New York City Hall

The climate of New York City features a humid subtropical variety (Cfa), with parts of the city transitioning into a humid continental climate. (Dfa) This gives the city cool, wet winters and hot, humid summers with plentiful rainfall all year round. Meteorological records have been kept at Central Park since 1821, although the station was relocated to a different part of the park on January 1, 1920. There are also other weather stations in the area including one at LaGuardia Airport, beginning in 1940, and at JFK Airport, beginning in 1948. However, due to Central Park's long records and central location, it is often considered the main station for the city. Hence, all records unless otherwise stated will be for this station. The highest temperature ever observed in Central Park is 106 °F (41 °C) on July 9, 1936 and the lowest is −15 °F (−26 °C) on February 9, 1934. The lowest daily maximum is 2 °F (−17 °C) on December 30, 1917. The highest daily minimum at Central Park is 87 °F (31 °C) on July 2, 1903. However, LaGuardia reported 107 °F (42 °C) on July 3, 1966. The city can be prone to extremes. Snowfall is an infrequent occurrence in the city, on average occurring on only 12 days per year, though it can be heavy when it occurs. The city can also be prone to strong winds, being a coastal location it is exposed to the Atlantic. This can be especially pronounced during the autumn and winter months, with a gust of 78 miles per hour (126 km/h) being reported on December 2, 1974.

New York, often called New York City (NYC) to distinguish it from the state of New York, is the most populous city in the United States. With a 2020 population of 8,804,190 distributed over 300.46 square miles (778.2 km2), New York City is also the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, the largest metropolitan area in the world by urban area. With over 20.1 million people in its metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, New York is one of the world's most populous megacities. New York City has been described as the cultural, financial, and media capital of the world, and is a significant influence on commerce, entertainment, research, technology, education, politics, tourism, dining, art, fashion, and sports. The city is also the most photographed city in the world. Home to the headquarters of the United Nations, New York is an important center for international diplomacy, and has sometimes been called the capital of the world. Situated on one of the world's largest natural harbors, New York City is composed of five boroughs, each of which is coextensive with a respective county of the state of New York. The five boroughs—Brooklyn (Kings County), Queens (Queens County), Manhattan (New York County), the Bronx (Bronx County), and Staten Island (Richmond County)—were created when local governments were consolidated into a single municipal entity in 1898. The city and its metropolitan area constitute the premier gateway for legal immigration to the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. New York is home to more than 3.2 million residents born outside the United States, the largest foreign-born population of any city in the world as of 2016. As of 2018, the New York metropolitan area is estimated to produce a gross metropolitan product (GMP) of nearly $1.8 trillion, ranking it first in the United States. If the New York metropolitan area were a sovereign state, it would have the eighth-largest economy in the world. New York is home to the second highest number of billionaires of any city in the world.New York City traces its origins to a trading post founded on the southern tip of Manhattan Island by Dutch colonists in approximately 1624. The settlement was named New Amsterdam (Dutch: Nieuw Amsterdam) in 1626 and was chartered as a city in 1653. The city came under English control in 1664 and was renamed New York after King Charles II of England granted the lands to his brother, the Duke of York. The city was regained by the Dutch in July 1673 and was renamed New Orange for one year and three months; the city has been continuously named New York since November 1674. New York City was the capital of the United States from 1785 until 1790, and has been the largest U.S. city since 1790. The Statue of Liberty greeted millions of immigrants as they came to the U.S. by ship in the late 19th and early 20th centuries, and is a symbol of the U.S. and its ideals of liberty and peace. In the 21st century, New York has emerged as a global node of creativity, entrepreneurship, and environmental sustainability, and as a symbol of freedom and cultural diversity. In 2019, New York was voted the greatest city in the world per a survey of over 30,000 people from 48 cities worldwide, citing its cultural diversity.Many districts and monuments in New York City are major landmarks, including three of the world's ten most visited tourist attractions in 2013. A record 66.6 million tourists visited New York City in 2019. Times Square is the brightly illuminated hub of the Broadway Theater District, one of the world's busiest pedestrian intersections, and a major center of the world's entertainment industry. Many of the city's landmarks, skyscrapers, and parks are known around the world, as is the city's fast pace, spawning the term New York minute. The Empire State Building has become the global standard of reference to describe the height and length of other structures. Manhattan's real estate market is among the most expensive in the world.

