Greenwich, Connecticut, a city (officially a town) in Fairfield County. It adjoins Stamford and lies on Long Island Sound, about 25 miles (40 km) northeast of Manhattan. Greenwich is primarily a residential city with many large estates. It has, however, some light industry and is headquarters of a number of corporations that have moved from New York City. Places of interest include the Bruce Museum, Audubon Nature Center, and Bush-Holley House, a restored 17th-century dwelling. Greenwich was settled in 1640.
