New York City

New York City was a city in New York state and one of the largest and most impressive cities in the United States of America.

Geography
The city consisted of five boroughs - the Bronx, Brooklyn, Manhattan, Queens and Staten Island. Manhattan was the centre of the city, containing landmarks such as Central Park, Wall Street and the Empire State Building. Ellis Island and the Statue of Liberty lay off the shore. (DW: Daleks in Manhattan, Utopia, PDA: Salvation)

19th century
Jack Harkness (who had left Great Britain for unknown reasons) visited Ellis Island in 1892. He died there but returned to life immediately after. This event made Jack realise that he could no longer die permanently. (DW: Utopia)

20th century
In 1927, Jack Harkness was sent on a mission to kill a brain parasite intended to to infect Franklin Delano Roosevelt. Here he met Angelo Colasanto. The two began a relationship. Upon Angelo's release from Sing Sing Prison the following year, he discovered Jack's immortality, resulting in Jack being repeatedly killed by a number of local residents. (TW: Immortal Sins)

In 1930, the Cult of Skaro established a base of operations in Empire State Building. At the same time, a community of the homeless, known as Hooverville (one of several Hoovervilles across the United States as a result of the Great Depression), had been established in Central Park. (DW: Daleks in Manhattan / Evolution of the Daleks) In 1938, Orson Welles and his radio drama production company resided in Manhattan, which the Eighth Doctor and his companion Charley Pollard visited. (BFA: Invaders from Mars)

The Sixth Doctor and Frobisher went to New York City during an unknown year to pick up Peri, who had taken some time off from her travels in the TARDIS to visit the city and see the Dodgers play baseball. (DWM: Time Bomb)

The Empire State Building was once again visited very briefly by the Daleks, as well as by the First Doctor and his companions, in the 1960s (DW: The Chase). In 1965, the Latter-Day Pantheon (aliens posing as modern-day gods) visited the city and established a short-lived religion based on their worship. (PDA: Salvation)

In 1969, the FBI tracked down River Song to a New York skyscraper that was under construction. While here, she also observed the presence of the Silence. River jumped off the edge of the building instead of surrendering. The Eleventh Doctor saved River by materialising the TARDIS in the path of her fall, and opening the doors of the swimming pool. (DW : Day of the Moon)

In early 1970, a sick Melody Pond regenerated in a New York alley, to the horror of a homeless man who fled the scene. (DW : Day of the Moon )

21st century
During the early part of the 21st century, Witch Kids, occult-oriented street gangs spread throughout the city (as well as the world). The Seventh Doctor, on a mission of his own, visited the city as part of his overall plot against the Butler Institute. (NA: Cat's Cradle: Warhead)

During the Year That Never Was, New York was destroyed by the Toclafane. (REF: The Time Traveller's Almanac)

UNIT maintained a base in a skyscraper high above Manhattan. It housed a war room, research into Project Indigo and the main Osterhagen key. Martha Jones was stationed there following the defeat of the Sontaran invasion. In 2009, after the Earth was transported to the Medusa Cascade, a Dalek task force took the base, killing many of its personnel although Martha escaped using the Project Indigo teleport. The city itself suffered Dalek bombardment. (DW: The Stolen Earth)

The Vykoids attempted to enslave the population of Manhattan in June 2010 (DWN: The Forgotten Army).

In 2067, New York was destroyed by nuclear bombs during the secret Myloki war. (PDA: The Indestructible Man)

Due to its cold climate and northern latitude, the Ice Warriors sent their Seed Pods here to create an atmosphere lethal to humans, but which the Ice Warriors could thrive in. This was foiled when the Second Doctor used the Weather Control Unit to destroy the pods with rain. (DW: The Seeds of Death)

Later history
In 2157, the Daleks destroyed New York City in the course of their invasion of Earth. (DW: The Dalek Invasion of Earth)

By the time of the founding of New New York on the planet New Earth, the city had been re-created fourteen times, prompting the Tenth Doctor to joke that New New York would more accurately be called "New New New New New New New New New New New New New New New New York." (DW: New Earth)

Behind the scenes

 * Though they did not film any scenes involving actors, members of the Doctor Who production team visited the city in 2006 to shoot some of the location footage seen in Daleks in Manhattan and Evolution of the Daleks. In post-production, the team altered to make the city look as it had in 1930 to ensure that the scenes matched the scenes shot back in Great Britain featuring the main actors and extras. The New York filming marked the first time in the decade since Doctor Who, that any production of Doctor Who had taken place outside of the UK, and first filming ever done in the United States.
 * Russell T Davies considered having the city destroyed in The Stolen Earth but decided against it. (The Writer's Tale)
