"[The Museo Thyssen-Bornemisza] is known as a part of the "Golden Triangle of Art", which also includes the Prado and the Reina Sofia galleries. The Thyssen-Bornemisza fills the historical gaps in its counterparts' collections: in the Prado's case this includes fine examples of Italian primitives and works from the English, Dutch and German schools, while in the case of the Reina Sofia the Thyssen-Bornemisza collection includes impressionists, expressionists, and European and American paintings from the second half of the 20th century."
