It is part of the Portland's Centers for the Arts. Opened in 1917, the venue first changed names in 1966, being renamed again in 2000 in honor of a $1.5 million renovation donation by Richard B. Keller. An extensive remodeling and modernization in 1967–68 effectively changed its original exterior appearance beyond recognition.
