It is remarkably small, measuring just 0.67 metres in length and 0.40 metres in width, and barely a centimetre thick. What sets it apart is not its size but what is worked into its surface: a Latin cross rendered in pecked outline, a technique whereby a craftsperson tapped the stone repeatedly with a pointed tool to trace a design rather than cutting clean incised lines. The result is rougher and more immediate than later carved work, and it places this small slab within a tradition of early medieval funerary marking that one might expect to encounter in a rural monastic site rather than on the southern fringes of a modern city.

Templeogue takes its name from the Irish Teampall Óg, meaning young or small church, and the ecclesiastical site here has early origins. The graveslab, catalogued under the reference DU022-0090001-, was recorded in the edited volume compiled by K. Swords and noted by archaeologist Geraldine Stout, who uploaded the record in April 2012. The slab is limestone, a material commonly used for such markers across Leinster, and its thinness, just nine millimetres, suggests it may have been shaped from a naturally flat piece of stone rather than heavily worked from a block. The pecked-outline Latin cross, a cross with arms of equal or near-equal length in the familiar upright form, is a type associated with early Christian burial practice in Ireland, though without additional inscription or iconographic detail it is difficult to assign a precise date.

The slab sits in the graveyard to the north of the church, and since Templeogue village is well within the Dublin suburban sprawl, the site is accessible without any particular difficulty. The graveyard itself is the thing to seek out rather than the church building, and once there it is worth taking time to look carefully at ground level, since a slab of this size can easily be overlooked among larger monuments. Low-angled light, particularly on an overcast day or in the earlier or later hours, tends to bring out the texture of pecked stonework far better than direct overhead sun, which can flatten surface detail and make the cross harder to read.
