Man-made underground passage in Rathmichael

The site lies on the E slopes of Carrickgollogan. The OS Letters (1837) refer to an underground passage to the NW of Rathmichael Church (DU026-050001-) (O'Flanagan 1927, 40). It is described as having stone sides and being covered with large flagstones. O'Brien (1988) has suggested a location c. 30m NW of the church where a wide trench (now covered) can be traced for a distance (L 7m) extending towards the cashel wall.
