By the time Ordnance Survey mappers revised their six-inch sheets in 1916, they recorded the site with the cautious notation "Burial Gd. (Site of)", that parenthetical already signalling something half-lost. On the earlier 1838 survey, it does not appear at all, suggesting the ground had already faded from confident record by the time the first systematic mapping of Ireland was under way.

The burial ground sits within an ecclesiastical enclosure, the kind of roughly circular or oval boundary, typically defined by an earthen bank or wall, that demarcates an early Irish Christian settlement. Inside this one stood two churches, and the space between and around them served as a place of burial. The association is entirely typical of early medieval Irish ecclesiastical sites, where the sacred ground enclosed by the vallum, or enclosing bank, would receive the dead of the surrounding community across many generations. What makes Crossbeg quietly curious is how completely the evidence has since disappeared. No grave markers, no surface disturbance, no visible trace remains to indicate that people were once laid here within the shelter of those church walls.
