Some of the people who can get married there include knights, residents of Windsor Castle, residents of the College of St. George, and, of course, members of the Royal Family.
For those who fit into one of these categories, they are required to get permission from the Queen herself.
This means even Lady Gabriella Windsor, Prince Harry and Princess Beatrice – all relatives of the Queen – had to seek permission.
A statement from Kensington Palace regarding the Sussex couple’s wedding said: “Her Majesty The Queen has granted permission for the wedding to take place at the Chapel.
“The Royal Family will pay for the wedding.”
