evidence: 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. [...] The unveiling of the installation, officially titled "L’Arc de Triomphe, Wrapped," comes 60 years after Christo first became enthralled with the idea of wrapping the monument, more than a decade after Jeanne-Claude’s death and over a year since Christo passed away last May. 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.
