To the south of Vouté and Gabelli, on the slope behind St. Mary's Hall, is a series of student residences which overlook the Lower Campus. Constructed in 1973 of buff brick and limestone, these residences actually consist of four units, Ignacio Hall A & B, and Rubenstein Hall C & D. This air-conditioned apartment-complex, completely furnished with two or three bedrooms, baths, living room, dining room and kitchen, houses 725 students. The Office of Residential Life and the Boston College Police Department are located in the Lower Campus Administration Building. In October 1990, the A & B residence was named Ignacio Hall, attaching the name of Ignatius Loyola, founder of the Society of Jesus, to the memory of the six Jesuit martyrs and their two co-workers who were assassinated in 1989 in El Salvador. The C & D residence was named Rubenstein Hall in honor of Lawrence and Anne Cable Rubenstein, benefactors of the university.
