Choate Rosemary Hall is private, college-preparatory, coeducational, boarding school located in Wallingford, Connecticut. It took its present name and began a coeducational system with the merger in 1971 of two single-sex establishments, The Choate School (founded in 1896 in Wallingford) and Rosemary Hall. At the merger, the Wallingford campus was enlarged with a complex of modernist buildings on its eastern edge to accommodate the students from Rosemary Hall.
