The history of Nidaros Cathedral - step by step
Medieval cathedrals were the largest construction projects of their day, and building them took many years. Generations of craftsmen and artisans spent their whole lives working on the Cathedral without ever seeing it completed. For more than 450 years work was going on somewhere on the Cathedral. Here you can trace the more than 900 years of the Cathedral's history.

Around 1035
The Cathedral's High Altar stands on the spot where ancient tradition has it that St. Olav lay secretly buried for a year following his death at the Battle of Stiklestad on 29 July 1030. A small wooden chapel was built over the original burial site shortly after Olav was declared a saint in 1031.
Around 1090
Between 1070 and 1090 this small wooden chapel was replaced by the first stone cathedral, built by King Olav the Gentle, nephew of the saint. The church was dedicated to the Holy Trinity and was commonly known as Christchurch. Christchurch was the largest church in the country at the time, and was probably built by English craftsmen.
Second half of the 12th century
In 1151/53 Norway was elevated from the status of a bishopric and Nidaros became the see at the centre of a large Norwegian archbishopric. Nidaros was chosen in large part due to the enormous popularity of St. Olav and the stream of pilgrims flocking to his shrine which was placed above the high altar of Christchurch. The two first archbishops, Jon and Øystein, initiated a major construction programme to enlarge Christchurch. The new sections were built in the Anglo-Norman Romanesque style and many of the craftsmen were undoubtedly English, probably from Lincoln. The transepts, the Chapter House and a small portion of the nave were completed before construction work was stopped when Archbishop Øystein was forced into exile in England in 1180.
Around 1220
During his three years in England the Archbishop learned about new architectural trends. On his return in 1183 the building programme was revised. Construction on a new eight-sided presbytery, an octagon with a raised middle section, was started above the saint's shrine. The octagon is more ornately decorated than the older parts of the building. The style is Early Gothic, and the ornamentation suggests that the craftsmen came from western France, which was under the English Crown at the time.
Around 1240
The octagon was completed about 1210-20, and work then commenced on the construction of a new chancel replacing the remaining part of Olav the Gentle's Christchurch. Completed in the 1240s, this was the largest structure that had been built in Norway. Built in Early English Gothic style, the chancel was sparsely furnished with sculptures comparable to the octagon.
Around 1300
Plans had been in the works for many decades to extend the nave toward the west, and some work had actually been started on it. When the chancel was completed, construction work was resumed on the nave. Archbishop Sigurd laid the foundation stone for the West Front in 1248. The western facade, flanked with two towers, formed a continuous screening wall incorporating three rows of sculptures. The nave also imitated English styles, particularly from Lincoln Cathedral and Westminster Abbey. Nonetheless, the statues on the West Front clearly reveal a French influence, particularly from the sculptures on the Reims Cathedral. The nave was probably finished around 1300.

Around 1550
In 1328 the Cathedral was badly damaged by a fire in which the entire wooden structure in the roof and the internal wooden fixtures were destroyed. Major renovation work was then undertaken, particularly in the octagon. Christchurch burned again in 1432 and perhaps also in 1451. As the church was by no means rich, only the most necessary repairs were carried out. In 1531 a fire ravaged the entire town of Trondheim, including the Cathedral, and the damage was so extensive that drastic measures were required. However, the Reformation was imminent, and the church's income was greatly diminished. Thus only the chancel was rebuilt, albeit quite modestly, and the large nave was left in ruins.

1708 - 1869
In 1708 the Cathedral burned down leaving only the walls standing. Rebuilding had hardly been completed before the church was once again ravaged by fire after being struck by lightning in 1719. The rebuilding work was by no means extravagant, with only a pyramidal roof capping the central tower, and a Baroque onion dome capping the Octagon. The old medieval chapels were made into burial chapels for well-off citizens.

1869 - 1969
The national awareness that had been growing throughout the 19th century brought with it the desire to rebuild the Cathedral in Trondheim to its former medieval glory. This sentiment gained acceptance, and restoration started in 1869. Construction work was only initiated after years of collection and involved painstaking reconstruction of the Cathedral's original Medieval elements. Skilled artisans and artists were assembled, and we can see their accomplishments today. When the West Front was rebuilt, the restoration of most of the Cathedral reached completion in 1969. The last statue was put in place in 1983.