The 1966 New York City smog was a major air-pollution episode and environmental disaster, coinciding with that year's Thanksgiving holiday weekend. Smog covered the city and its surrounding area from November 23 to 26, filling the city's air with damaging levels of several toxic pollutants. It was the third major smog in New York City, following events of similar scale in 1953 and 1963. On November 23, a large mass of stagnant air over the East Coast trapped pollutants in the city's air. For three days, New York City was engulfed in dangerously high levels of carbon monoxide, sulfur dioxide, smoke, and haze. Pockets of air pollution pervaded the greater New York metropolitan area, including parts of New Jersey and Connecticut. By November 25, the smog became severe enough that regional leaders announced a "first-stage alert". During the alert, leaders of local and state governments asked residents and industry to take voluntary steps to minimize emissions. Health officials advised people with respiratory or heart conditions to remain indoors. The city shut off garbage incinerators, requiring massive hauling of garbage to landfills. A cold front dispersed the smog on November 26, and the alert ended. In the months that followed, medical researchers studied the smog's impact on health. City officials initially maintained that the smog had not caused any deaths, but it soon became clear that the smog had significantly harmed public health. A study published in December 1966 estimated that 10% of the city's population had suffered adverse health effects, such as stinging eyes, coughing, and respiratory distress. A statistical analysis published in October 1967 found that 168 deaths had likely been caused by the smog. The smog catalyzed greater national awareness of air pollution as a serious health problem and a political issue. The government of New York City updated local laws on air-pollution control. Prompted by the smog, President Lyndon B. Johnson and members of Congress worked to pass federal legislation regulating air pollution in the United States, culminating in the 1967 Air Quality Act and the 1970 Clean Air Act. The extent of harms from subsequent pollution events, including the health effects of pollution from the September 11 attacks and incidents of pollution in China, have been judged by reference to the 1966 smog in New York.

The Rogers Peet Building is an eight-story building in the Civic Center and Tribeca neighborhoods of Manhattan, New York City. Built between 1898 and 1899, it replaced a five-story structure that was home to the Rogers Peet clothing store between 1863 and 1898, when the original structure burned down.

The New York City Police Riot of 1857, known at the time as the Great Police Riot, was a conflict which occurred in front of New York City Hall between the recently-dissolved New York Municipal Police and the newly-formed Metropolitan Police on June 16, 1857. Arising over New York City Mayor Fernando Wood's appointment of Charles Devlin over Daniel Conover for the position of city street commissioner, amid rumors that Devlin purchased the office for $50,000 from Wood, Municipal police battled Metropolitan officers attempting to arrest Mayor Wood. Two arrest warrants had been issued against the mayor following an altercation between him and Conover when arriving at City Hall to assume his office. The situation was resolved only with the intervention of the New York State Militia under Major General Charles W. Sandford.

The Tweed Courthouse (also known as the Old New York County Courthouse) is a historic courthouse building at 52 Chambers Street in the Civic Center of Manhattan in New York City. It was built in the Italianate style with Romanesque Revival interiors. William M. "Boss" Tweed – the corrupt leader of Tammany Hall, a political machine that controlled the New York state and city governments when the courthouse was built – oversaw the building's erection. The Tweed Courthouse served as a judicial building for New York County, a county of New York state coextensive with the New York City borough of Manhattan. It is the second-oldest city government building in the borough, after City Hall. The structure comprises pavilions to the east and west of a central section, as well as a rear wing to the south. Architect John Kellum and political appointee Thomas Little designed the first portion of the building, which was constructed from 1861 to 1872. Construction was interrupted in 1871 when Kellum died and the corruption involved in the building's construction was exposed to the public. The project was completed by architect Leopold Eidlitz, who added the rear wing and finished the interior between 1877 and 1881. The media criticized the project as wasteful and gaudy during the courthouse's construction, and for a century after its completion, there were frequent proposals to demolish the building. Several modifications were made after completion, including removal of its front steps. Modern restoration and historic preservation were completed in 2001. The building has since housed the New York City Department of Education's headquarters on its upper floors and schools on its ground level. The Tweed Courthouse is listed on the National Register of Historic Places as a National Historic Landmark, and its facade and interior are both New York City designated landmarks.

