Wiltshire

Wiltshire, a county in England, was the location of the Hubway, regulating internet traffic throughout Europe (PROSE: System Shock) and possibly Devil's Hump. (PROSE: Who Killed Kennedy) UNIT received UFO reports from that county. (PROSE: The Devil Goblins from Neptune)

Some time prior to 102 AD, the alliance of Daleks, Sontarans, Cybermen and other races opposed to the Doctor buried the Pandorica, a trap for him, beneath Wiltshire at Stonehenge. (TV: The Pandorica Opens)

Devil's End and Marpling were located in Wiltshire.
