The art gallery was opened in 1951 by Solomon R. Guggenheim and hosts the private collection of his wife Peggy, one of the most influent personalities in XX century art. The works of her collection are shown together with other paintings from private collections (in 2012 the musuem received more than 80 works from the Schuholf Collection) or from temporary exhibitions.

It hosts works by Picasso, de Chirico, Mondrian, Kandinsky, Miró, Klee, Ernst, Magritte, Dalí e Pollock and by many others in the areas of Dadaism, Cubism, Futurism and Surrealism.
In the evocative garden is presented a rich selection of modern art sculptures.
