Tiffany Dome

This massive stained-glass masterpiece is thought to be the largest Tiffany dome in existence. In the architectural wonder that is the Chicago Cultural Center, to see what is arguably the most magnificent Tiffany dome ever created, all you have to do is look up. The center’s Preston Bradley Hall is home to a 38-foot-diameter dome that is touted as the largest of its kind in the world—and with 1,134 square feet of colorful mosaics, including 30,000 individual panes of glass, the boast seems valid.
