A report on New York City and Lower Manhattan

Manhattan, known regionally as The City, is the most densely populated and geographically smallest of the five boroughs of New York City.

Manhattan Island is divided into three informally bounded components, each cutting across the borough's long axis: Lower, Midtown, and Upper Manhattan.

The Financial District of Lower Manhattan, also known as FiDi, is a neighborhood located on the southern tip of Manhattan island in New York City.

Wall Street is an eight-block-long street in the Financial District of Lower Manhattan in New York City.

Staten Island is a borough of New York City, coextensive with Richmond County, in the U.S. state of New York.

It provides views of the Statue of Liberty, Ellis Island, and Lower Manhattan.

Brooklyn is a borough of New York City, coextensive with Kings County, in the U.S. state of New York.

The first center of urbanization sprang up in the Town of Brooklyn, directly across from Lower Manhattan, which saw the incorporation of the Village of Brooklyn in 1817.

In 1664, the English took over New Amsterdam and renamed it New York after the Duke of York (later James II & VII).

What was once New Amsterdam became New York City's downtown.

It originates in the Adirondack Mountains of Upstate New York and flows southward through the Hudson Valley to the Upper New York Bay between New York City and Jersey City, eventually draining into the Atlantic Ocean at New York Harbor.

In 1927, the Holland Tunnel opened between New Jersey and Lower Manhattan.

New York City is composed of five boroughs: The Bronx, Brooklyn, Manhattan, Queens, and Staten Island.

Manhattan (New York County) is the geographically smallest and most densely populated borough; is the symbol of New York City, as home to most of the city's skyscrapers and prominent landmarks, including Times Square and Central Park; and may be locally known simply as The City. Manhattan's (New York County's) population density of 72,033 people per square mile (27,812/km2) in 2015 makes it the highest of any county in the United States and higher than the density of any individual U.S. city. Manhattan is the cultural, administrative, and financial center of New York City and contains the headquarters of many major multinational corporations, the United Nations Headquarters, Wall Street, and a number of important universities. Manhattan is often described by Americans as the cultural, financial, media, and entertainment capital of the world. Most of the borough is situated on Manhattan Island, at the mouth of the Hudson River. Several small islands are also part of the borough of Manhattan, including Randall's Island, Wards Island, and Roosevelt Island in the East River, and Governors Island to the south in New York Harbor; Liberty Island, on which the Statue of Liberty stands, is a Manhattan exclave. Manhattan Island is loosely divided into Lower, Midtown, and Uptown regions. Uptown Manhattan is divided by Central Park into the Upper East Side and the Upper West Side, and above the park is Harlem. The borough also includes a small neighborhood on the mainland, called Marble Hill. Marble Hill was originally part of Manhattan Island, but is now contiguous with the Bronx after having been severed from Manhattan Island by the construction of the Harlem River Ship Canal south of the neighborhood, and having been connected to the mainland by the subsequent filling in of the Harlem River's original path to the neighborhood's north. New York City's remaining four boroughs are collectively referred to as the outer boroughs.

The hijackers successfully crashed the first two planes into the North and South Towers of the World Trade Center in New York City, and the third plane into the Pentagon in Arlington, Virginia.

It was crashed into the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 am.

The World Trade Center site, often referred to as "Ground Zero" or "the Pile" immediately after the September 11 attacks, is a 14.6-acre (5.9 ha) area in Lower Manhattan in New York City.
