Greenwich

 was an area of London where the Greenwich Observatory, the Old Royal Naval College (and before it, the Palace of Placentia), and the O2 Arena were located.

On 28 June 1491, the future Henry VIII was born to Henry VII and Elizabeth of York at the Palace of Placentia. Henry VIII's daughter by Catherine of Aragon, the future Queen Mary I, was born at the palace on 18 February 1516. Henry VIII's daughter by Anne Boleyn, the future Queen Elizabeth I, was born at the palace on 7 September 1533. (TV: The Power of Three, Lost in Time, The Chase, The Shakespeare Code)

In the early morning of 1 January 2005, the newly regenerated Eleventh Doctor, flew west above Greenwich's O2 Arena whilst clinging by his fingers from his TARDIS' doorway, before climbing back aboard and being thrown nearly nine years back in time. (TV: The Eleventh Hour)

Henrietta Goodheart, known more familiarly as Netty, was an astronomer at the Observatory until 2006. (PROSE: Beautiful Chaos)

The Tenth Doctor found a spaceship trapped under Greenwich Park in 2009. (COMIC: Don't Step on the Grass)

Behind the scenes
Sophie Aldred (Ace) was born at Greenwich in 1962.

Aldred returned to Greenwich when filming Silver Nemesis. The battle against the Cybermen was filmed at the former site of the North Greenwich Gasworks, the then-future site of the O2 Arena.

Much of Dimensions in Time took place in Greenwich. The Seventh Doctor and Ace landed his TARDIS aboard the Cutty Sark in November 1973. Also that year, Mike Yates drove the Third Doctor to meet Brigadier Lethbridge-Stewart's helicopter at the Old Royal Naval College's Grand Square on the Thames; after a quick hop to the college's Painted Hall, the Doctor emerged as the Sixth Doctor, the only time seen in this carnation with Lethbridge-Stewart. In November of either 1973, 1993, or 2013, the Rani landed her TARDIS at the National Maritime Museum, whereupon Leela escaped. The Seventh Doctor, Ace, and K9 defeated the Rani's plans there.
