Man-made underground passage in Barnacoghil

At a rath (SL018-025001-). On the line of the levelled inner bank of the rath at W is a hollow area (max. dim. 3m). A linear depression (Wth 1.5m; D 0.6m) extends E for 3m from the hollow into the interior. From here it turn S for c. 4m and then extends SE for a further c. 4m. These remains are probably those of a collapsed Man-made underground passage. Compiled by: Patrick F. O'Donovan Date of upload: 19 January 2011
