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:The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
