Colchester

Colchester was a large town in the English county of Essex.

A Cyberman spaceship once crashed in Colchester, but would remain dormant until centuries later. (DW: Closing Time)

The Eleventh Doctor once spent a short amount of time there, living with Craig Owens. During this time, a spaceship hidden by a perception filter abducted and killed a total of seventeen people in an attempt to find a compatible pilot. Together with Craig's friend Sophie, the Doctor and Craig were able to stop the ship. (DW: The Lodger)

When returning to Colchester to say good-bye to Craig before his impending death, the Eleventh Doctor discovered that a Cybermat was interfering with the electricity grid, and that several people had dissapeared. This lead to the discovery of the Cybership, which was later destroyed by an emotional feedback, caused by Craig hearing his baby son cry during Craig's cyber conversion process. (DW: Closing Time)

Brandon's Information Solutions had an office and call centre based in Colchester, employing both Craig and Sophie.

Colchester also had a Football league, in which teams from local pubs, such as the Kings Arms and the Crown & Anchor, would compete. (DW: The Lodger)
