The Adler Planetarium is one of three institutes which together comprise the Museum Campus at the south end of Grant Park. A statue of Copernicus sits outside the planetarium, a conscious reminder that Chicago is the second largest Polish city in the world, thanks to the number of immigrants who came here and continue to come here. The second member of the campus is the large Shedd Aquarium. I haven't been inside the planetarium, the aquarium, or the Art Institute across the park, mostly because none of them offer much in the way of opportunities for photography.
