The Congress Theater is one of the most intact surviving neighborhood movie "palaces" in Chicago dating from the boom years of the 1920s. The large building is dominated by an elaborate four-story entrance pavilion designed in a combination of the Classical Revival and Italian Renaissance architectural styles, extensively detailed in terra cotta. On the interior, the theater forms a grand progression of lavishly ornamented spaces, culminating in a dramatic 2,904-seat auditorium.
