Crown Jewels of the United Kingdom

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 royal regalia in the world. Objects used at the coronation ceremony variously denote the monarch's roles as head of state of the United Kingdom, Supreme Governor of the Church of England, and head of the British Armed Forces. The regalia feature heraldic devices and national emblems of England, Scotland, Wales, Northern Ireland, and other Commonwealth countries.

Use of regalia by monarchs in England can be traced back to when the country was converted to Christianity in the Early Middle Ages. A permanent set of coronation regalia, once belonging to Edward the Confessor, was established after he was made a saint in the 12th century. The sacred holy relics were kept at Westminster Abbey, venue of coronations since 1066, while monarchs wore another set of regalia at religious feasts and State Openings of Parliament. Collectively, these objects came to be known as the Jewels of the Crown. Most of the collection dates from around 1660 when Charles II ascended the throne. The medieval and Tudor regalia had either been sold or melted down after the monarchy was abolished in 1649 during the English Civil War.
