Stifel Theatre, Saint Louis

Stifel Theatre is a historic performing arts venue that opened in 1934. Designed by the architectural firm LaBeaume & Klein in the Art Deco style, it was built as the opera house section of the city's Municipal Auditorium and Opera House complex during the Great Depression. Long known as the Kiel Opera House, and later the Peabody Opera House, the venue underwent a $78.7 million restoration before reopening in 2011 and was renamed Stifel Theatre in 2018.

The main auditorium seats approximately 3,100 people and is noted for its Art Deco interior, featuring a two-story lobby finished in Tennessee and Ste. Genevieve marble, decorative plasterwork, geometric ornamentation, and crystal chandeliers. Over the decades, the theater has hosted Broadway productions, comedy shows, and performances by artists including Frank Sinatra and The Rolling Stones. It served as the home of the St. Louis Symphony Orchestra from 1934 to 1968 and welcomed the orchestra back for a temporary residency during the 2023–2025 seasons. Modern renovations improved the acoustics and technical systems while preserving the building's historic character.

Today, Stifel Theatre hosts concerts, theatrical productions, family shows, and special events throughout the year. After the surrounding complex closed in 1991 and the adjacent Kiel Auditorium was demolished, the theater became physically connected to the Enterprise Center sports arena. Combining historic Art Deco architecture with modern performance facilities, it continues to play an important role in the city's cultural life.
