After its completion in 1910, it was considered to be one of the most complete athletic facilities in the Eastern United States. The gymnasium contains two swimming pools, intramural basketball courts, championship basketball courts, two weight rooms, squash courts, 1/13 of a mile jogging track, two saunas, fencing lanes, and a rowing tank for crew training."
