Chicago, Italy
This giant Gothic church is named for the University founder, John D. Rockefeller, who intended it to be the "central and dominant feature" of the University. It may not be that, but it is impressive, with a huge organ and the second largest carillon in the world. A great way to view the chapel and
experience its acoustics is by showing up for one of the Wednesday lunchtime organ concerts.
