A chest tomb is exactly what the name suggests, a box-like stone structure, typically rectangular, raised above the ground on side slabs and capped with a flat top stone. This one is missing one of its side stones and its top slab entirely, leaving the structure open and exposed. What makes it quietly puzzling is where that missing top slab may have ended up: a stone slab now standing upright on its side inside the church nearby is thought to be from this very tomb, separated from its original position at some unknown point and repurposed, or simply moved for safekeeping.

The slab carries an inscription that is only partially legible, complicated further by the fact that some of the text runs below the current ground level, buried under centuries of accumulated soil. What can be read points to the Casey family. The date 1783 appears twice, and a P. Casey is named both as the person commemorated and, it seems, as the one who arranged for the tomb to be made, the inscription reading in part that it was erected by P. Casey for himself and others. A later date, beginning 185, is also present but trails off into illegibility, suggesting the tomb was used or added to again in the mid-nineteenth century. The fragmentary nature of the text gives the monument an unresolved quality, a family record interrupted mid-sentence, with names and relationships that can only be guessed at from what remains above ground.
