Some stunning public art adorns downtown Chicago, created by world-renowned artists such as Pablo Picasso, Joan Miro, Alexander Calder, Marc Chagall, Henry Moore, and David Smith. Numerous walking tours of the Loop are available, with the Chicago Loop Alliance offering some free tours. Exploring the Loop includes visits to some of the city's best-known works of art, including the Art Institute of Chicago, Millennium Park, the Aon Center Plaza, Thompson Center, Daley Center, Chase Plaza, Federal Plaza, the Chicago Board of Trade Building, and Sears Tower. Joining a tour is a great way to see the most scenic parts of the downtown Chicago Loop, although it is also fun to take a map and find your own way to the main artistic landmarks.
