The Thyssen-Bornemisza Museum is a gallery of ancient art and twentieth century located in Madrid (Spain). Its existence is due to the lease agreement (1988) and subsequent acquisition by the Spanish Government (July 1993), a wide selection of private collection assembled by the Thyssen-Bornemisza family over seven decades. This artistic background gave away many foreign authors of Spanish museum circuit, from the Gothic (Duccio, Jan van Eyck) to pop art and the years 80 (Tom Wesselmann, Lucian Freud), so it came to complement the two main museums state, the Prado and Reina Sofia. Opened in 1992, the Museo Thyssen-Bornemisza settled for one called Art Triangle, perhaps the largest concentration of European painting.
The institution, run by a foundation under public control, is located in a historic building, the Palacio de Villahermosa, which has more than 700 works. Thanks to an annex added later expanded its exhibition with some 300 pieces lent by the Carmen Thyssen-Bornemisza Collection, it also maintains some 60 own deposited in Barcelona MNAC. In the medium term, the foundation will contribute to the management of two museums, in Malaga and Sant Feliu de Guixols (Gerona), created with other works belonging to the said widow of Baron Thyssen.
