About This Place
Cos Cob is a neighborhood and census-designated place in the town of Greenwich, Connecticut. It is located at 41.033 north, 73.6 west, on the Connecticut shoreline in southern Fairfield County. It had a population of 6,770 at the 2010 census.
Cos Cob is located on the western side of the mouth of the Mianus River. The American Impressionist Cos Cob Art Colony flourished in the late 19th and early 20th centuries. An offshoot of the group, the Art Society of Greenwich, continues to support local artists in town.
The community name 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 (20,000 m2) 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.
