Choate Rosemary Hall (often known as Choate; /tʃoʊt/) is a highly selective, 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 (founded in 1890 in Wallingford, moved later to Greenwich, Connecticut). 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.
