The open-air museum, created since 1972 thanks to an ambitious policy of public commissions, offers a unique journey in the world in a business district around 76 monumental works. Calder's stabile, Agam's fountain, Miro's figures, are among the first works installed at La Défense, followed by Takis' basin, Moretti's chimney, César's thumb, and most recently Serra's Slat...
