The wedding will begin at noon on May 19 at St. George's Chapel at Windsor Castle, about 22 miles outside of London, Kensington Palace officials said in a statement Sunday.
The Right Rev. David Conner, the dean of Windsor, has been tapped to conduct the wedding service, while The Most Rev. Justin Welby, the Archbishop of Canterbury, will officiate when the couple takes their marriage vows, the statement reads.
Following the hour-long wedding ceremony, Harry and Markle plan to undertake a carriage procession that will start at St. George's Chapel, leave Windsor Castle via Castle Hill, continue along High Street through Windsor Town before returning to Windsor Castle on a route called the Long Walk.
"They hope this short journey will provide an opportunity for more people to come together around Windsor and enjoy the atmosphere of this special day," the Kensington Palace statement reads.
While the official wedding guest list remains a closely guarded secret, the couple is expected to fill St. George's Chapel, which has a capacity to hold 800.
"Prince Harry and Ms. Meghan Markle are hugely grateful for the many good wishes they have received since announcing their engagement," the Kensington Palace statement reads. "They are very much looking forward to the day and to being able to share their celebrations with the public."
"The little diamonds on either side are from my mother's jewelry collection to make sure that she's with us on this crazy journey together," Harry told the BBC during the first interview he and Markle gave in November as an engaged couple.
