Fodor's Expert Review Auditorium Theatre of Roosevelt University

Designed by notable architects Louis Sullivan and Dankmar Adler, the 4,300-seat, Romanesque Revival–style Auditorium Theatre of Roosevelt University opened in 1899 as an opera house and later became a National Historic Landmark. Known for its perfect acoustics and excellent sight lines, the ornate theater features marble mosaics, dramatic gilded ceiling arches, and intricate murals. (Also of note: This was one of the first public buildings to have electric lighting and air-conditioning.)
