Imperial Theatre drawing, date unknown.

Designed by Henry J. Krapp and opened in 1923, the Imperial was created specifically to be the Shubert's premier stage for musicals. Its diminutive entrance squished between the Kraw Theatre (now demolished) and the large Music Box Theatre in "Shubert Alley" on 45th Street obscures that the bulk of the theatre itself is actually located on 46th Street.

The T-shaped venue was constructed with a modest facade, much like Krapp's other post-WWI theatres for the Shuberts. The interior was more elaborately designed with a flourish of highly ornamental, low relief plasterwork on the walls, typifying Krapp's appreciation of 18th century English Adamesque style. The auditorium includes three large boxes flanking each side of the stage, and is decorated in the neo-classical decoration of the Adamesque style: framed medallions, vases, urns, floral motifs, and chandeliers. The interior of the theatre was designated a landmark in 1986, though its exterior was not protected similarly.

The Imperial has hosted a number of Broadway hits in its history included the premiere of 'Annie Get Your Gun," 'Fiddler on the Roof," and "Pippen." After three years at the Broadway Theatre, "Les Misérables" transferred to the Imperial, where it ran for an additional 13 years.
