Källunge church (Källunge kyrka) is a church in the island-bishopric of Visby on Gotland. The church is richly decorated with reliefs and frescoes. The frescoes are important evidence of the strong Byzantine influence on Swedish art of the 12th and 13th centuries. An early depiction of a nyckelharpa is found in a relief dating from circa 1350 on one of the gates of the church.
The church gives its name to the Källunge codex (Latin Codex Kellungensis) a 1622 collection of choral music by Philipp Dulichius, Melchior Vulpius, Gregor Aichinger, Nicolaus Zangius,Hieronymus Praetorius, Hans Hassler, Jacobus Gallus, Johann Walter, Dominique Phinot, Orlando di Lasso, and Johann Bahr among others. The collection was discovered in 1913, though only the alto part is extant. 100 of the 315 pieces have been identified from other collections.

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.
