What is recorded here

Man-made underground passage is a man-made underground passage in Sheegeeragh, County Roscommon, Ireland. It appears only on the 1930 edition of the OS 6-inch map, described in gothic lettering at the southeast edge of a rath. The structure measures 3.25 metres long, 1.7 metres wide and 1.7 metres high, aligned east-northeast to west-southwest with a blocked entrance at the east end. A separate excavation at the southeast end provides the present entrance, while the east-end creep suggests another outer chamber or passage.

Marked only on the 1930 ed. of the OS 6-inch map where it is described in gothic lettering as a 'Man-made underground passage'. It is located at the SE edge of rath (RO028-136001-). This is an undifferentiated corbelled and lintelled passage (L 3.25m; Wth 1.7m; max. H 1.7m) aligned ENE-WSW with a blocked entrance (Wth 0.6m; H 0.55m) to a creep at the E end. The present entrance is by an excavation from the SE end of Man-made underground passage (RO028-136002-), but the creep at the E end suggests that it has another, outer chamber/ passage. The W wall of the chamber has an air-vent (dims 0.4m x 0.25m; L 2m). Compiled by: Michael Moore Date of revised upload: 5 November 2018
