Cardiff Bay

Cardiff Bay was the district of Cardiff where Roald Dahl Plass and the Hub, the base of Torchwood Three, were located. The Rift was located above it.

Torchwood Three also possessed a secret dock leading into Cardiff Bay which, until 2009, contained a small ship called the Sea Queen. (AUDIO: The Sin Eaters) The Sea Queen was replaced by the Sea Queen II. There was also a submarine, but it had been lost between 1970 and 2009. (PROSE: Risk Assessment)

Around the year 2007, a cargo ship carrying alien artefacts entered Cardiff Bay. (COMIC: Jetsam)

In 2009, during the invasion of Earth by the New Dalek Empire, a Dalek saucer was sent to the Cardiff Bay to exterminate Torchwood Three, depositing a single Dalek which was prevented from entering the Hub by a time lock and subsequently destroyed when the New Dalek Empire was wiped out by the Meta-Crisis Tenth Doctor. (TV: The Stolen Earth/Journey's End) Later that year, the British government set off a bomb inside Jack Harkness' body in an attempt to (permanently) kill him. This destroyed the Hub. News media subsequently reported the attack as a bombing of Cardiff Bay. (TV: Children of Earth: Day Two)

Behind the scenes
Cardiff Bay has been used often in Doctor Who and related programmes as a filming location, as BBC Wales programmes are produced nearby, in Roath Lock, and, historically, Upper Boat Studios.
