Man-made underground passage in Carnakit

At the crest of the N-facing slope of a WNW-ESE ridge, in the interior of rath (RO021-042043-). A collapsed Man-made underground passage is visible as a group of interconnected hollows with stones from the side-walls occasionally visible. An oval hollow (dims 8m E-W; 5m N-S; D 0.8m) close to the centre of the rath has a rectangular hollow (dims 7m N-S; 4m E-W; D 0.5m) running S from its centre with a constriction at its S end. This constriction leads into the E end of a hollow (dims 10m E-W; 3.5m N-S; D 0.4m) which has an oval hollow (dims 5.6m N-S; 4.3m E-W; max. D 0.7-1m) attached to the N side of its W end.
