The Earl's Palace apparently has its place in history having been built for the Scottish nobility when they colonised the Orkney Islands in the 16th century.  The Earl's Palace and the Bishop's Palace stand directly opposite the St Magnus Cathedral which in contrast was built during the Norse rule of the islands.  The cathedral is unique in not being owned by any church but by the people of Orkney and should be a "must see" on any visit to Orkney as a piece of positive inspiration unlike the dark side of the palaces which were allegedly built by local slave labour.
