The restoration work
In 1869 the restoration of the Chapter House started. The main idea was to restore the cathedral back to its former appearance, and remove all newer additions. There were on the other hand no agreement on how the cathedral looked like during the Middle Ages.
In the 1870’s the restoration of the octagon and chancel started, and soon after the tower and transept. This work was finished in the beginning of the 20th century, and in 1905 the reconstruction of the nave and western façade started. The nave was finished in 1930, and the façade in the 1980’s. It was not until 2001, however, that the last vault in the western towers were finished.
