The Riddarholmen Church (Riddarholmskyrkan) is the burial church of the Swedish monarchs. The congregation was dissolved in 1807 and today the church is used only for burial and commemorative purposes. Swedish monarchs from Gustavus Adolphus (d. 1632 AD) to Gustaf V (d. 1950) are entombed here (with exceptions such as Queen Christina who is buried within St. Peter's Basilica in Rome), as well as the earlier monarchs Magnus III (d. 1290) and Charles VIII (d. 1470).
Riddarholmen church is one of the oldest buildings in Stockholm, parts of it dating to the late 13th century, when it was built as a greyfriars monastery. After the Protestant Reformation, the monastery was closed and the building transformed into a Protestant church. A spire designed by Willem Boy was added during the reign of John III, but it was destroyed by a strike of lightning on July 28, 1835 after which it was replaced with the present cast iron spire.
Coats of arms of knights of the Order of the Seraphim are in the walls of the church. When a knight of the Order dies, his coat of arms is hung in the church and when the funeral takes place the church bells are rung constantly from 12:00 to 13:00.
References: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.
