Millennium Park is a public park located in the Chicago Loop community area of Chicago within Cook County, Illinois, United States. It is a prominent civic center of the city's Lake Michigan lakefront. Completed in 2004, it covers a 24.5-acre (99,000 m2) section of northern Grant Park, previously occupied by Illinois Central railyards and parking lots. The park, which is bounded by Michigan Avenue, Randolph Street, Columbus Drive and East Monroe Drive, features a variety of public art. Today, Millennium Park trails only Navy Pier as a Chicago tourist attraction.
