Dun Gallain is also called Fort of the Strangers. An old folk tale told locally holds that in the Viking period the fort was the residence of a local chief named Grey Somerled, related to the Lords of the Isles.
This Grey Somerled was betrayed to his enemies, who seized him and imprisoned him in a stone hut at Machrins, a mile or so away. One day a stone fell from the roof of the hut, killing the chief.
