In the south-east corner of the graveyard at Ballymore Eustace, a granite slab sits low and earthfast, tilted slightly upright from the ground as though it never quite decided whether it was a marker or a monument. It is modest by any measure, tapering from around half a metre wide at its base to a narrower top, and standing less than a metre tall. What lifts it out of the ordinary is the incised Latin cross cut into its eastern face, a simple linear cross carved directly into the stone rather than raised in relief, the kind of marking that required little in the way of craft but carried considerable weight in meaning.

Slabs of this type are among the older categories of grave marker found at early ecclesiastical sites across Ireland. An earthfast slab, meaning one set directly into the ground rather than mounted on a base, typically belongs to the early medieval period, when the marking of individual graves was a spare, functional act. The cross on the eastern face is significant in orientation, the east being the direction of the rising sun and, in Christian tradition, the direction of resurrection. This particular slab is recorded as Slab 6 in Corlett's 2003 study of the site, which places it within a broader group of similar stones at Ballymore Eustace. It stands beside a high cross, a type of elaborately carved freestanding stone cross more familiar from major monastic sites, making this corner of the graveyard an unusually concentrated gathering of early stonework.
