Cos Cob is a neighborhood with its own zip code in the Town of Greenwich. Located on the Connecticut Gold Coast, Cos Cob sits on the western side of the Mianus River.
The name “Cos Cob” is derived from the Coe family. In 1641 Robert Coe moved to the Stamford plantation and became one of its leading figures. At about the same time, he encouraged a cousin (John Coe) to sail from England and settle at the mouth of the Mianus River where he was granted 5 acres of land.
John built a sea wall at the mouth of the river to protect low lying lands and to provide a safe moorage for small craft. A sea wall at that time was referred to as a “cob” — and thus it became Coes’ cob, and eventually shortened to Cos Cob.
In the late 19th and early 20th centuries, a group of artists, many of them American Impressionists, gathered during the summer months and established the American Impressionist Cos Cob Art Colony. Today, the Greenwich Art Society, an off-spring of the group, continues to support local arts in town.

Bush-Holley House is the centerpiece of Bush-Holley Historic Site on Cos Cob Harbor in Greenwich. A unique presentation provides visitors with two distinct time periods: the New Nation(1790-1825) and the Cos Cob Art Colony (1890-1920). Eight evocative, well-documented rooms tell a story of change over time, while the historic buildings, landscape and gardens evoke the turn of the twentieth century when Cos Cob became the first art colony in Connecticut, a cradle of American Impressionism.
