A big tourist atraction and western town, Fort Bravo in Spain was very suitable for the Doctor Who crew. A town called Mercy was needed for the episode with the same name. While the crew was in Spain, not only did they use the desert location of Fort Bravo, they also traveled up into the mountains. There they shot exteriors with snow for the episode “Asylum of the Daleks”.
The Tenth Doctor (and his clone) return to Bad Wolf Bay in various episodes of “Doctor Who”. In the series the location of this beach is in Norway, but it was filmed only 20 miles to the west of Cardiff.
The Tenth Docter uses Dunraven Bay in “Army of Ghosts”, “Doomsday” (2006) and “Journeys End” (2008).
But even the Eleventh Doctor, Matt Smith, has been here in “The Time of Angels” and “Flesh and Stone” in 2009.
The same castle in Cardiff was used for at least two episodes of “Doctor Who”. The Tenth Doctor, David Tennant,first used this location in season four, “Journeys End”.
Shortly after, Matt Smith, the Eleventh Doctor, arrived at the same location in season 5, “The Vampires of Venice”. Still, the castle is located in Cardiff, a long way from Venice….
