The Loop is the central business district of Chicago. As a business center, the Loop hosts the Chicago Board of Trade at the foot of LaSalle Street, the Chicago Mercantile Exchange and the Chicago Board Options Exchange. The Loop is home to Grant Park, the State Street shopping district, and the Art Institute of Chicago. Other major cultural institutions that call this area home include the Chicago Symphony Orchestra, the Lyric Opera of Chicago, the Goodman Theatre, the Joffrey Ballet, the central public Harold Washington Library, and the Chicago Cultural Center.
Chicago has a famous skyline which features many of the tallest buildings in the world as well as the Chicago Landmark Historic Michigan Boulevard District. Chicago’s skyline is spaced out throughout the downtown area, giving it a graceful bridgelike appearance. The Willis Tower, formerly known as the Sears Tower, the second tallest building in the Western Hemisphere, stands in the western Loop in the heart of the city’s financial district.
