St Magnus Church is a ruined medieval round-tower church located on the island of Egilsay, in Orkney, Scotland. The site is recognized as the place of execution of Saint Magnus Erlendsson, Earl of Orkney, in the 12th century. The roofless structure dates back to the 12th century, and has been described by Historic Environment Scotland (HES) as second only to St Magnus Cathedral, Kirkwall, as a surviving Norse church in Scotland.[1]
