The Oulu Cathedral is an Evangelical Lutheran cathedral and the seat of the Diocese of Oulu. The church was built in 1777 as a tribute to the King of Sweden Gustav III of Sweden and named after his wife as Sofia Magdalena's church.
The wooden structures burned in the large fire of the city of Oulu in 1822. The church was built again on top of the old stonewalls with famous architect Carl Ludvig Engel as the designer. The restoration works were completed in 1832, but the belfry was not erected until 1845.

The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
