Man-made underground passage in Drumharsna South

Within the interior of a cashel (GA113-112----). A stone-filled hollow noted in the W half of the cashel, when initially visited by the Survey in October 1982, may have marked the site of a possible Man-made underground passage recorded by McCaffrey (1952, 271, no. 30). On a revisit in August 1985 it was found that the cashel had been levelled and no visible surface trace of it or hollow survived.
