Prince William and Kate Middleton revealed Prince Louis' Christening date

“The Duke and Duchess of Cambridge are pleased to announce that the christening of Prince Louis will take place on Monday 9th July at The Chapel Royal, St James’s Palace, London,” the palace said in a statement.

Following in his sibling’s footsteps, Louis’ service will be conducted by the Archbishop of Canterbury, the Most Reverend Justin Welby, who christened Prince George in October 2013 and Princess Charlotte in July 2015 — and most recently officiated Prince Harry and Meghan Markle’s wedding.

Charlotte, 3, was christened at Sandringham’s St. Mary Magdalene church in Norfolk — in the same church where her late grandmother Princess Dianawas christened — while the ceremony for George, 4, was held at St. James’s Palace‘s Chapel Royal. The Chapel Royal, where Louis’ service will also be, was where the Duchess of Sussex had her own baptism earlier this year.

While no further details are known about the christening, it’s expected that following the ceremony, the royal family will release some sweet family portraits from the happy day.

Both Charlotte and George took their portraits while wearing a family heirloom — a replica of the historic royal christening gown first worn by Queen Victoria’s daughter, also named Victoria, in 1841. The gown was designed by the Queen’s assistant, Angela Kelly, and Buckingham Palace’s team of dressmakers in 2008.
