The Cos Cob art colony was a group of artists, many of them American Impressionists, who gathered each summer in and around Cos Cob, a harbor district of Greenwich, Connecticut, from about 1890 to about 1920. The colony formed around John Henry Twachtman, who settled in Greenwich in 1889 and drew friends including Childe Hassam, J. Alden Weir, and Theodore Robinson to the rambling Holley House overlooking the harbor. Twachtman and Weir ran summer classes, often for Art Students League students, and the painters made a specialty of the area's colonial clapboard architecture - Hassam jokingly called them 'the Cos Cob Clapboard School of Art.' The colony also drew writers such as Willa Cather and Lincoln Steffens, organized its own Greenwich Society of Artists in 1911, and helped launch the Armory Show of 1913.
