This imposing steel sculpture (called a stabile by its creator, as opposed to its mobiles) weighs 75 tonnes and is 15 metres high. It evokes a famous work by the same artist, Flamingo, located in Chicago.

Installed in 1976, the year of the artist's death, who himself chose its location on the Place de La Défense, it now resonates as a powerful tribute to its creator.

Born in Philadelphia in 1898, Alexander Calder was both a sculptor and a painter. For many years, he was fascinated by the theme of the circus, and even drew inspiration from it for a now-famous performance: the Calder Circus.

He had the genius to transform sheet metal into a work of art and a tin can into a bird. He bridged the gap between surrealism, abstract art and some of the most modern research, for which he was an avant-garde figure.
