Fužine Castle is Ljubljana's has retained its original Renaissance character. It was built by a crossing point over the Ljubljanica river's rapids between 1528 and 1557 on commission from the wealthy local merchants Veit Khisl and Hans Weilhaimer, the former of whom served several terms of office as Mayor of Ljubljana. A defence tower was built in each of the four corners of the castle building and another one over the entrance, which is accessible via a stone bridge across the moat surrounding the castle. Inside the castle there are remains of Renaissance and Baroque wall paintings, and on the wooden ceiling of the castle chapel a fragment of a ceiling painting.
During its history the castle has housed an iron smelting works, a smithy, a glassworks and a paper pulping mill, and served as ancillary premises of a power plant. Since 1992, when it was thoroughly renovated by the architect Peter Gabrijelčič, it has been occupied by the Museum of Architecture and Design.
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.
