What is recorded here

Man-made underground passage is a man-made underground passage in Cartronmore, County Sligo, Ireland. The 6.4m structure lies under the removed NE bank of Cartronmore rath, with uncoursed limestone walls, an earth floor and tapering chamber. Limestone slab lintels still roof 1.9m at the WNW end beside a blocked central creep opening.

Located under the bank, on the NE side of Cartronmore rath (SL008-074001-). The Man-made underground passage has been partially exposed where the bank of the rath has been removed. The passage (total L WNW-ESE 6.4m; Wth base 1.3m; Wth top 0.45m; H 0.8m) is walled with un-coursed limestone blocks and partially roofed with limestone slabs. The passage tapers inwards from the floor to the roof. The floor is of earth. The passage is exposed at the ESE end for a length of 5.5m where the lintels have been removed and the side wall lowered (H 0.4m). The roof survives, with the lintels covered with sod, for 1.9m at the WNW end. At the WNW is a vertical end wall with a lintelled creep (Wth 0.3m; H 0.20), now blocked, located centrally at the base of the wall. Compiled by: Patrick F. O'Donovan Date of upload: 21 April 2011
