It sits above a sharp drop in the land to the north and east, and the interior tilts gently downward in the same direction. What makes it quietly unsettling is the name. Both the enclosure and the field it occupies have long been called the "kill", a placename element derived from the Irish "cill", meaning a church or early monastic cell. Landowners have described it as a former burial place, and the earthworks themselves appear to form only the eastern half of what may once have been a larger early ecclesiastical enclosure.

The site was noted by Hartnett in 1939, who recorded the "kill" placename, a detail that points toward early medieval religious use of a kind well attested across Ireland. Small enclosed cemeteries and oratories, often roughly oval or rectangular and defined by a simple bank or scarp, were a characteristic feature of the early Irish church, frequently sited on elevated or liminal ground. The northern half of this enclosure is thought to contain a souterrain, an underground stone-lined passage of the sort typically associated with early medieval settlements, used variously for storage or refuge. A scarp running east to west bisects the southern half of the interior, adding a second layer of topographic complexity that is not yet fully explained. When O Nualláin revisited the site in 1988, the landowner confirmed the burial tradition, though no formal excavation appears to have taken place to test it. The possibility that the enclosure is only half of a larger complex gives the whole site an unresolved quality, as though the evidence has been preserved just enough to raise the question without answering it.
