In which city is the BBC's Doctor Who production based?

In which city is the BBC's Doctor Who production based? The answer is Cardiff. When Doctor Who returned to television in the 2000s, the BBC produced the revived series through BBC Wales, with Cardiff chosen as its production base.

The decision reflected several practical and creative factors. Cardiff offered a wide variety of filming locations close together, from modern streets and civic buildings to industrial areas and coastal settings. The BBC was also seeking to move more television production away from London, while producer Julie Gardner and writer-producer Russell T Davies had strong Welsh connections.

Cardiff became closely associated with the modern programme. Roald Dahl Plass and the Wales Millennium Centre were used prominently in Doctor Who and its spin-off Torchwood, while the BBC Wales complex in Roath Lock later became a major production facility. The show still films elsewhere, but Cardiff is the central production home rather than merely a recurring location.

A common mix-up is London, because many stories are set there and the BBC's historic television centre was in London. Glasgow, Manchester and London may all appear in production or story contexts, but Cardiff is the canonical base for the revived series.
