Environmental artists Christo and his wife, Jean-Claude, created “The Gates” as a study for their huge 2005 installation project in New York’s Central park. On view for 16 days, the project featured saffron-colored fabric draped over 7,500 16-feet tall gateways along 23 miles of park walkways. “The Gates” represent openings in the park’s stone wall that were originally designed to enclose steel gates when the park was built. “The Gates,” a fluid vision of an immense accomplishment, can stand on its own as evocative art.
