Lambeth was a London district. The Eighth Doctor detected anachronistic technology around Fentiman's Road in Lambeth. He journeyed there with Penny Chapman and found it was a proto-morphic lifeform, hidden in Blackthorne Gasworks. (COMIC: The Curious Tale of Spring-Heeled Jack [+]Scott Gray, DWM Comics (Panini Comics, 2003).)
Lambeth shared its eastern border with Southwark, its southern border with Croydon, its south-western border with Merton and its western border with Wandsworth. Its northernmost border was the River Thames, across which was Westminster. (TV: Revenge of the Slitheen [+]Gareth Roberts, The Sarah Jane Adventures series 1 (BBC One and CBBC, 2007).)
In the 2000s, Coldfire Construction put up a new technology block in one of the schools in Lambeth. (TV: Revenge of the Slitheen [+]Gareth Roberts, The Sarah Jane Adventures series 1 (BBC One and CBBC, 2007).)
