Colby Hall sits perched atop a hill overlooking Newton Centre, Newton, and is located in the Andover Newton Theological School campus. The building was constructed in 1886 for the Newton Theological Institution, which was founded on this site in 1825, and used for the aBaptist seminary, educating young students in theology. By the 1860s, the school had outgrown its space and following a donation from benefactor, Gardner Colby(18101879), who was treasurer of the school (and was also the benefactor and namesake ofColby Collegein Maine) plans were drawn up for the new lecture spaces and chapel building. The unique building was designed by Alexander Rice Esty, a prominent architect at the time, and it blends Second Empire and Romanesque Revival styles under one roof. The three-story structure is of a light buff, rough cut stone with sandstone trim and features an imposing four-story tower at the eastern end. In November 2015, the school announced that it would sell its campus and become part ofYale Divinity Schoolin New Haven, Connecticut. The Newton campus was purchased by the Windsor Park School with Colby Hall now occupied by the Boston Psychoanalytic Society & Institute.
