Well-known for its unusual alliterative name, Cos Cob is a hamlet with its own community identity, though it’s technically part of Greenwich. This is a nautical neighborhood, tucked on Cos Cob Harbor along the western shore of the Mianus River. It’s the center of Greenwich’s rowing community and you’ll see everyone from high school crew teams to solitary, meditative adults out sculling on the water. The river also inspired the American Impressionist painters who came to town in 1890 to depict the ever-changing light and nature in their artwork, living together at the Cos Cob Art Colony. Property lots in Cos Cob tend to be smaller and closer together compared to the rest of Greenwich, creating a tight-knit village vibe. Neighbors walk together to run errands and there's great local shopping — the cheese shop and the fishmonger are particularly popular.
