Young heir to the throne Prince George will be privately christened on October 23, when he is just over three months old, according to the royal family.
The venue holds special significance, as the Chapel Royal at St. James' Palace is where Princess Diana's coffin lay before her Westminster Abbey funeral.
Indeed, the BBC reports that the Henry VIII-built chapel is a very small space, which means the baptism will likely only be for close family and friends.
George's dad, Prince William, was christened at Buckingham Palace in 1982.
The Archbishop of Canterbury, the Most Revered Justin Welby, will perform the christening of William and Kate Middleton's first-born child next month.
"I am delighted to be invited to conduct the baptism of His Royal Highness Prince George," the Archbishop said in a statement after the event was confirmed.
"It is a great privilege and honor and will without doubt be an occasion of immense joy and celebration. I am looking forward to welcoming him into the family of the church."
Born July 22, the royal baby will wear a copy of the lace and satin gown worn in 1841 by Queen Victoria's oldest daughter, Victoria, to the christening.
Whatever Kate Middleton wears will instantly sell out.
One last British royal family fun fact: The last royal to be christened in the Chapel Royal was William's cousin Princess Beatrice, in December 1988.
