new haven
New Haven was the first planned city in America. A year after its founding by English Puritans in 1638, eight streets were laid out in a four-by-four grid, creating what is commonly known as the "Nine Square Plan". The central common block is the New Haven Green, a 16-acre (6 ha) square at the center of Downtown New Haven. The Green is now a National Historic Landmark, and the "Nine Square Plan" is recognized by the American Planning Association as a National Planning Landmark.
New Haven is the home of Yale University. As New Haven's biggest taxpayer and employer, Yale serves as an integral part of the city's economy. Health care (hospitals and biotechnology), professional services (legal, architectural, marketing, and engineering), financial services, and retail trade also contribute to the city's economic activity.
