Nidaros Cathedral

Nidaros Cathedral (Norwegian: Nidarosdomen / Nidaros domkirke) is a Church of Norway cathedral located in the city of Trondheim in Trøndelag county. It is built over the burial site of King Olav II (c. 995–1030, reigned 1015–1028), who brought Christianity to Norway and became the patron saint of the nation; the consecration of new Norwegian monarchs occurs at Nidaros Cathedral. It was built over a 230-year period, from 1070 to 1300 when it was substantially completed. However additional work, additions and renovations have continued intermittently since then, including a major reconstruction starting in 1869 and completed in 2001. Nidaros Cathedral is a popular place of Evangelical-Lutheran Christian pilgrimage, with several thousand pilgrims visiting it each year. Mass and the Divine Office, according to the Evangelical-Lutheran tradition, are celebrated daily at Nidaros Cathedral, in addition to other prayer services that are held there throughout the day.

In 1152, the church was designated as the cathedral for the Roman Catholic Archdiocese of Nidaros. In 1537, during the Protestant Reformation, it became part of the newly established state Church of Norway (Evangelical-Lutheran). It is the northernmost medieval cathedral in the world.
