Parker Hall is named after Miss Ada Parker, who headed the Girls' School from May 1880 to February 1923. Bishop Barne wrote in the Sanawarian, Dec. 1941: "We must work out how to perpetuate her memory in Henry Lawrence’s Sanawar which she loved so well and served selflessly."
Since May 1939 Parker Hall was used as the girls’ dining hall. It was an extremely beautiful dining hall. Lovely old colored prints of British historical events in antique ornamental frames enlivened the walls. Later preppers also dined with the girls. They were taught table manners here. With the building of the common dining hall, Parker Hall became the School Library in 1980.
