The museum's collections are distributed over five different venues: Santo Domingo Convent, Sarmiento Palace, the Castro Monteagudo building, and the García Flórez and Fernández López buildings.
At the 18th-century Castro Monteagudo building you can see collections of archaeology, traditional and civil pre-Roman and Roman precious metalwork (Fernández de la Mora collection), as well as Spanish, Italian and Flemish painting from the 15th-18th centuries. The García Flórez building dates from the 18th century and is joined to the aforementioned, with items in jet, engravings, religious sculptures, Sargadelos earthenware, the office of Admiral Méndez Núñez, and a reproduction of a chamber from the Numancia Frigate, as well as a traditional Galician kitchen. In the same square as the two buildings already mentioned is the Fernández López building, home to the exhibitions of 19th and 20th-century Spanish painting. Next to San Bartolomé Church is the Sarmiento building (18th century), which is dedicated to contemporary Galician painting and temporary exhibitions. In the ruins of the Santo Domingo Convent you can see diverse archaeological remains, such as Romanesque and Gothic capitals, sarcophagi and tombstones.
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.
