Calmeyer Street Mission House

The Calmeyer Street Mission House, located in Oslo, Norway, was a significant Gothic Revival building designed by architect Henrik Nissen and completed in 1891. It served as a major venue for Lutheran gatherings, boasting Scandinavia's largest assembly hall at the time, accommodating over 5,000 people. The building was pivotal for large religious events, including revivals in 1905 and 1906, and hosted notable figures such as Prime Minister Christian Michelsen. It was taken over by the Kristiania Home Mission Society in 1898 and became a center for theological debates in 1920. During World War II, it was requisitioned by the German military and later used for concerts and storage until it was demolished in 1972. The site has since been redeveloped into an office building with rental housing, completed in 1987.
