This theater is known the world over for its classic, "Chicago School" design and its acoustically perfect interior. Construction of this landmark began in 1887. It is one of the last remaining buildings in the city designed by the firm of Sullivan and Adler. Along with his partner Dankmar Adler, Sullivan invented the Chicago school of architecture, one that put "form over function" and replaced traditional neoclassical design with a uniquely American flavor. Fully restored to its original luster about 15 years ago, the theatre housed such stage spectaculars as "Les Miserables" and "Phantom of the Opera." Even if there is no show, it is worth a visit to view the beautiful interior. Join one of the tours offered by the Auditorium Theater Association. Admission to performances varies according to seating and show. Tickets range from USD10 to USD75. Hours vary with performances.
