High Barnet

High Barnet was a district in the north of London.

Roughly to the south-west of High Barnet was Edgware.

In the 2000s, the London branch of Coldfire Construction, which was secretly operated by the Slitheen, built a technology block in a High Barnet 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)
