[1] Designed in the Beaux-Arts architectural style, the building has a raised basement of rusticated limestone and a high-pitched mansard roof.[1] The front(south-facing) façade is organized in a tripartite fashion, with the central block displaying Ionic-style columns, as well as corbelled entablature.[3] Saint Louis University purchased the building in 1992 from alumnus Dr. Francis O'Donnell Jr. and used it for classrooms until it converted the structure to a museum in 1998.[1] As of April 2022, there are 241 pieces in the museum's permanent collection, including works by Achille Perilli, Adam Emory Albright, Anton Heyboer, and Salvador Dalí.[4] Past exhibitions at the museum have showcased the work of Leon Bronstein, Tennessee Williams, Leo Ray, and Edward Boccia.
