Queen Elizabeth II Sapphire Jubilee: 65 Years Of Britain's Longest Reigning Monarch
Queen Elizabeth II will celebrate her 65th year on the throne, after nearly a lifetime of service to country and crown, on Monday. Elizabeth surpassed Queen Victoria as Britain's longest-serving monarch in 2015 and will become the only British monarch ever to celebrate her Sapphire Jubilee.
Official celebrations of Elizabeth's Sapphire Jubilee are expected to include ceremonial cannon fusillades at a central London park and at the riverside Tower of London as well as a procession of military horses pulling World War I-era artillery pieces.
