I’ve seen Christo’s drawings of this for years - so good to finally see images of this project being realized. In the link (below) there is a photomontage (sketch) of an early wrapping idea in 1962.
The Arc is covered by 25,000 sq metres of silvery fabric, secured by 3,000 metres of red rope and fulfills one of the many life-long proposals of Christo & Jeanne-Claude, who were best known for large-scale wrappings and other massive site-specific artistic interventions.
Lots more excellent images/information here.
