The Art Institute of Chicago on South Michigan Avenue in Grant Park occupies a building designed in 1893 by Shepley, Rutan and Coolidge of Boston. It was built as the World's Congress Auxiliary Building and completed for the fair's second year, and the Art Institute was to occupy it afterward. The article names no start date. The institute moved in on October 31, 1893.

The Modern Wing opened on May 16, 2009 and covers 264,000 square feet (24,500 m²). The museum's total footprint is nearly one million square feet.
The bronze lions were unveiled on May 10, 1894. The institution includes an art museum, libraries and a school. The article gives no hours or ticket details, and it names no client beyond the plan that the institute would take over the building.
