Jämtland was Christianized in the middle of the 11th century when the Frösö Runestone appeared (the only one in the world that tells about the christening of a country), shortly after Olaf II of Norway died in the Battle of Stiklestad just west of Jämtland. During this period Jämtland turned into a Christian region and the first church, Västerhus chapel was built shortly after the runestone appeared.
