The Cathedral, Basarene and Brannvakten are all built in red brick. Both Basarene and Brannvakten were built between the years 1840-1859 from the plans of City Architect, Christian H. Grosch. Art works from recent times in the cathedral include stained glass windows in the choir by Emanuel Vigeland installed between 1910–16, west portal's bronze doors executed by Dagfin Werenskiold (1892-1977) in 1938, and the silver sculpture with communion scene by Italian sculptor Arrigo Minerbi dating from 1930. The ceiling decorations are by Norwegian painter Hugo Lous Mohr (1889-1970). In the latter half of the 1990s, the main organ built by Ryde & Berg of Fredrikstad, was mounted behind the old baroque facade. Restoration was completed at the time of the city's 900 anniversary in 1950. The church was restored under the plans of architect Arnstein Arneberg. The neo-Gothic interior was removed and the original furnishings brought back. Arneberg also designed the chapel on the south side of the church. The church was closed in August 2006 for renovation and was opened in April 2010 in the presence of Harald V of Norway and the Norwegian royal family.
