Located in the Tuileries Garden, since 1984 the museum has been home to the Jean Walter and Paul Guillaume collection, which has been sold to the state on very generous terms. This collection includes 144 paintings from the late nineteenth and the first half of the twentieth century (Cezanne, Renoir, Matisse, Picasso, Derain, Soutine, Modigliani, Utrillo, Douanier Rousseau ...). It joined the eight immense compositions of Water Lilies that Monet offered to France in 1922 and which have been installed since 1927 in two large oval rooms specially fitted out in the building, on the indications of the painter to receive them.
