For this work, the artist chose to follow the contours of the crater, a major thoroughfare for users of the La Défense site, drawing a 30.56 m circle just above it. At regular intervals, sixteen 10 m-high galvanized steel masts are installed, topped by stainless steel weather vanes and multicolored windsocks made of polyester fabric with alternating white and colored 8.7 cm vertical stripes. These gigantic windsocks, over four meters long, rotate continuously, following the direction of the wind, the predominant element on the esplanade. At dusk, they are transformed into luminous works of art by LEDs placed inside the cones.

Daniel Buren studied at the École des Métiers d'Art and the École Nationale Supérieure des Beaux-Arts. He has experimented with painting, sculpture and film. Throughout the world, he has produced hundreds of site-specific works that invade space to reveal its spatial, institutional and aesthetic limits. Each of Buren's creations renews the relationship between work, place and viewer.
