Man-made underground passage in Creggymulgreny

In the W half of a cashel (GA104-124----). McCaffrey (1952, 228, no. 89a) noted a 'depression in the ground', which he labelled 'Sout.' on his accompanying sketch plan of the cashel. No visible surface trace survives but an irregular pile of field-clearance rubble marks its site. Two large limestone slabs protruding from the rubble may be from the Man-made underground passage.
