Carolina Rediviva is the main building of the
Uppsala University Library in
Uppsala,
Sweden. The building was begun in 1820 and completed in 1841. The original architect was Carl Fredrik Sundvall. Later additions to the building have been designed by
Axel Johan Anderberg and
Peter Celsing. The name, literally "Carolina Revived", was given in remembrance of the old
Academia Carolina building, which had functioned as university library for most of the 18th century (see
Uppsala University Library). Carolina Rediviva is the oldest and largest university library building in the country. It is also the site where the
Codex Argenteus and the
Cancionero de Upsala are kept.
