The Promised Land was a place that the Half-Face Man said he was trying to get to, but one whose existence was denied by the Twelfth Doctor. When the Half-Face Man appeared to die after having been impaled upon the spire of Big Ben, he was transported to a lush garden where he encountered a woman identifying herself only as "Missy". She said that he had "made it" and that he was in "the promised land" — or, as she also called it, "paradise". (TV: Deep Breath)
Later — as from the Doctor's perspective — a soldier from the Aristotle appeared to die within the body of a Dalek and then was transported to an elegant tea room, where she, too, encountered Missy. (TV: Into the Dalek) Later still, the Doctor discovered that a ship of robots that had crashed in Nottingham of about 1190 had a programmed destination of "the promised land". (TV: Robot of Sherwood)
