Auditorium Building, Chicago, IL., under construction (1888)

The Auditorium Building in Chicago is one of the best-known designs of Louis Sullivan and Dankmar Adler.

Completed in 1889, the building is located at the northwest corner of South Michigan Avenue and Congress Street (now Congress Parkway). The building, which when constructed was the largest in the United States and the tallest in Chicago, was designed to be a multi-use complex, including offices, a theater and a hotel. As a young apprentice, Frank Lloyd Wright worked on some of the interior design.

The building was added to the National Register of Historic Places on April 17, 1970. It was declared a National Historic Landmark in 1975, and was designated a Chicago Landmark on September 15, 1976. In addition, it is a historic district contributing property for the Chicago Landmark Historic Michigan Boulevard District. Since 1947, the Auditorium Building has been part of Roosevelt University.
