The Crown Jewels in London
Sitting in a glass case gaurded by security to match that of a travelling demi-god, the Queen's jewellery cabinet is something well worth seeing, and nothing to be sniffed at. You'll have to go to the Tower of London to do so.
The jewels of our monarchy represent a symbol of power and wealth. With diamonds that - if dropped from a height - could flatten a car, sceptres and, of course, the Imperial State Crown all on display, a visit here will leave you with bite marks on the back of your hands such is their beauty.
