# Roman Catholic Diocese of Skálholt

The Roman Catholic Diocese of Skálholt has been a titular see of the Catholic Church since 1968. It was the estate of the first bishop in Iceland, Isleifr Gizurarson, who became bishop in 1056. Christianity had been formally adopted in 1000. His son, Gizurr, donated it to become the official see of the Diocese. It ceased its functions as a Roman Catholic diocese with the Reformation.
