The Auditorium Building by Louis Sullivan and Dankmar Adler was designed to be a multi-use complex, including offices, a theater and a hotel. It is both a Chicago and national historic landmark.
This south view captures the use of massive exterior load-bearing masonry walls of granite below and limestone above. The weight of the walls in relation to the relatively lightweight interior deformed its raft foundation during the course of a century, and today portions of the building have settled as much as 29 inches.
