Saint Magnus Cathedral

St Magnus Cathedral dominates the skyline of Kirkwall, the main town of Orkney, a group of islands off the north coast of mainland Scotland. It is the oldest cathedral in Scotland, and the most northerly cathedral in the United Kingdom, a fine example of Romanesque architecture built for the bishops of Orkney when the islands were ruled by the Norse Earls of Orkney. It is owned not by the church, but by the burgh of Kirkwall as a result of an act of King James III of Scotland following Orkney's annexation by the Scottish Crown in 1468. It has its own dungeon.

Construction began in 1137, and it was added to over the next 300 years. The first bishop was William the Old, and the diocese was under the authority of the Archbishop of Nidaros in Norway. It was for Bishop William that the nearby Bishop's Palace was built.
