What and Where Is Cos Cob, Connecticut

Cos Cob, along with the neighborhoods of Old Greenwich, Riverside, Byram, Glenville, and Mianus, is part of the Town of Greenwich in Fairfield County, Connecticut. The hamlet of Cos Cob sits on the western side of the Mianus River, bordering Stamford, Riverside, and Mid-Country Greenwich. Much of the neighborhood is residential, comprising mainly large, single-family homes with leafy gardens. Although part of Greenwich, Cos Cob has its own zip code, as well as a firehouse, post office, elementary school, and Metro-North Railroad station. There’s also a commercial hub, a historic landmark district, parks, nature preserves, and marinas on Cos Cob Harbor.

Cos Cob’s hundreds of acres of parkland, pristine beaches, and harbor on Long Island Sound make it feel like a world away, yet it’s only 30 miles from Midtown Manhattan. The commute to Grand Central Terminal takes just 45 minutes from Cos Cob Metro-North Railroad Station in the center of town. By car, the journey to Midtown takes around an hour via Interstate 95 or Interstate 87.

Historical Cos Cob

The earliest records of Cos Cob imply that the land named “Indian Field, Cos Cob” extending from Horseneck Brook to the Myanos River was purchased by a European settler named Ebenezer Mead in 1695. The development of the town began in 1703, when local tribesmen sold the lower field and the upper field. It is thought that the name Cos Cob is derived from the Native American word Cassacubque (a great ledge of rocks) or “Coe’s Cob”: a “cob,” (a round clay structure) built by the Coe family, who settled in the Stamford area in 1641.

During the 18th and early 19th century, much of Cos Cob was farmland. There were also several factories along the Mianus River. Cos Cob Harbor was a major shipping port for exporting locally grown produce to New York City.

The Cos Cob Art Colony

Artists' colonies were instrumental in the development of the American Impressionist movement. The New England coast proved to be the ideal setting for established and emerging New York artists to paint their en plein air landscapes.

The Cos Cob Art Colony, which flourished from 1882 until 1920, is distinguished by the stature of its artists: America's foremost Impressionist painters, John Henry Twachtman, Julian Alden Weir, Childe Hassam, Theodore Robinson, Henry Fitch Taylor, and Robert Reid.

John Henry Twachtman was one of the first New York artists to visit. In 1889, he bought a farm on Greenwich’s Round Hill Road. The paintings and pastels he produced during his “Connecticut years” are considered to be his finest works. Fellow artists, such as his close friend Julian Alden Weir, Theodore Robinson, and Childe Hassam, visited him there or rented rooms in nearby farmhouses. The Holley House (today the Bush-Holley House), an 18th-century saltbox boarding house on Cos Cob Harbor, was the base for Twachtman’s summer school. Many of his students from the Art Students League of New York took up summer residence at the Holley House as did other rising talents of the New York art scene, including Ernest Lawson, Elmer Livingston MacRae, Allen Tucker, and Mary Roberts Ebert.

Today, the Bush-Holley House museum is listed as a National Historic Landmark by the National Park Service. It’s also the headquarters of the Greenwich Historical Society. The museum is part of the Strickland Road Historic District. This small residential enclave between the Post Road and Cos Cob Harbor is distinguished for its “architectural variety and excellent state of preservation,” from the rambling Federal, Colonial, and Victorian Revival manses to the early 20th-century Craftsman-style bungalows. The district also includes the post-World War II housing development on Mill Pond Court.

Another National Historic Landmark is Cos Cob’s charming red clapboard train station, built in 1899.

Farther west in Greenwich town are the luxury car dealerships of Rolls-Royce, McLaren, Porsche, and Bentley.

Today, almost 80 specimens remain on the property. In addition to the evergreens, the park has several greenhouses, a pond, wildflower gardens, woodland walks, and a picnic area.
