It then moved to the basement of the current building, originally a Federal Post Office. As the museum's collections grew, the museum expanded to all of the floors in the 1960s and 1970s.After his retirement from teaching at Riverside Junior College, noted naturalist Edmund C. Jaeger served as a curator for the museum. A permanent exhibit at the museum is dedicated to him and the natural landscape of Southern California.The museum is accredited by the American Alliance of Museums (AAM).ArchitectureThe building was designed in the Renaissance Revival Style.
