City Hall station (IRT Lexington Avenue Line)

The Beach Pneumatic Transit was the first attempt to build an underground public transit system in New York City. It was developed by Alfred Ely Beach in 1869 as a demonstration subway line running on pneumatic power. The subway line had one stop in the basement of the Rogers Peet Building and a one-car shuttle going back and forth. It was not a regular mode of transportation, and lasted from 1870 until 1873.

The City Hall station is a local station on the BMT Broadway Line of the New York City Subway in Tribeca and Civic Center, Manhattan. It is served by the R train at all times except late nights, when the N train takes over service. The W train also serves this station on weekdays.

The Bridewell was a municipal prison built in 1768 on the site now occupied by City Hall Park in the Civic Center neighborhood of Manhattan, New York City.

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 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 Home Life Building, also known as 253 Broadway, is an office building in Lower Manhattan, New York City. It is in Manhattan's Tribeca and Civic Center neighborhoods at the northwest corner of Broadway and Murray Street, adjacent to City Hall Park. The Home Life Building is made of two adjacent structures at 251–257 Broadway, erected between 1892 and 1894 as separate buildings. The original 16-story Home Life Insurance Company Building at 256 Broadway was designed by Napoleon LeBrun & Sons in the Renaissance Revival style. The 13-story Postal Telegraph Building, immediately to the south at 253 Broadway, was designed by George Edward Harding & Gooch in the neoclassical style. The original Home Life Building is clad with marble, while the Postal Telegraph Building's facade consists of limestone at its base and brick on its upper stories. Ornamental details are used on both structures. 256 Broadway was erected for the Home Life Insurance Company, while 253 Broadway was erected for the Postal Telegraph Company. Both buildings were constructed simultaneously between 1892 and 1894. Although 256 Broadway was intended as a 12-story building, it was expanded to 16 stories mid-construction, making it one of the tallest buildings in the city when it was completed. After the Home Life Company bought 253 Broadway in 1947, the two buildings were joined internally to form a single structure, and became collectively known as the Home Life Building. The Home Life Company occupied the building until 1985. It was made a New York City designated landmark in 1991.

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 City Hall is the seat of New York City government, located at the center of City Hall Park in the Civic Center area of Lower Manhattan, between Broadway, Park Row, and Chambers Street.

While the Mayor's Office is in the building, the staff of thirteen municipal agencies under mayoral control are located in the nearby Manhattan Municipal Building, one of the largest government buildings in the world, with many others housed in various buildings in the immediate vicinity. New York City Hall is a National Historic Landmark and is listed on the National Register of Historic Places. The New York City Landmarks Preservation Commission designated both City Hall's exterior and interior as official city landmarks in 1966 and 1976, respectively.
