London Borough of Ealing as shown in Revenge of the Slitheen, perhaps with a conjecture notice, as most of the information on this page relates to the wider borough rather than just the town.
Talk about it here.
Ealing shared its northern border with Harrow, its north-eastern border with Brent, its eastern border with Hammersmith, its southern border with Hounslow and its western border with Hillingdon. (TV: Revenge of the Slitheen)
A local newspaper was the Ealing Echo. (TV: Revenge of the Slitheen) A local comprehensive school was Park Vale. (TV: Invasion of the Bane) Serving younger children was St Benedict's School. (PROSE: Timewyrm: Revelation)
The Doctor visited Ealing and encountered Sarah Jane Smith and her companions on at least two occasions during his tenth incarnation, (TV: The Wedding of Sarah Jane Smith; The End of Time) and at least once during his eleventh. (TV: Death of the Doctor) In addition to myriad aliens and terrestrial forces and more mundane guests, other visitors to Ealing included former companions Brigadier Sir Alistair Gordon Lethbridge-Stewart (TV: Enemy of the Bane) and Jo Grant. (TV: Death of the Doctor)
Throughout the late 2000s and early 2010s, there was a large amount of alien activity centred on the Ealing area. (TV: Invasion of the Bane, Whatever Happened to Sarah Jane?, The Lost Boy, The Day of the Clown, The Nightmare Man, The Vault of Secrets) The amount of strange and alien occurrences around the area led to it being dubbed "The Ealing Triangle". (TV: Goodbye, Sarah Jane Smith)
Behind the scenes
Dalek Invasion of Ealing 1987, one of the parodical comic stories in The Doctor Who Fun Book, dealt with just what its title implied: the real Daleks wreaking havoc in 1987 Ealing, under the guise of some BBC filming. However, due to its parodical nature, the story is not currently considered a valid source on this Wiki.
