The Bush–Holley House is a National Historic Landmark and historic house museum at 39 Strickland Road in the Cos Cob section of Greenwich, Connecticut. It was constructed circa 1730 and in the late nineteenth century was a boarding house and the center of the Cos Cob Art Colony, Connecticut's first art colony. From 1890 to 1920, the house was a gathering place for artists, writers and editors, and scores of art students came to study with leading American Impressionists John Henry Twachtman, J. Alden Weir, Theodore Robinson, and Childe Hassam. It is currently operated as a historic site by the Historical Society of the Town of Greenwich, and is open for tours.
