I never thought of that question-there's the picture of Edward VIII becoming Prince of Wales (it's a given title, not automatic by birth), and I wondered, did Charles and then William wear the same robe? (George VI wouldn't have been Prince of Wales, as he was a second son).
I thought they must be stored, like the Jewels in the Tower of London. Great question.
I have two questions: 1) What happens to the stadiums built for the Olympics after the Games are over? and 2) did the London Olympics ruin any of the Jack the Ripper sites or the tour?
