The Directorate for Cultural Heritage (Riksantikvaren) and Hedmark Museum invited in 1987 architects to participate in an architectural competition for "a protective building for Hamar Domkirke ruins". 52 entries were submitted and the winners were Kjell Lund and Nils Slaatto Architects. Building started ten years later and the building was opened in August 1998.
"In Hamardomen, the message of medieval piety and mystery is linked to our times recognition and scientific research. In the tension between technical construction and sacred space, the protection building postulates its justification "- architect Kjell Lund.
The glass building is built over the ruin of Hamar cathedral to secure it for posterity. In this way, Hamardomen has outstanding opportunities to combine both the dissemination and use of ecclesiastical acts as well as concerts and theater performances.
The building has a surface area of more than 2600 sqm where steel structures carry a total of 4800 sqm glass area.
