RATH & possible Man-made underground passage in Ballyaughian

Ballyaughian holds a rath and a possible man-made underground passage, recorded for the common era in County Down. The boundary between built structure and natural earth blunts because no exact chamber, entrance or date has survived. A family may have cut the passage during storms or hidden bread from strangers, but invention must stop where evidence ends. What remains certain is that people shaped the land enough for the passage to still be debated.
