Nidaros Cathedral in Trondheim became the site of Olaf Nordhagen’s most significant professional engagement when he assumed responsibility for its restoration in 1906. This complex project occupied him for nearly two decades, defining his career until his death in 1925 at the age of forty-two and cementing his influence on Norwegian architectural practices.
Professional Formation and Early Career
Born in Christiania in 1883 to artist Johan Nordhagen and Christine Magdalene Brochmann Johansen, Olaf Nordhagen pursued technical and artistic training. He completed his engineering studies at the Christiania tekniske skole before moving to Denmark. There, he attended the Royal Danish Academy of Fine Arts while assisting Martin Nyrop on the Copenhagen City Hall project. Upon returning to Oslo in 1906, he began his career with smaller commissions, eventually securing a breakthrough with the design of the Bergen Public Library. This building, rendered in the Art Nouveau or Jugendstil aesthetic, earned him the Houen Fund prize.

Nordhagen balanced his architectural pursuits with structural engineering, contributing to the development of Norway's industrial infrastructure. He designed multiple power stations and transformer facilities, including the Såheim Hydroelectric Power Station in Rjukan, working alongside Thorvald Astrup. His other significant power station projects included sites in Tinn, Notodden, Meløy, and Verran municipalities. Beyond practical building, he focused on academic research into traditional Norwegian architectural forms. He formalized this interest through his appointment as a professor at the Norwegian Institute of Technology in Trondheim starting in 1913.
The Nidaros Restoration Controversy
The restoration of Nidaros Cathedral presented a long-term challenge after the passing of architect Christian Christie. Nordhagen took over the leadership of the restoration efforts, a role he maintained for nineteen years. His methodology involved reinterpreting Gothic design elements rather than pursuing a strict, historically faithful reproduction of the original structure. While this interpretive approach generated notable controversy among his contemporaries, he continued the work according to his vision until he died in 1925.
