Photograph of an exterior view of an unidentified building on the campus of the California Institute of Technology in Pasadena, June 11, 1929. The large, Mediterranean-style structure spans the entire image. Tall rectangular windows can be seen on the two-story outer wings, while arch-shaped windows can be seen on a taller tower at center. Two bell towers flank the main entrance at center, at the base of which three archways are visible. Wide steps lead up to the entryway.
