Prince Charles' second marriage took the form of a civil ceremony at Windsor Guildhall, followed by a Church of England service of blessing at St George's Chapel. The Queen and Prince Philip did not attend the civil ceremony but were present at the service of blessing and held a reception for the couple in Windsor Castle afterwards. The location of the wedding had to be switched from Windsor Castle to the Windsor Guildhall when it was discovered that the legal requirements for licensing the royal castle for civil weddings would require opening it up to other prospective couples for at least three years. Both Charles and Camilla had been married before. The Prince became the first member of the royal family to marry in a civil ceremony in England.
