It holds a place on the official map of Irish archaeological monuments, which means it was noted, named, and assigned a category at some point, but the details that would explain what it actually is, who was buried there, and when, remain effectively inaccessible to the general reader. That gap is itself a small curiosity. Ireland has thousands of such sites, ranging from Bronze Age cist graves, in which a body was placed in a stone-lined box set into the ground, to early medieval Christian burials, to post-medieval field interments, and without further information it is impossible to say which tradition this particular site belongs to, or what survives above ground.

Knocroe is a placename found in several counties across Ireland, and the Mayo instance sits within a landscape that has been farmed and settled for millennia. The west of Ireland preserves an unusually dense record of prehistoric and early historic activity, partly because the land was never as intensively developed as more easterly regions, and partly because bogland and thin soils have sometimes protected what lies beneath them. A burial recorded in such a landscape might be a solitary grave marker, a low mound, a scatter of bone, or something more structurally significant, but for this particular site, the surviving documentation has not yet been made publicly available.
