Set horizontally into the external face of the south-western antae of a pre-Norman church, it was only identified as a likely cross-inscribed stone in early 2023. An antae, in Irish ecclesiastical architecture, refers to the projecting side walls of a church that extend beyond the gable end, a feature common in early medieval Irish stone churches. The slab's decoration is subtle rather than showy: a double-line shaft suggesting a cross, ending in a semi-circular terminal or knop. Whether it was always positioned here or was incorporated into the church fabric at a later point remains an open question.

The identification was made by Cormac Bourke in January 2023 and compiled by Caimin O'Brien as part of an ongoing effort to document the site's considerable early medieval and medieval remains. The church itself, with its later medieval chancel addition, sits on a low rise northeast of Kill Abbey Road, and the surrounding complex is notably dense with early Christian material. Alongside the church, the site preserves a graveyard, a holy well, a bullaun stone (a boulder or slab with one or more cup-like depressions, associated with early Christian ritual use), a separate cross-inscribed stone, a stone font, and the base of a stone cross. Two further crosses, which once stood along the former laneway leading into the graveyard, have since been removed and are now held in the care of the Office of Public Works in Trim, County Meath.

The site sits on a low rise in a green area, reached from Kill Abbey Road. Because the graveslab is set flush into the external stonework of the church wall rather than displayed as a freestanding object, it requires a careful eye and some prior knowledge to locate. The decoration is worn and the sandstone has weathered considerably, so good natural light, ideally on a clear morning, helps considerably when trying to make out the double-line shaft and its rounded terminal. Given the number of early medieval features concentrated in one place, it is worth moving slowly around the whole complex rather than focusing on any single element.
