Straßburg Castle fas first time mentioned in 1147. It was built by Roman I, the bishop of Gurk. The chapel was built in the late 12th century, consisting of nave, chancel and apse. In the 14th century, the chapel was raised by one floor, and another floor was erected in the 15th century above the choir. The last modification to to the choir took place in 1682.
In the 14th century, the eastern tower was built on the outside of the northern ring wall. There is a medieval kitchen, still preserved. The western tower (Münzturm) was built in the 15th century.
Today Straßburg castle hosts a folkloristic collection exhibiting objects from rural life of past centuries. The exhibition Women’s Artworks of the Werkmann collection shows unique exhibits from the past 200 years with needlework of rural life, nobility and bourgeoisie.
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.
