Rectangular walled graveyards of this kind are common enough across Ireland, but that subtle deviation in the boundary points to an earlier enclosure of a different shape, perhaps predating the medieval church whose remains still stand within the walls. It is the kind of detail easily missed by a passing driver, yet it quietly implies centuries of use and reuse on a single patch of north County Dublin ground.

The church itself, recorded under the reference DU015002001, is now largely reduced to its foundations, but one structure built directly over the site of the former nave is considerably more legible. A mausoleum marks the burial place of Austin Cooper, an antiquarian who died in 1830. Cooper was a collector and recorder of Irish antiquities at a time when such work was carried out by gentleman scholars rather than professional archaeologists, making it a certain irony that a man who spent his life documenting old things now rests inside one. Among the graveyard's older headstones, one dated 1754 commemorates Elias Reynolds and five of his children, all of whom died young. The stone was documented as part of the Fingal Historic Graveyards Project in 2008, and the graveyard as a whole contains markers spanning the eighteenth, nineteenth, and twentieth centuries.

The graveyard sits by the roadside and is accessible without any particular effort, though the medieval remains and mausoleum reward a slow circuit rather than a glance over the wall. The kink in the south-eastern boundary is easier to appreciate from inside the enclosure, where the slight change in angle becomes apparent against the otherwise straight line of the wall. For anyone with an interest in how burial grounds in Ireland accumulated layers of history across very long periods, this one in Kinsaley offers a compact and readable example.
