Grefsen Church is a long church (Norwegian: langkirke) located in Grefsen, a neighborhood of Oslo, Norway.
The church was consecrated by Bishop Eivind Berggrav on March 3, 1940[2][3] and it is the parish church of the Grefsen Parish. It is built of brick, has a frescoed ceiling, and can accommodate 600 people. It was designed by the architect Georg Greve.[1] The building has elements of the Norwegian Romanesque style, but has rectangular window openings instead of Romanesque arches. It is sparsely decorated.[1] The stained glass in the chancel was created by Oddmund Kristiansen.[2] Grefsen Church has protected status as a church listed by the Norwegian Directorate for Cultural Heritage. Magne Elvestrand served as organist at the church from 1940 to 1967.[4]
