Which museum has housed the triptych oil painting "The Garden of Earthly Delights" since 1939?

"The Garden of Earthly Delights" is the modern title given to a triptych oil painting on oak panel painted by the Early Netherlandish master Hieronymus Bosch, between 1490 and 1510, when Bosch was between 40 and 60 years old. It has been housed in the Museo del Prado in Madrid, Spain since 1939.

As little is known of Bosch's life or intentions, interpretations of his artistic intent behind the work range from an admonition of worldly fleshy indulgence, to a dire warning on the perils of life's temptations, to an evocation of ultimate sexual joy. The intricacy of its symbolism, particularly that of the central panel, has led to a wide range of scholarly interpretations over the centuries. Twentieth-century art historians are divided as to whether the triptych's central panel is a moral warning or a panorama of paradise lost.

The Prado Museum, officially known as Museo Nacional del Prado, is the main Spanish national art museum, located in central Madrid. It houses collections of European art, dating from the 12th century to the early 20th century, based on the former Spanish royal collection, and the single best collection of Spanish art. It also contains important collections of other types of works. The numerous works by Francisco Goya, the single most extensively represented artist, as well as by Hieronymus Bosch, El Greco, Peter Paul Rubens, Titian, and Diego Velázquez, are some of the highlights of the collection.
