The Ordnance Survey's six-inch map of 1842 captured it as a circular earthwork roughly fifty metres across, the kind of boundary that in early medieval Ireland typically marked a sacred precinct around a church or oratory. Ecclesiastical enclosures of this type, often circular or oval in plan, were a common feature of the early Irish church, defining consecrated ground and the community gathered around it. This one did not survive long enough to be excavated or studied. It was removed by quarrying, leaving no visible trace on the ground.

The site may be the same one that the historian and antiquarian Patrick Power described in 1923, referring to an early church site on O'Brien's farm in the Ballyvodock area. The connection is not certain, but the geography fits. What Power recorded, and what the Victorian mapmakers drew, together suggest a site with genuine antiquity, a small piece of ecclesiastical organisation in the Cork landscape that has since been entirely erased. Its existence is now a matter of cartographic record rather than physical presence, a circle on an old map where something once mattered to people who built their religious lives around it.
