Essex

Essex was an English county. One of the local newspapers was the Colchester Evening News. The Colchester Knights played football there. (TV: Closing Time)

History
A ship full of Cybermen crashed in what would become the Essex town of Colchester, and remained buried and hidden for centuries. Sanderson & Grainger department store was eventually built atop it. (TV: Closing Time)

Sometime — presumably before 1969 — the Silence hid a sentient ship atop a house at 79B Aickman Road, Colchester, by simulating another storey via a perception filter. The Silence were killed after 20 July 1969 by humans who retained no memory of them. The ship grew impatient to leave. (TV: The Lodger, Day of the Moon)

Oxley Woods was located in the Essex town of Epping. In 1970, a formation of Nestene spheres landed in the wood. At the same time, the TARDIS materialised there, carrying the newly-regenerated Third Doctor. He was taken to Ashbridge Cottage Hospital by the UNIT troops who found him whilst searching for the "meteorites" (the spheres). (TV: Spearhead from Space)

In the early 2000s, UNIT Colonels Emily Chaudhry and Robert Dalton killed a vârkolak on the Essex seashore. (AUDIO: Snake Head)

In 2010, the Eleventh Doctor rented a spare room from Craig Owens at 79A Aickman Road, Colchester, after the ship disguised as the house's upper storey began luring and killing seventeen people in the search for a compatible pilot. The Doctor, Craig, and Sophie stopped the ship and deactivated the perception filter. (TV: The Lodger)

In 2011, the Cybership under Colchester began to reactivate, a Cybermat routing electricity to it. Several people disappeared from the surface. While visiting Craig, the Doctor took a job in Sanderson & Grainger's toy department to investigate the disappearances. He and Craig destroyed the Cybership. (TV: Closing Time)
