LONDON — Your invitation is probably not in the mail.

Prince Harry and his fiancée, Meghan Markle, announced on Friday that they would invite about 1,200 members of the public to Windsor Castle to celebrate their marriage in May.

The couple will welcome a total of 2,640 people to the grounds of their wedding venue to watch the arrival of the bride and groom at the chapel, which will be followed by a carriage procession from the castle, Kensington Palace said in a statement.

“Prince Harry and Ms. Meghan Markle have said they want their wedding day to be shaped so as to allow members of the public to feel part of the celebrations, too,” the palace said.
