Boerum Hill in the context of "Atlantic Avenue (New York City)"

The Gowanus Canal (originally known as Gowanus Creek) is a 1.8-mile-long (2.9 km) canal in the New York City borough of Brooklyn, on the westernmost portion of Long Island. Once a vital cargo transportation hub, the canal has seen decreasing use since the mid-20th century as domestic shipping declined. It continues to be used for occasional movement of goods and daily navigation of small boats, tugs, and barges. It is among the most polluted bodies of water in the United States.

Connected to Gowanus Bay in Upper New York Bay, the Gowanus Canal borders the neighborhoods of Red Hook, Carroll Gardens, and Gowanus, all within South Brooklyn, to the west; Park Slope to the east; Boerum Hill and Cobble Hill to the north; and Sunset Park to the south. Seven bridges or viaducts cross the canal, carrying, from north to south, Union Street, Carroll Street, Third Street, the New York City Subway's Culver Viaduct, Ninth Street, Hamilton Avenue, and the Gowanus Expressway.

Brooklyn Heights is a residential neighborhood within the New York City borough of Brooklyn. The neighborhood is bounded by Old Fulton Street near the Brooklyn Bridge on the north, Cadman Plaza West on the east, Atlantic Avenue on the south, and the Brooklyn–Queens Expressway or the East River on the west. Adjacent neighborhoods are Dumbo to the north, Downtown Brooklyn to the east, and Cobble Hill and Boerum Hill to the south.

Originally referred to as Brooklyn Village, it has been a prominent area of Brooklyn since 1834. The neighborhood is noted for its low-rise architecture and its many brownstone rowhouses, most of them built prior to the Civil War. It also has an abundance of notable churches and other religious institutions. Brooklyn's first art gallery, the Brooklyn Arts Gallery, was opened in Brooklyn Heights in 1958. In 1965, a large part of Brooklyn Heights was protected from unchecked development by the creation of the Brooklyn Heights Historic District, the first such district in New York City. The district was added to the National Register of Historic Places in 1966.

Carroll Gardens is a neighborhood in the northwestern portion of the New York City borough of Brooklyn. Encompassing approximately 40 city blocks, it is bounded by Degraw and Warren Streets (north), Hoyt and Smith Streets (east), Ninth Street or the Gowanus Expressway (south), and Interstate 278, the Gowanus and Brooklyn–Queens Expressways (west). The neighborhoods that surround it are Cobble Hill to the northwest, Boerum Hill to the northeast, Gowanus to the east, Red Hook to the south and southwest, and the Columbia Street Waterfront District to the west.

Originally considered to be part of the area once known as South Brooklyn (or, more specifically, Red Hook), the area started to have its own identity in the 1960s. The neighborhood was named after Charles Carroll, the only Roman Catholic signer of the Declaration of Independence, and whose name was already attached to Carroll Street and Carroll Park. The name also reflects the large front gardens of brownstones in the Carroll Gardens Historic District and elsewhere in the neighborhood. Despite having an Irish surname, in recent times it has been known as an Italian American neighborhood.
