No headstones, no boundary wall, no low kerbing stones pushing up through the grass. A stream runs nearby, marking the edge of the townland, and that is more or less all that announces itself. The site sits in open grassland to the south of what was once Killeen Church, and were it not for the documentary record, there would be no way of knowing it had ever served as a burial ground at all.

The earliest reliable description comes from the Ordnance Survey Field Name Books, compiled in the early nineteenth century, which noted plainly that "the ruins of Killeen Church and burial ground for still born children is situated here." The first edition six-inch Ordnance Survey map, produced around the same period, depicted the church alongside a square-shaped graveyard adjoining its southern side, with the graveyard boundary rendered in dotted outline, a cartographic convention suggesting something already uncertain or degraded even then. By the time the revised editions of the OS maps were produced, the graveyard had disappeared from the record entirely. What the maps hint at, and the archaeology broadly supports, is a site with medieval origins that was later adapted, as happened in many parts of Ireland, into a cillin. A cillin, sometimes spelled killeen, was an unconsecrated burial ground used for those excluded from church burial: unbaptised infants above all, but also sometimes suicides or strangers. The word killeen embedded in the church's placename may itself preserve a memory of this function.

The site lies in the townland of Cowpark, with the townland boundary with Killeen roughly fifty metres to the west, marked by the stream. An aerial photograph taken in March 2006 as part of the Archaeological Survey of Ireland recorded no visible gravemarkers or boundary features from the air, and ground survey has confirmed the same absence at surface level. For anyone visiting, there is little to see in the conventional sense, which is rather the point. The grassland keeps its own counsel. What a visitor can do is orient themselves by the church remains to the north and look southward across the open ground, knowing that the dotted line on an old map once enclosed something that mattered quietly to the people who used it.
