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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
