Chicago’s year-old Millennium Park has been a great success. “The joyful postindustrial playground, which has brazenly discarded the old industrial age model of the serene urban park, is blowing equally strong winds of change across the cityscape that surrounds it, altering a museum’s plans, boosting real estate prospects and (perhaps) opening doors for more innovative architecture in a city whose design scene had grown stale as recently as a decade ago. It has emerged as a sparkling example, despite its widely publicized delays and cost overruns, of how big cities can get big things done. In the national conversation, Millennium Park is being hailed in some quarters as an example of how business and political leaders can pull together.”
