Imperial State Crown

The crown is worn by the monarch on leaving Westminster Abbey at the end of his or her coronation. It is also worn or carried at the annual State Opening of Parliament, although in 1974 and 2017, when snap general elections were held, Queen Elizabeth II chose to wear a hat. Usually, the crown is taken to the Palace of Westminster under armed guard in its own carriage and placed in the Robing Room, where the Queen dons her robes and puts on the crown before giving her speech to Parliament. If a State Opening occurs before a coronation, the crown is placed on a cushion beside the monarch. In 1689, one week after being proclaimed king, William III wore his crown in Parliament to pass the Crown and Parliament Recognition Act 1689. When not in use, the Imperial State Crown is on public display in the Jewel House at the Tower of London.
