Chicago
Chicago, located in northeastern Illinois on the southwestern shore of Lake Michigan, is the third-largest city in the USA with around 2.7 million inhabitants. You come primarily for its architecture: After the Great Fire of 1871, the Home Insurance Building, considered the first modern skyscraper, was built here in 1885.The city center is called the Loop, named after the elevated train that circles the business district. In the Willis Tower, you stand on the glass balcony The Ledge on the 103rd floor, about 412 m above the street. The Millennium Park, opened in 2004, features Anish Kapoor's sculpture Cloud Gate, and the Art Institute of Chicago mainly displays Impressionism and American art.The architecture tour by the Chicago Architecture Center on the Chicago River lasts around 90 minutes and passes more than 50 buildings. From O'Hare Airport, the Blue Line runs 24/7, taking 40 to 45 minutes to reach downtown.
