Strängnäs Cathedral is built mainly of bricks in the characteristic Scandinavian Brick Gothic style. The original church was built of wood, probably during the first decades of the 12th century, on a spot where pagan rituals used to take place and where the missionary Saint Eskil was killed during the mid 11th century. The wooden church was not rebuilt in stone and bricks until 1296, just after Strängnäs became a diocese. The cathedral was probably inaugurated by bishop Styrbjörn in 1334.
The oldest murals date from the 14th century. The Strängnäs Cathedral was enlarged in several phases during the 15th century and it was damaged by fire in 1473. Bishop Kort Rogge (1479-1501) donated two crucifixes which are still located in the cathedral. The larger one is made in Brussels around 1490. There are also many other significant medieval artefacts in the cathedral. The cathedral contains also the burials of Charles IX of Sweden and Maria of Palatinate-Simmern.
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.
