It is a graveslab repurposed or repositioned so that it faces outward, its broad end uppermost, rising just over a metre above the ground. That detail alone sets it apart from the usual arrangement of such stones.

The slab is trapezoidal in shape and cut from granite, the local material of the Wicklow uplands. Its upper end carries a cross, not carved in relief but defined by a shallow groove barely two to three millimetres wide, with two further grooves running downward toward ground level. The technique is restrained, almost tentative. A second graveslab inside the church shares the same basic style, the same grammar of incised line and simple cross form, but the outdoor stone is noticeably cruder in execution, suggesting either a different hand or a later, less skilled attempt to work in an established local tradition. Early medieval graveslabs of this kind, where ornament is reduced to a grooved outline rather than sculpted form, are found at a number of ecclesiastical sites across Ireland, and they tend to cluster around early church foundations where the tradition of marking individual graves with shaped stones was taking hold.
