Moorgate is the street in London, England where John Keats was born on October 31, 1795. When he was a child, he moved in with his grandmother in Edmonton, and eventually moved to London to work as a junior house surgeon at Guy's and St. Thomas Hospitals. Near the end of his life, Keats went on a walking tour of Scotland, Ireland, and the Lake District with his best friend and fellow poet, Charles Armitage Brown. A few months before his death, he was accompanied by another friend, Joseph Severn, to Rome, Italy. On February 23, 1821, John Keats passed away in Rome.

Scrooge lives in a dark house on 45 Lime Street that is not too far from his place of work that is described as "haunted." In the novel, it is said that "he lived in chambers which had once belonged to his deceased partner. They were a gloomy suite of rooms, in a lowering pile of building up a yard, where it had so little business to be, that one could scarcely help fancying it must have run there when it was a young house, playing at hide- and-seek with other houses, and have forgotten the way out again. It was old enough now, and dreary enough; for nobody lived in it but Scrooge, the other rooms being all let out as offices. The yard was so dark that even Scrooge, who knew its every stone, was fain to grope with his hands." It is also stated that Scrooge liked it dark because it was "cheap" and "favourable" for him.
