer faces. Along the southern edge, a shallow nettle-filled depression running parallel to the wall may be the trace of an external fosse, a defensive or boundary ditch, suggesting the enclosure was more formally constructed than its current ruinous state implies. A barely perceptible scarp at the south-east corner is likely the remnant of an original entrance. Inside, the southern half is the most legible, with limestone slabs arranged in rows oriented north to south, particularly in the south-west quadrant. Several are finely shaped despite the plainness of the majority. Near the western edge stands a more prominent upright, classified separately as a standing stone. In the south-east corner, a low oval platform of earth and stone, roughly four metres by three, carries a prone limestone slab on its western edge and a worked, slightly leaning upright at its south-east edge, a feature whose purpose is not entirely clear but which reads as deliberately constructed rather than incidental.

The interior is overgrown and the boundary wall largely collapsed, but the rows of grave markers in the southern half remain visible, and the low undulations across the northern section may conceal further uprights beneath the grass. The site sits within open pastureland with wide views in most directions, accessible via a small cattle gap on the southern side.
