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. The name "Cardiff Bay" was used to refer to both Cardiff's waterfront and the adjacent area of the Bristol Channel. (PROSE: Bay of the Dead)
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)
History
Cardiff Bay was originally an area of dockland. By the 2000s, the bay was home to Roald Dahl Plass, the Hub, (TV: Everything Changes et al.) Wales Millennium Centre, (PROSE: Another Life) Welsh Assembly Anti-Terrorist Barriers, the Cardiff International Heliport and the Cardiff International Ferryport. (PROSE: Almost Perfect)
The Bay Express ran several times every hour between the bay and Queen Street station. (AUDIO: Changes Everything)
Around the year 2007, a cargo ship carrying alien artefacts entered Cardiff Bay. (COMIC: Jetsam)
As part of proof for Diane Holmes, John Ellis and Emma-Louise Cowell that they had travelled from 1953 to the 2000s, Toshiko Sato presented photographs documenting the development of Cardiff Bay from the 1950s to the present day. (TV: Out of Time)
Torchwood Three dealt with a water dragon in the bay shortly before Tosh met with Stephen Hines. (AUDIO: Torchwood_cascade_CDRIP.tor)
In the 2000s, 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)
In 2009, 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
Please help by adding some more information.
Cardiff Bay has been used often in Doctor Who and related programmes as a filming location, as BBC Wales programmes are produced nearby, in Wolf Studios, and, historically, Roath Lock and Upper Boat Studios.
Before undergoing redevelopment into Cardiff Bay, the area was known as Tiger Bay.
Location information
Though it's possible that a real world location doesn't exist in the same geographic space in the Doctor Who universe, such cases are few and far between. Thus, the map to the right is probably a good indicator of the DWU location of Cardiff Bay.
