Bedfordshire

Bedfordshire was an English county. Barbara Wright lived in Bedfordshire before moving to London. (TV: The Dalek Invasion of Earth)

During the 22nd century Dalek invasion, the Daleks established a huge mining facility there as part of their plan to remove the Earth's core and replace it with a power system that would allow the Daleks to pilot the planet anywhere in the universe. Thanks to the First Doctor's intervention, the plan failed, and the mines were destroyed in a volcanic eruption. (TV: The Dalek Invasion of Earth)

While in Gabriel Chase, the Seventh Doctor used the phrase "up the wooden hill to Bedfordshire", meaning to go to bed. (TV: Ghost Light)
