A similar Cahergal legend told of "...an underground passage, supposed to lead through the mountains to Cloc-na-Natin (The Temple of Fire)." (Bean, Kathleen. "Cahergall." Kerry Archaeological Magazine 2 (1912-1914): 155-57.)
According to NUI-Galway archaeologist Michelle Comber, "Most have only one exit/entrance, i.e. are 'dead-ends', not leading anywhere. Some do have an exit, e.g. the souterrain at Leacanabuaile cashel...leads from inside one of its internal houses under the cashel and exits through a hole at the rear of the cashel wall, providing a possible escape route. Souterrains do not, however, run for great lengths, and never connect one monument with another – despite this being a favourite local tale in most parts of Ireland!" (Comber, Michelle.
