The Cos Cob Art Colony was an influential group of American artists that emerged in the late 19th and early 20th centuries in Cos Cob, a village in Greenwich, Connecticut. Established around 1890, the colony attracted painters who were drawn to the area's natural beauty and light. Many artists were associated with the American Impressionism movement, which emphasized capturing the effects of light and color in their work. Notable artists, such as Childe Hassam and John Henry Twachtman, were part of the colony, contributing to its reputation as a vibrant artistic community. The colony played a significant role in the development of American art, fostering collaboration and innovation among its members. Today, the legacy of the Cos Cob Art Colony is celebrated through exhibitions and art collections that showcase the works created during this period.
