The Thyssen-Bornemisza Museum

Paseo del Prado, 8, Madrid, Spain
The Thyssen-Bornemisza Collection is one of the most important private collections of paintings of the 20th century and its history is a fascinating one. Although originally a private collection, today it belongs to the Spanish public after its acquisition by the government in 1993, just a year after the museum was opened. In 2004 a significant part of the Carmen Thyssen-Bornemisza Collection was added to it; a collection of over two hundred works that add to the examples of artistic styles and genres of the permanent collection.
