Snizort Cathedral (Gaelic: Snìosort) was a small cathedral church located on an island (St Columba's Isle, Gaelic: Eilean Chaluim Chille) in the River Snizort, near the head of Loch Snizort on the Scottish island of Skye. Also referred to as Church of St Columba or Skeabost, it was founded under the authority of the Archbishop of Nidaros (Trondheim) in Norway. Amongst its more famous bishops was Wimund, who according to William of Newburgh became a seafaring warlord adventurer in the years after 1147".
