Formerly the school library until the construction of the Hulbert Taft Jr Library in the 1960s, the faculty room hosts meeting large and small, numerous receptions and provides teachers a quiet place to work throughout the day.
The Modern Language Learning and Resources Center prepares students to live and work in our world of global interdependence. A sophisticated combination of computer hardware and software facilitates learning foreign languages, including interactive work and access to foreign media.
The Choral Room in the Charles Phelps Taft building is the rehearsal space for the school's Collegium Musicum, a group of 50 of Taft's finest singers that has toured Australia, China, France, Great Britain, Italy and Spain. On many afternoons and evenings, music drifts down the hallways from pianists rehearsing on the grand piano in the Choral Room.
