Calmeyer Street Mission House

[1][2] Calmeyer Street Mission House was a Gothic Revival structure designed by the architect Henrik Nissen.

[3] Educator and businessman Otto Treider was largely responsible for the mission house being built in 1891.

[4] At the time, it contained Scandinavia's largest assembly hall, capable of accommodating over 5,000 people.

[7] The building was also the location of the Calmeyer Street Meeting (Calmeyergatemøtet) from February 15th to 18th, 1920 during debates between liberal and orthodox theologians within the Church of Norway.

After the new building was completed in 1987, the office space was leased to Norwegian Board of Health Supervision (Statens helsetilsyn).
