Man-made underground passage in Barnaderg North

Man-made underground passage

What is recorded here

One chamber and one passage, angled like a broken knee, lie open in the centre of the ringfort. The longer part may have been a room whose stones were taken; the narrower part may have led somewhere before it stopped. Local story says a tunnel ran east to Barnaderg Castle, but the visible hole ends in soil and silence. What is missing is the interesting part: a doorway, a route, a reason for building under a fort.
In the centre of a ringfort (GA044-020----) on the level summit of the hillock on which it sits. It consists of an L-shaped hollow (L c. 12m), up to 1.25m in depth, with traces of the upper courses of drystone walls protruding from the sod along its sides. The longer arm (L c. 7.5m, Wth 4.75), running NW-SE, possibly represents a robbed chamber. Extending off it at a right angle from its NW end is the shorter arm (L 4.5m, Wth 1.2m) which follows a SW-NE course before ceasing abruptly; possibly a passage. Its continuation may, however, be visible 7.4m downslope to NE where a slight stone-lined hollow (L 6.1m, Wth 1.5m) is visible, running E-W. There is a local tradition of a 'tunnel' running from this ringfort to Barnaderg Castle (GA044-018----), 625m to E. The above description is derived from the published 'Archaeological Inventory of County Galway Vol. II - North Galway'.
