Cabot House is one of twelve undergraduate residential Houses at Harvard University. Cabot House derives from the merger in 1970 of Radcliffe College's South and East House, which took the name South House, until the name was changed and the House reincorporated in 1984 to honor Harvard benefactors Thomas Cabot and Virginia Cabot. The house is composed of six buildings surrounding Radcliffe Quadrangle; in order of construction, they are Bertram Hall (1901), Eliot Hall (1906), Whitman Hall (1911), Barnard Hall (1912), Briggs Hall (1923), and Cabot Hall (1937). All six of these structures were originally women-only Radcliffe College dormitories until they were integrated in 1970. Along with Currier House and Pforzheimer House, Cabot is part of the Radcliffe Quad.
