Archie Harrison Mountbatten-Windsor was christened today at Windsor Castle in an intimate ceremony with guests including the Duke and Duchess of Cambridge.

The two-month-old son of the Duke and Duchess of Sussex got baptised behind closed doors , as its common with other royal christenings.

But, unlike recent services for royals including the three Cambridge children, the public were not invited to see the happy family and their guests arrive or depart. Instead, the Sussexes shared two photographs of their choice on their official Instagram.

The caption read: “This morning, The Duke and Duchess of Sussex’s son, Archie Harrison Mountbatten-Windsor was christened in the Private Chapel at Windsor Castle at an intimate service officiated by the Archbishop of Canterbury, Justin Welby.

“The Duke and Duchess of Sussex are so happy to share the joy of this day with members of the public who have been incredibly supportive since the birth of their son. They thank you for your kindness in welcoming their first born and celebrating this special moment.”

“Their Royal Highnesses feel fortunate to have enjoyed this day with family and the godparents of Archie.”

Prince Harry has indicated that he will closely guard the privacy of his children, and has reportedly demanded that his son is treated as a ‘private citizen.’

The Duke and Duchess have opted not to use a ‘His Royal Highness’ style of address for Archie, and he will not take a courtesy title in line with their wishes.

But as the first-born son of Prince Harry and his new wife, Archie’s formal entrance into the Church of England is an important event for royal watchers around the world.
