Catholic Church in the Faroe Islands
The Catholic Church in the Faroe Islands (Faroese: Katólska Kirkjan í Føroyum) goes back to the year 999, when king Olav Tryggvason of Norway sent Sigmundur Brestisson on a mission to the islands with several priests. The islands became an independent diocese in 1111, but were officially reformed in 1537 and the last Catholic bishop was executed in 1538.
