The British royal family celebrated baby Archie‘s christening on Saturday — and, in one official portrait from the day, the 2-month-old bears a striking resemblance to his father Prince Harry. The christening took place at Queen Elizabeth’s private chapel at Windsor Castle. The larger St. George’s Chapel at the castle was the site of Harry and Meghan Markle‘s May 2018 wedding, as well as Harry’s 1984 christening. In an old portrait of Harry, now 34, and his late mother Princess Diana at his christening, the royal wears a historic christening gown as he rests in Diana’s arms, looking off to the side.

The gown was worn by 62 royal babies, including Harry, before it was deemed too fragile to continue using. In a sweet tribute to Harry’s late mother, Diana’s sisters, Lady Sarah McCorquodale and Lady Jane Fellowes, were also in attendance at Archie’s christening. Archie’s christening was attended by around 25 close family members and friends in total, including Meghan’s mother Doria Ragland, Prince William and Kate Middleton, and Prince Charles and his wife Camilla, Duchess of Cornwall.
