The slab itself is modest to the point of near-invisibility, measuring just twenty centimetres in height, fourteen wide, and fourteen deep, with the base of the cross shaft still buried beneath the soil. That partial concealment is a quiet reminder of how much early Christian stonework remains half-swallowed by the ground it once marked.

Children's burial grounds of this kind, known in Irish as cillíní, were used for the interment of unbaptised infants and others who, under Catholic teaching, were excluded from consecrated ground. They are found across Ireland, often at ancient or marginal sites, and frequently contain early medieval stonework repurposed or simply left in place over the centuries. At Eochaill, the cross-slab sits roughly five metres to the west of a second stone, a broken pillar also bearing a cross inscription, which suggests the site held at least modest significance in early Christian practice. The cross form on the slab, a Latin cross with its distinctive wedge-shaped or expanded terminals, is consistent with early medieval Irish carving traditions, where such terminals were a common decorative feature on memorial and boundary stones alike.
