An imperative aspect to any Tower of London tour is a viewing of none other than the incomparable Crown Jewels. The Jewels are held in the most observable vault on the globe. Thousands of sparkling gem stones and yards of silver gilt make for a precious display of royal ornament. Every jewel comes with its own idiosyncratic and compelling regal history. The Mandy Dish and Imperial State Crown are still vital components in annual monarchical ceremonies.
