Written by Jacqui Palumbo, CNN After three months of construction work at Paris' famed Arc de Triomphe, the 160-foot-tall war monument has been completely concealed. The landmark, built during Napoleon's reign, has been outfitted in 270,000 square feet of silver-blue polypropylene fabric bound with red ropes. Encasing the Arc de Triomphe in cloth was a longstanding vision of the late artists Christo and Jeanne-Claude -- one that finally came into focus this summer. It began with 400 tons of steel beams erected like a metal jacket around the structure, followed by the wrapping, which was conducted by a team of climbers over the course of a few days. Following the project's completion on Thursday, the arch will remain transformed for just 16 days.

Originally scheduled for spring 2020, the project was first delayed out of concern for nesting kestrel falcons in the arch, and then because of the ongoing pandemic. Like many of Christo and Jeanne-Claude's other projects, "L'Arc de Triomphe, Wrapped" is poised to be a fleeting, sublime encounter with an environmental artwork that interrupts the experience of the everyday.