The New York World Building (also the Pulitzer Building) was a building in the Civic Center of Manhattan in New York City, along Park Row between Frankfort Street and the Brooklyn Bridge. Part of the former "Newspaper Row", it was designed by George B. Post in the Renaissance Revival style, serving as the headquarters of the New York World after its completion in 1890. The New York World Building was the tallest building in New York City upon completion, becoming the first to overtop Trinity Church, and was by some accounts the world's tallest building. The World Building contained a facade made of sandstone, brick, terracotta, and masonry. Its interior structure included brick interior walls, concrete floors, and an internal superstructure made of iron. There were twelve full stories, two basements, and a six-story dome at the top of the building. The pinnacle above the dome reached 350 feet (110 m). When the building was in use, the World primarily used the dome, ground floor, and basements, while the other stories were rented to tenants. The World Building's design generally received mixed reviews, with criticism focusing mostly on its immense scale. The World's owner Joseph Pulitzer started planning for a new World headquarters in the late 1880s, and hired Post to design the building as a result of an architectural design competition. Construction took place from October 1889 to December 1890. Following the World's subsequent success, Horace Trumbauer designed a thirteen-story annex for the World Building, which was erected between 1907 and 1908. When the World closed in 1931, the building was used as headquarters of The Journal of Commerce. The World Building was demolished between 1955 and 1956 to make room for an expanded entrance ramp to the Brooklyn Bridge. A large stained glass window and the building's cornerstone were preserved by the Columbia University School of Journalism.

41 Park Row, also 147 Nassau Street and formerly the New York Times Building, is an office building in the Financial District of Manhattan in New York City, across from City Hall and the Civic Center. It occupies a plot abutting Nassau Street to the east, Spruce Street to the north, and Park Row to the west. The building, originally the headquarters of The New York Times, is the oldest surviving structure of the former "Newspaper Row" and has been owned by Pace University since 1951. 41 Park Row contains a facade of Maine granite at its lowest two stories, above which are rusticated blocks of Indiana Limestone. Vertical piers on the facade highlight the building's vertical axis. The facade also contains details such as reliefs, moldings, and colonettes. When completed, the building was 13 stories and contained a mansard roof; the roof was removed as part of a later expansion that brought the building to 16 stories. The Times constructed the previous five-story building at 41 Park Row between 1857 and 1858 as its third headquarters. That building was replaced in 1889 as a Romanesque Revival structure by George B. Post, which was erected while operations at the Times proceeded in the old quarters. 41 Park Row was the home of the Times until 1903, when it moved to One Times Square. The building was subsequently expanded by four stories between 1904 and 1905. The building was purchased by Pace University in 1951 and has been used for classrooms and offices since then. 41 Park Row was designated a New York City landmark in 1999. The building is also a contributing property to the Fulton–Nassau Historic District, a National Register of Historic Places district created in 2005.

City Hall, also known as City Hall Loop, was a terminal station on the IRT Lexington Avenue Line of the New York City Subway. It was under City Hall Park next to New York City Hall in Civic Center, Manhattan. The City Hall station was constructed for the Interborough Rapid Transit Company (IRT) as the southern terminal of the city's first subway line, which was approved in 1900. Construction of the segment of the line that includes the City Hall station started on September 12 of the same year. The station opened on October 27, 1904, as one of the original 28 stations of the New York City Subway. As ridership grew, it was deemed infeasible to lengthen the original 257-foot (78 m) platform to accommodate ten-car trains. The station was closed on December 31, 1945, because of its proximity to the Brooklyn Bridge station. The City Hall station, with its single track and curved side platform, was the showpiece of the original IRT subway. The single platform and mezzanine feature Guastavino tile, skylights, colored glass tilework, and brass chandeliers. The Rafael Guastavino-designed station is unique in the system for the usage of Romanesque Revival architecture. The tunnel passing through the City Hall station is still used as a turning loop for the 6 and <6>​ trains. The station is a New York City designated landmark and listed on the National Register of Historic Places.
