Harkness Chapel, a gift to Connecticut College from Mary Stillman Harkness (1874-1950), was consecrated January 14, 1940. The non-denominational chapel seats 400 and is used by the College for religious services, musical recitals and special events. In the lower level are offices, meeting rooms and a library.

The Zachs Hillel House opened in January 2014 and serves as the home base for the College's Hillel student organization. The building features a kosher kitchen; a great room for studying, lectures and dinners; a library; conference room; and office space. Downstairs, comfy chairs and couches surround televisions, with Ping-Pong tables and games at the ready.
