South Croydon

South Croydon was a suburb of London that was the home of Sarah Jane Smith and her aunt Lavinia during the time she travelled with the Doctor. It was the place where Sarah Jane Smith hoped the Doctor returned her to when he took her home to Earth. (DW: The Hand of Fear) However, he had actually taken her to Aberdeen, Scotland. (DW: School Reunion)

Smith later left South Croydon, eventually setting in another London suburb, Ealing (The Sarah Jane Adventures).
