Kolbeinn hrúga
Kolbeinn hrúga was a 12th century Norse chieftain in Orkney. He figures prominently in the Orkneyinga saga. Kolbeinn was born in Sunnfjord, Norway. Around 1145, he arrived in Orkney. Shortly after his arrival, Kolbeinn was responsible for constructing numerous castles on the west side of the island of Wyre, which are some of the oldest of its kind in Orkney. The influence of Kolbeinn is attested by his contribution to elevating Eystein II to King of Norway.
