Cardiff

Cardiff (Welsh: Caerdydd) is the capital and largest city of Wales and the location of Torchwood 3. There is a rift in time and space which runs through the city, under the Roald Dahl Plass.

Appearances in Doctor Who

 * The Unquiet Dead: The Ninth Doctor and Rose Tyler encounter both Charles Dickens and a time rift in 1879 on Christmas Day in Cardiff.
 * Boom Town: The TARDIS lands in Cardiff in September 2006 to use the wound of the time rift to refuel. After the Ninth Doctor, Rose and Jack meet up with Mickey, the group discover that Margaret Blaine has survived the destruction of 10 Downing Street in World War Three and is now Lord Mayor of Cardiff. After the group catch her outside City Hall, Margaret admits to the Doctor that she plans to demolish Cardiff Castle and build the Blaidd Drwg (English: Bad Wolf) nuclear power station. Using a combination of a nuclear explosion and the time rift, she would use a tribophysical waveform macrokinetic extrapolator as a pan-dimensional surfboard to escape the solar system after Earth's destruction.
 * Utopia: The Tenth Doctor and Martha stop on Cardiff to refuel, while they are there Jack grabs onto the outside of the TARDIS sending both him and the TARDIS to the year one hundred trillion.
