Man-made underground passage & ?RATH in Frosses

Under Frosses in County Antrim, a man-made passage and rath wait beneath the soil, their age uncertain but their intent clear. People dug through rock or earth to create a hidden route, perhaps for trade, flight, or worship. The rath above may have marked a home, a fortress, or a sacred boundary. Together they suggest a place where the surface and darkness served the same purpose.
