Laval Cathedral (Cathédrale de la Sainte-Trinité de Laval) was founded around 1070, but the current exterior dates mainly from 1855 when it was promoted as a cathedral. The cathedral has been enlarged several times during centuries. There were originally dozen altarpieces, but only one survived from the French Revolution. It was built in the 17th century. The pulpit was made in 1803 and marble font in 1554.
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.
