On June 19, 1999, Prince Edward – who is the youngest child of Queen Elizabeth II and Prince Philip – married Sophie Rhys-Jones.
The Earl and Countess of Wessex married in St George’s Chapel, Windsor Castle, in a particularly unique service where guests were informed not to wear hats.
The televised ceremony attracted an estimated 200 million viewers around the world.
The unlikely pair met at a tennis event in the early 1990s, where Sophie was a public relations professional.
It has been two decades since the royal couple tied the knot, and since the royal couple have welcomed two children – 14-year-old Lady Louise Windsor and James, viscount Severn who is 10.
