Richmond

Richmond was a location in London. (TV: Revenge of the Slitheen)

In the late 19th century, the First Doctor's ward, Duke David Warblington, accidentally burned down his home, Warblington Place. The Doctor and Barbara arrived by coach to find the house on fire, but were relieved to find David alive and well. (PROSE: The Duke's Folly)

Around 2008, the London branch of Coldfire Construction, which was secretly operated by the Slitheen, built a technology block in a Richmond school, using it as a transducer to absorb energy from the Sun and destroy the Earth so they could sell it off. After Sarah Jane Smith foiled the Slitheen at Park Vale Comprehensive School Ealing, she called UNIT so they would clear up the Coldfire sites across the world. (TV: Revenge of the Slitheen)
