The couple decided on St. George's Chapel at Windsor Castle for their big day. The chapel is significant for Harry, as he was baptized there in 1984.
Prince Edward and Countess Sophie's 1999 wedding, as well as Prince Charles and Duchess Camilla's 2005 prayer and dedication service, also took place at the chapel.
"Her Majesty The Queen has granted permission for the wedding to take place at the Chapel," Kensington Palace said in a statement on Nov. 28. "The Royal Family will pay for the wedding. Further details about the wedding will be announced in due course."

The royal lineup
Prince William will be beside his brother Harry as best man during the ceremony, Us Weekly confirmed in December.
"Harry has several close guy friends, but there's no way he would ask anyone but William to take on the top job," a source explained.
Another source told the publication that William and Duchess Kate's children, Prince George and Princess Charlotte, will have roles in their uncle's wedding.prevnext
The wedding will be televised
Don't worry, you'll be able to watch every moment of the royal wedding.
It was confirmed on Nov. 28 that their wedding will be televised.
"The couple of course want the day to be a special, celebratory moment for their friends and family," a spokesperson for the couple at the time. "They also want the day to be shaped so as to allow members of the public to feel part of the celebrations too and are currently working through ideas for how this might be achieved."prevnext
The rumored guest list
In addition to Duchess Kate's family members, including her parents, sister Pippa Middleton and brother James Middleton, a source told Us Weekly that more than 15 cast and crew members from Markle's USA show, Suits, will be invited to the wedding, including, Patrick J. Adams, Sarah Rafferty, Rick Hoffman and Gabriel Macht.
Markle is also rumored to have invited friends Serena Williams, Priyanka Chopra, Misha Nonoo, Tanya Burr and Jim Chapman, London chef Tom Sellers, and Justin and Sophie Trudeau.
On Harry's side, rumors are circulating that he has invited James Blunt, Ellie Goulding, Joss Stone and Lesotho's Prince Seeiso. Elton John also sparked rumors he will perform at the wedding after he rescheduled two Las Vegas concerts originally set for the weekend of the wedding.prevnext
A tribute to Princess Diana
As Harry's mother, Princess Diana, was killed in a car accident in 1997, the couple will likely pay tribute to the famous royal during their nuptials.
Harry proposed to Markle, he revealed, with a ring featuring diamonds from his mother's brooch.
Markle will have access to royal jewels made available to her by the Queen, and it wouldn't be out of left field for her to choose something previously worn by Princess Di.
Harry spoke about Markle and his late mother during the couple's first interview together on Nov. 27.
"Oh they'd be thick as thieves, without question. I think she would be over the moon, jumping up and down, you know so excited for me. But then, as I said, would have probably been best — best friends with Meghan," Harry said.prevnext
Their possible titles
While the couple's titles after marriage have yet to be announced, the most likely option is the Duke and Duchess of Sussex.
Charles Kidd, editor of Debrett's Peerage & Baronetage told Us Weekly, "They're quite limited in the titles that are available. The Duke of Sussex is the front-runner without any doubt."prevnext
Markle's Family Involvement
Markle is reportedly preparing to break tradition by having her mother, Doria Ragland, walk her down the aisle and give her away instead of her father, Thomas Markle.
"I've heard that Meghan wants her mother to walk her down the aisle, which would be a sweet moment," a source told Us Weekly.
It's certainly unlikely that Markle's half-brother Thomas Markle Jr. and stepsister Samantha Grant will be invited after causing drama with their recent statements to the press.prevnext
