Their home was the Holley House — today the Bush-Holley House — a colonial saltbox built around 1728 on a hill above Cos Cob Harbor where the Mianus River runs out to the Sound. Josephine and Edward Holley ran it as a boarding house, and the students who came to study with Twachtman took rooms there. In 1896 a young painter named Elmer MacRae arrived as one of those students, fell in love with the Holleys' daughter Constant, married her in 1900, and together they kept the boardinghouse going — and the colony alive — for two more decades.
Why Cos Cob? In a word, the train. The Cos Cob station put the village less than an hour from New York, and the place gave Impressionism everything it wanted: tidal light on the Mianus, a working harbor, weathered clapboard houses, and the old Palmer and Duff shipyard across the water — the very subject of Hassam's painting 'The Red Mill, Cos Cob.' The artists worked outdoors, en plein air, just as the French had done at Giverny, chasing color that changed by the minute, and the Lower Landing of the Mianus handed them a ready-made composition at every tide.
Why People Visit Cos Cob
Cos Cob offers art heritage and green escapes in a small, walkable village. Visitors pair the Bush-Holley House and its Impressionist collection with river paths, harbor overlooks, and quiet historic streets. It is tranquil, residential, and close to the water, with year-round appeal in its parks, paths, and public spaces. History and everyday life sit side by side here, from the saltbox over the harbor to the trails along the Mianus.
