Nidaros Cathedral (Norwegian: Nidarosdomen / Nidaros Domkirke) is a Church of Norway cathedral located in the city of Trondheim in Trøndelag county. It was built over the burial site of King Olav II (c. 995–1030, reigned 1015–1028), who became the patron saint of the nation, and is the traditional location for the consecration of new kings of Norway. 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.
