Man-made underground passage in Ballinderreen

Within the SW quadrant of a rath (GA103-008----). This drystone-built rectangular passage (L 5m; Wth 1.8m) runs NW-SE. Access is gained via a small gap at the NW end and a considerable amount of collapse is evident at both ends. According to the landowner, the passage extended roughly 11m further to the ENE, from the SE end. A large grassed-over flagstone at this point may be a roof lintel.
