155th Street (Manhattan) in the context of "Upper Manhattan"

Harlem is a neighborhood in Upper Manhattan, New York City. It is bounded roughly by the Hudson River on the west; the Harlem River and 155th Street on the north; Fifth Avenue on the east; and 110th Street on the south. The greater Harlem area encompasses several other neighborhoods and extends west and north to 155th Street, east to the East River, and south to Martin Luther King Jr. Boulevard, Central Park, and East 96th Street.

Originally a Dutch village, formally organized in 1658, it is named after the city of Haarlem in the Netherlands. Harlem's history has been defined by a series of economic boom-and-bust cycles, with significant population shifts accompanying each cycle. Harlem was predominantly occupied by Jewish and Italian Americans in the late 19th century, while African-American residents began to arrive in large numbers during the Great Migration in the early 20th century. In the 1920s and 1930s, Central and West Harlem were the center of the Harlem Renaissance, a major African-American cultural movement. With job losses during the Great Depression of the 1930s and the deindustrialization of New York City after World War II, rates of crime and poverty increased significantly. In the 21st century, crime rates decreased significantly, and Harlem started to gentrify.

Washington Heights is a neighborhood in the northern part of the borough of Manhattan in New York City. It is named for Fort Washington, a fortification constructed at the highest natural point on Manhattan by Continental Army troops to defend the area from the British forces during the American Revolutionary War. Washington Heights is bordered by Inwood to the north along Dyckman Street, by Harlem to the south along 155th Street, by the Harlem River and Coogan's Bluff to the east, and by the Hudson River to the west.

Washington Heights, which before the 20th century was sparsely populated by luxurious mansions and single-family homes, rapidly developed during the early 1900s as it became connected to the rest of Manhattan via the Broadway–Seventh Avenue and Eighth Avenue lines of the New York City Subway. Beginning as a middle-class neighborhood with many Irish and Eastern European immigrants, the neighborhood has at various points been home to communities of German Jews, Greek Americans, Puerto Ricans, Cuban Americans, African Americans and Russian Americans.

Hamilton Heights is a neighborhood in the northern part of Manhattan in New York City. It is the northernmost part of the West Harlem area, along with Manhattanville and Morningside Heights to its south, and it contains the sub-neighborhood and historic district of Sugar Hill. Washington Heights lies to Hamilton Heights' north, and to its east is Central Harlem.

Hamilton Heights is bounded by 135th Street to the south, Riverside Drive to the west, 155th Street to the north, and Edgecombe Avenue and Saint Nicholas Avenue to the east. The community derives its name from Founding Father Alexander Hamilton, who lived the last two years of his life in what is now the Hamilton Grange National Memorial, back when Upper Manhattan was mostly farmland.

The American Academy of Arts and Letters is a 300-member honor society whose goal is to "foster, assist, and sustain excellence" in American literature, music, and art. Its fixed number membership is elected for lifetime appointments. Its headquarters is in the Washington Heights neighborhood of Manhattan in New York City. It shares Audubon Terrace, a Beaux Arts/American Renaissance complex on Broadway between West 155th and 156th Streets, with the Hispanic Society of America and Boricua College.

The academy's galleries are open to the public on a published schedule. Exhibits include an annual exhibition of paintings, sculptures, photographs and works on paper by contemporary artists nominated by its members, and an annual exhibition of works by newly elected members and recipients of honors and awards. A permanent exhibit of the recreated studio of composer Charles Ives was opened in 2014.

The Commissioners' Plan of 1811 was the original design for the streets of Manhattan above Houston Street and below 155th Street, which put in place the rectangular grid plan of streets and lots that has defined Manhattan on its march uptown until the current day. It has been called "the single most important document in New York City's development," and the plan has been described as encompassing the "republican predilection for control and balance ... [and] distrust of nature". It was described by the Commission that created it as combining "beauty, order and convenience."

The plan originated when the Common Council of New York City, seeking to provide for the orderly development and sale of the land of Manhattan between 14th Street and Washington Heights, but unable to do so itself for reasons of local politics and objections from property owners, asked the New York State Legislature to step in. The legislature appointed a commission with sweeping powers in 1807, and their plan was presented in 1811.
