Structure in Cill Mhuirbhigh

This structure, identified as Structure 5, was revealed during the course of research excavations in the W half of the inner enclosure at Dún Aonghasa (GA110-039----). Only the foundation course (L 3m; H 0.48m) of its NW sector survived and the remains were too incomplete to suggest a ground plan. The surviving wall was of mixed construction with the central part being double-faced (Wth 0.82m) and both ends consisting of single orthostats. No occupation horizon could be unequivocally associated with it. Stratigraphically the structure was later than structure 8b (GA110-039005-) - its S wall had partly truncated the N wall of the latter - and it pre-dated the secondary refurbishment of the wall of the inner enclosure. Structure 2 (GA110-039007-) post-dated it (Cotter 2012, vol. 1, 306-7; 310; vol. 2, 246). Compiled by: Olive Alcock Date of upload: 22 June 2020
