Designed by Pritzker Prize–winning architect Renzo Piano, the Modern Wing provides a new home for the museum’s collection of 20th- and 21st-century art. Now a decade in the making, this 264,000 square-foot building makes the Art Institute the second largest art museum in the United States. The building houses the museum’s world-renowned collections of modern European painting and sculpture, contemporary art, architecture and design, and photography. The extraordinary scope and quality of these collections are a revelation; each displayed more comprehensively than ever before. The Modern Wing allows the Art Institute to take its rightful place as one of the world’s great collections of modern and contemporary art.
