The result is a D-shaped enclosure, roughly 45 metres across its longest axis and 35 metres across its shorter one, that sits with quiet authority above the gently rolling ground around it. The shape itself is a clue to age: D-shaped or curvilinear ecclesiastical enclosures are generally considered a hallmark of early medieval church sites in Ireland, the curved boundary reflecting a much older tradition of sacred space that predates the rectangular logic of later formal churchyards.

The parish church of Kilcooly stands within this enclosure, and the graveyard that surrounds it holds relatively few headstones, the earliest dating to around 1850 and the latest to 1987. That modest span suggests the site was not a heavily used burial ground in recent centuries, which in turn makes the prominence of the hillock and the elaborateness of the enclosure all the more curious. The graveyard sits within a broader ecclesiastical enclosure, and an associated field system lies approximately 100 metres to the north-west, hinting that what survives above ground is only part of a more extensive complex of activity that once organised this corner of Meath.
