These are not freestanding high crosses of the kind that draw visitors to Monasterboice or Clonmacnoise; they are attached directly to the stonework, almost embedded in it, and easy to pass without registering what they are. One of the pair has short projecting arms and a splayed shaft, that is, a shaft that widens as it descends, a form sometimes associated with early medieval stonework in Ireland.

The crosses were compiled and documented by researchers Geraldine Stout and Padraig Clancy, with notes revised as recently as April 2018, though the church fabric itself is considerably older. Granite was the obvious local material on this stretch of the Dublin coast, and its use here ties the site into a broader tradition of ecclesiastical stoneworking across the county. The precise dating of the crosses is not recorded in the available notes, but their attachment to a medieval church wall suggests they have been in place for centuries, whether as devotional markers, boundary indicators, or decorative elements on the original structure.

The church sits off Marino Avenue West, a road that leads east from Killiney Hill Road. That approach is worth noting: Killiney Hill itself draws considerable foot traffic, but the church and its crosses tend to attract less attention than the views from the summit. Visitors looking for the crosses should head to the north wall once they reach the building, where both pieces can be examined at close range. The detail of the projecting arms and the widening shaft is subtle rather than dramatic, and the granite weathers in a way that makes careful looking worthwhile, especially on a day when low light picks out the texture of the stone.
