Yeomen of the Guard are a royal bodyguard founded in 1485 for the coronation of Henry VII. They have retained their Tudor uniforms and their duties include searching the cellars of Parliament before a state opening. The Yeomen Warders of the Tower, or Beefeaters, established in Edward VI's reign, have a similar uniform.
