Clonlum South Cairn

Clonlum South Cairn still stands in County Armagh, a low ridge of broken stone that may have marked a boundary, a burial or a warning. People walked past it in rain and darkness for centuries, perhaps dropping a stone or leaving it untouched depending on what they believed. The south-facing gap suggests deliberate placement rather than casual dumping, though no written account survives to confirm the intent.
