The Thyssen-Bornemisza Museum is an art museum in Madrid, located near the Prado Museum on one of city's main boulevards. It is known as part of the 'Golden Triangle of Art', which also includes the Prado and the Reina Sofia national galleries. The Thyssen-Bornemisza fills the historical gaps in its counterparts' collections: in the Prado's case this includes Italian primitives and works from the English, Dutch and German schools, while in the case of the Reina Sofia it concerns Impressionists, Expressionists, and European and American paintings from the 20th century.
The collection was started in the 1920s as a private collection by Heinrich, Baron Thyssen-Bornemisza de Kászon. In a reversal of the movement of European paintings to the US during this period, one of the elder Baron's sources was the collections of American millionaires coping with the Great Depression and inheritance taxes. In this way he acquired old master paintings such as Ghirlandaio's portrait of Giovanna Tornabuoni and Carpaccio's Knight. The collection was later expanded by Heinrich's son Baron Hans Heinrich Thyssen-Bornemisza (1921–2002), who assembled most of the works from his relatives' collections and proceeded to acquire large numbers of new works (from Gothic art to Lucien Freud).
The Thyssen-Bornemisza Museum officially opened in 1992.
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.
