The church underwent several renovations during the 20th century. Between 1921–1923 major changes were done to the interior. During those years new stained glass windows designed by Emanuel Vigeland were added. The work was led under the direction of architect Lars Israel Wahlman. He had previously designed the Engelbrekt Church. Between 1954–1956 additional changes were made to the church interior. During those years the altarpiece was changed and some ornamental ceiling decorations were removed.
