Built in 1899, the old-fashioned department store's flagship location closed its doors in 2007. While shopping—window or otherwise—is no longer an option, it's worth checking out the building's facade. The work of one of Chicago's most renowned architects, it combines Louis H. Sullivan's visionary expression of modern design with intricate cast-iron ornamentation. The eye-catching rotunda and the 11 stories above it are actually an addition Sullivan made to his original building. In later years, D. H. Burnham & Co. and Holabird & Root extended Sullivan's smooth, horizontal scheme farther down State Street.
