Christo, who with his partner Jeanne-Claude used sculpture as a means to dramatically shift people’s understanding of iconic structures and sites, has died at 84. According to a press release put out by the artist’s office, Christo died on May 31 of natural causes.

“Christo lived his life to the fullest, not only dreaming up what seemed impossible but realizing it,” the artist’s office said in a statement. “Christo and Jeanne-Claude’s artwork brought people together in shared experiences across the globe, and their work lives on in our hearts and memories.”
