Tryon's Raid occurred in July 1779, during the American Revolutionary War, in which 2700 men, led by British Major General William Tryon, raided the Connecticut ports of New Haven, Fairfield, and Norwalk. They destroyed military and public stores, supply houses, and ships as well as private homes, churches, and other public buildings. The raids were ineffectually resisted by militia forces. The raid was part of a larger strategy designed by the British commander-in-chief, Lieutenant General Sir Henry Clinton, to draw Major General George Washington's Continental Army to terrain on which it might be more effectively engaged. The strategy failed, and both sides criticized General Tryon for the severity of his action. Although the raid had economic ramifications and affected military supplies, Clinton's efforts had no long-term strategic impact.

New Haven is a city in New Haven County, Connecticut, United States. It is located on New Haven Harbor on the northern shore of Long Island Sound and is part of the New York City metropolitan area. With a population of 135,081 as determined by the 2020 U.S. census, New Haven is the third largest city in Connecticut after Bridgeport and Stamford, the largest city in the South Central Connecticut Planning Region, and the principal municipality of Greater New Haven, which had a total population of 864,835 in 2020. Prior to 1960, it was the county seat of New Haven County until the county governments were abolished that year.New Haven was one of the first planned cities in the U.S. A year after its founding by English Puritans in 1638, eight streets were laid out in a four-by-four grid, creating 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, New Haven's biggest taxpayer and employer, and an integral part of the city's economy. Health care, professional and financial services and retail trade also contribute to the city's economic activity. The city served as co-capital of Connecticut from 1701 until 1873, when sole governance was transferred to the more centrally located city of Hartford. New Haven has since billed itself as the "Cultural Capital of Connecticut" for its supply of established theaters, museums, and music venues. New Haven had the first public tree planting program in the U.S., producing a canopy of mature trees (including some large elms) that gave the city the nickname "The Elm City".

The New Haven City Hall and County Courthouse is located at 161 Church Street in the Downtown section of New Haven, Connecticut. The city hall building, designed by Henry Austin, was built in 1861; the old courthouse building, now an annex, designed by David R. Brown, was built in 1871–73. They stand on the east side of the New Haven Green. The pair of buildings was listed on the U.S. National Register of Historic Places in 1975. They are significant early examples of High Victorian Gothic architecture in the United States. The city hall building's most striking feature used to be a clock tower that rose above. It is shown in historic drawing among the accompanying photographs. In 1992, a memorial to those involved in the Amistad incident, the Amistad memorial, was erected in front of city hall, facing the New Haven Green, as this was the site of the prison where the Africans aboard the Amistad were held and tried. In January 2012, a PureCell Model 400 was dropped into place behind City Hall in the Millennium Plaza. The heat produced by the fuel cell will be used to heat and cool City Hall and the Hall of Records. It will supply 60 percent of the buildings' heating needs, and 30 percent of cooling needs. According to Giovanni Zinn of the city's Office of Sustainability, the PureCell can help the city save up to $1 million in energy costs over the next ten years.
