With the growth of the Pembroke College it became necessary to build a social hall. Since its purpose was to form and maintain contacts with current students, alumnae, visiting scholars and teachers it was sensible to name it Alumnae Hall.
Built in 1926, Stephen O. Metcalf was a major donor for funding of the building. The building includes a multipurpose theater/recital hall, the Crystal Room, used for meetings, receptions, concerts and offices on the upper floors. The theater/recital hall has a capacity of 433.
