There are twenty duns, or ancient forts, in Tiree, it is said, but I have only seen eight, and examined two [..]. These duns, in the popular imagination, are all connected with Ossian’s heroes, and I have had some difficulty in convincing the people that I am not in search of gold. There is a rhyme which says that Fionn left his gold in Dun Shiatar, which is situated near Hynish.
