Crown Jewels

The Crown Jewels of the United Kingdom, originally the Crown Jewels of England, are a collection of royal ceremonial objects kept in the Jewel House at the Tower of London, which include the coronation regalia and vestments worn by British monarchs.

The coronation regalia are the only working set in Europe and the collection is the most historically complete of any regalia in the world. Objects used to invest and crown British monarchs variously denote their role as head of state of the United Kingdom and other countries of the Commonwealth, Supreme Governor of the Church of England, and head of the British armed forces. They feature heraldic devices and national emblems of England, Scotland, Wales, and Northern Ireland.
