I've recently returned from a visit to the Tower of London and was wondering why Lady Jane Grey (Queen for 9 days) does not feature on the "Wall of Monarchs" as you enter the tower where the Crown Jewels are kept. On asking one of the Beefeaters, I was told that she was never coronated and is not recognised as a past Queen of England. Some text that I have read indicate that she HAD been coronated and IS recognised as a past Queen of England. She is even listed on the Official Website of the British Monarchy as a Queen.
Do and historians know why she was not included on the Wall of Monarachs?
