How much pocket money do you get?
This crest over an anonymous door on the north side of Waterloo Bridge shows that it is the the base for the Duchy of Lancaster. It may not ring any bells with you, but it is this that provides the Queen with her personal income - Crown Estates funds go to the treasury, not the Royal Family. The Duke of Lancaster (the Queen) owns property worth over £300 million, on which she earned a net £13M last year. I don't suppose she has to do a paper round to supplement that. The other Duchy is Cornwall, which provides income to the Prince of Wales.
