The site at Killogunra carries the remains of a graveyard, and possibly a church, that did not appear on the Ordnance Survey's first detailed mapping of Ireland in 1838. By the time the 25-inch plan was drawn, the area had been annotated as both a burial ground and the site of Killogunra Church, though by the 1922 revision of the 6-inch map the outline of the burial ground had already been dropped, leaving only the place-name as a marker. What precisely happened in the intervening decades, and what the site looked like at any of these moments, is not fully clear.

What remains on the ground today is a roughly square enclosure defined by grassed-over wall footings, measuring approximately 14.2 metres east-to-west and 13 metres north-to-south, with walls around 0.8 metres thick. The interior is filled with rubble. Whether these footings are the walls of the church itself, a boundary defining the burial area, or some combination of the two has not been firmly established. The distinction matters: early Irish ecclesiastical sites often enclosed a burial ground within a low surrounding wall, and the church building would have stood separately inside that precinct. Here, the evidence does not yet clearly separate the two possibilities. What local tradition has preserved, however, is the memory of a stone set into the south-westerly wall that is said to carry miraculous powers. Such beliefs attached to particular stones are not unusual in Ireland, where individual rocks at holy wells, church ruins, and graveyards have long been credited with healing or protective qualities. That this one has been remembered and passed down, even as the physical outline of the site faded from the maps, says something about the persistence of local knowledge where official cartography falls short.
