Lítla Dímun, Faroe Islands, Norwegian Sea

History
The island has never been inhabited by humans, but sheep were kept there from ancient times, being mentioned in the 13th century work Færeyinga Saga (Saga of the Faroese). The saga also features the island as the site of a battle between Brestur, father of Sigmundur and Gøtuskeggjar. The battle resulted in the death of Sigmund's father and his men and the deportation of Sigmund to Norway, where he befriended Olaf Trygvasson.
