The city of Chicago has had public art projects for over a century, but things really took off with the passage in 1978 of the Percent for Art Ordinance. This act stipulated that a percentage of construction and renovation costs for municipal buildings and public spaces be set aside for original artwork. This website offers visitors several guides to the more than 700 works of art exhibited in 150 municipal facilities around the city. The curious can find them in CTA stations, police stations, libraries, and City Hall. On the site, visitors can look over the Highlights area for an introduction to some of these fine works. Additionally, the site contains separate maps for five different areas of the city, including the Loop and the near South Side.
