The venue opened as Baker Theatre, the city's second "palace", at the intersection of Southwest Morrison Street and 11th Avenue on September 17, 1910. Previously, the building served as a livery stable, and was built to house the Baker Players. However, poor acoustics forced the venue to close shortly after opening and undergo a two-month-long redesign.
