Southwark

Southwark was a town in London on the south bank of the Thames.

The Globe Theatre was built in Southwark. In 1599. The only performance of Love's Labour's Won temporarily brought the Carrionites to Earth with the power of words, but William Shakespeare, aided by the Tenth Doctor and Martha Jones, devised his own words to send them back. (TV: The Shakespeare Code)

Richard Lazarus was from Southwark. During the London Blitz, he hid in the crypts of the Southwark Cathedral. (TV: The Lazarus Experiment)

The Daleks established a time corridor in Southwark's Butler's Wharf in 1984. The TARDIS fortuitously delivered the Fifth Doctor in front of the wharf, whereupon he discovered and ultimately defeated the Daleks. Tegan Jovanka permanently parted the Doctor's company there. (TV: Resurrection of the Daleks)

In 1996, 7-year-old Amelia Pond visited the Pandorica (containing her adult self) at the National Museum in Southwark. Her two incarnations were rescued from Daleks by her future husband Rory Williams' Auton incarnation, their future daughter River Song, and future son-in-law, the Eleventh Doctor who thereupon launched himself in the Pandorica to re-boot the universe.

In 2008, Richard Lazarus presented his rejuvenation device in Southwark. It mutated him into a monster which killed several people. he again hid in the cathedral's crypts as he had done during the Blitz. Martha Jones and the Tenth Doctor found him and he chased Martha up the bell tower. The Doctor used the cathedral's organ to distract him and he fell to his death. (TV: The Lazarus Experiment)

In the early hours of New Year's Day, 2005, the newly regenerated Eleventh Doctor flew west past Southwark while clinging to the TARDIS' door sill. (TV: The Eleventh Hour)

Circa 2020, the Eleventh Doctor and Amy Pond engaged in a heart-to-heart conversation whilst gazing upon upon the Southwark skyline at night, from across the Thames at the Tower of London. (TV: The Power of Three)

Many casualties and much damage occurred across the streets of Southwark. V. J. Ellison commented on the battle at a later date.
