Which cathedral in Norway is traditionally regarded as the world's northernmost medieval cathedral?

Nidaros Cathedral is traditionally regarded as the world's northernmost medieval cathedral.

Located in Trondheim, Norway, the cathedral was built over the burial site of King Olaf II, better known as Saint Olav, who died in 1030. His shrine made Trondheim an important pilgrimage destination during the Middle Ages and helped establish the church as Norway's principal religious centre.

The present building is a large Gothic structure with earlier Romanesque sections. Construction developed over several centuries, and the cathedral has been damaged and restored repeatedly by fire and other disasters. Its western façade is especially recognizable for its rows of statues.

Nidaros Cathedral is still an active church and remains closely associated with Norwegian royal ceremonies. “Northernmost medieval cathedral” is a traditional geographical description; it should not be confused with claims about the northernmost cathedral of any architectural period or denomination.
