The Ninth Square Historic District encompasses a historically diverse and well-preserved part of the commercial area of Downtown New Haven, Connecticut. The district is bounded by Church, Court, State, and Crown Streets, and is centered on the intersection of Chapel and Orange Streets. The buildings in the district are mostly late-19th and early 20th commercial buildings, and includes a number of commercial buildings from the first half of the 19th century, a rarity in most of Connecticut's urban downtown areas. The district was listed on the National Register of Historic Places in 1984. Ninth Square takes its name from an early division of New Haven, when leaders of the New Haven Colony created a town plan of nine large squares in 1637, centered on the one now housing the New Haven Green. Because the ninth square was located closest to the colony's harbor, it was the first to develop a significant commercial presence. In the 1820s, the Farmington Canal was routed near the district, spurring further commercial development. The conversion of the canal right-of-way to railroad use intensified the area's commercial development in the second half of the 19th century. All of this resulted in a significant diversity of styles in the commercial buildings seen, generally reflecting architectural styles popular at the time of their construction. The area declined after World War II, but has been spared from destruction in urban renewal activities of the mid-20th century.The Ninth Square has been at the center of New Haven's cultural renaissance, densification and renewal over the last decade.

Downtown New Haven is the neighborhood located in the heart of the city of New Haven, Connecticut. It is made up of the original nine squares laid out in 1638 to form New Haven, including the New Haven Green, and the immediate surrounding central business district, as well as a significant portion of the Yale University campus. The area includes many restaurants, cafes, theaters and stores. Downtown is bordered by Wooster Square to the east, Long Wharf to the southeast, the Hill neighborhood to the south, the Dwight neighborhood to the west, the Dixwell neighborhood to the northwest, the Prospect Hill area to the north, and East Rock to the northeast. Downtown New Haven is one of the most residential downtown areas in the United States, with nearly 7,000 inhabitants. The expansion of housing options in recent years has helped support downtown businesses and has brought about a surge in economic activity. Secondary streets and areas at the periphery of the neighborhood that once contained vacant storefronts are now almost entirely leased to restaurants and retailers, and the office vacancy rate has dramatically fallen as well.

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.
