The Musee Picasso is an art gallery located in the Hotel Sale in rue de Thorigny, in the Marais district of Paris. The mansion has changed hands several times through both sales and inheritances. The occupants have included the Embassy of the Republic of Venice (1671), then Francois de Neufville, duc de Villeroi; it was expropriated by the State during the Revolution; in 1815 it became a school, in which Balzac studied. Picasso once said "I am the greatest collector of Picassos in the world." He had amassed an enormous collection of his own work by the time of his death in 1973, ranging from sketchbooks to finished masterpieces. The Musee Picasso contains more than 3000 different works of art by Pablo Picasso including drawings, ceramics and paintings. This is complemented by Picasso's own personal art collection of works by other artists, including Cezanne, Degas, Rousseau, Seurat, de Chirico and Matisse.
