Man-made underground passage in Killiaghan AND Gort

Towards the bottom of a slight E-facing slope in a low-lying landscape. Discovered in 1986 during the improvement of the N 61 Athlone-Roscommon road when the outer chamber was unroofed. It consisted of a corbelled subrectangular chamber (dims c. 3.5m NE-SW; 1.6m NW-SE; H c. 1.6m) with a blocked creep at the S end of the NW wall and an air vent in the SW wall. At the N end of the SE wall a creep (Wth 0.35-0.8m; H 0.6-0.9m; L 1.45m) led to the S end of the NW wall of a second corbelled subrectangular chamber (dims 3.9m NE-SW; 1.6m E-W; H 1.9m) which has an air vent in the S wall and a blocked creep at the N end of the NW wall. This led to a collapsed third chamber. The Man-made underground passage was filled with stones and survives under the road, but is inaccessible.
