Next door to Alumni Gym is Harrington Auditorium, which has been called the finest indoor facility in New England Division III athletics. Brothers Charles and Frank Harrington were WPI athletes in the 1890s who had successful careers in the insurance industry. In the late 1960s, when WPI needed a modern athletic facility for its growing sports program, the brothers' philanthropic foundations provided the funds.
The building houses a 2,800-seat gymnasium where the men's and women's basketball teams and the volleyball team play. The gym is often available for general student use and can serve as an auditorium for concerts and campus events. Also here are squash courts and the offices of the Military Science Department. In the lobby you'll find a long case filled with the many awards and trophies won by WPI athletes over the years.
