Cathedral Ruins in Hamar

Hamar Cathedral was the see of the Ancient Diocese of Hamar. The diocese at Hamar had included much of the counties of Hedmark, Oppland, and Buskerud. The ruins form part of Anno Museum, formerly Hedmark museum, and were selected as the millennium site for Hedmark county.
The cathedral's construction was begun by Bishop Arnaldur , who was appointed first Bishop of Hamar in 1150 on his return from Gardar, Greenland. The cathedral was completed about the time of Bishop Paul . It was originally built in the Romanesque architectural style and later converted to Gothic. Bishop Thorfinn of Hamar was exiled and died at Ter Doest in Flanders. Thorfinn and many other bishops of the area disagreed with King Eric II of Norway regarding a number of issues, including episcopal elections. Bishop Jörund was transferred to Trondheim.
