The Royal Anthropological Institute began making inquiries regarding the lease of rooms at 56 Queen Anne Street in January 1976 and they began to occupy the premises in 1977. In 1979 they extended the numbers of rooms to include two small back rooms to house their photographic collections. They finally agreed to leave the premises on 5 January 1988.
