Chicago - The Loop

Chicago's financial and business district is known as the Loop: in the strict sense only the area enclosed by the "El" (elevated railway), but in practice taking in a dozen or so blocks on both sides of the Chicago River. The El follows Wabash Street, Lake Street, Wells Street and Van Buren Street, on which are many buildings designed by great architects. On the squares and in the public buildings of the Loop there are over 60 works by well-known artists, including Picasso, Chagall and Alexander Calder.
