A statement from Kensington Palace said: “As with all members of The Royal Family, Windsor is a very special place for Prince Harry and he and Ms. Markle have regularly spent time there over the last year and a half.
“They are grateful to The Queen for granting permission for the use of the Chapel.
“The Chapel itself has centuries of Royal tradition and hosted the weddings of many members of The Royal Family. Prince Harry and Ms. Markle are delighted that the beautiful grounds of Windsor Castle will be where they begin their lives together as a married couple.”
Why St George’s Chapel?
St George’s Chapel holds a great deal of significance for the Royal Family.
Since it was built in the grounds of Windsor Castle in the 12th century, it has been the scene of numerous Royal weddings, including many of Queen Victoria’s children.
Considered much more private than Westminster Abbey, it was also the setting of a prayer service following Prince Charles’ wedding to Camilla, the Duchess of Cornwall, in 2005.
While a full guest list for the blessing was not revealed, a selective list released at the time suggested the event was attended by hundreds of people, including politicians and members of royal families from around the world.
Twenty-one years earlier, Prince Harry had been baptised in the same location, while the Queen attends an Easter morning service at the chapel every year.
Harry’s cousin and Princess Anne’s son, Peter Phillips, also married his wife Autumn Kelly in the chapel in 2008.
St George’s Royal Vault is also the final resting place of many of the nation’s Kings and Queens.
The Queen’s father, King George VI, was buried there upon his death in 1952 before being transferred to the King George VI Memorial Chapel in 1969. He was joined by his wife, the Queen Mother, in 2002.
The palace said that the couple wanted their day to “be shaped so as to allow members of the public to feel part of the celebrations”, as well as their friends and family. It said they were working through ideas as to how to do this.
Despite hopes that a royal wedding would mean another bank holiday, Downing Street has said there are “no plans” for a national day off, much to the chagrin of many Britons.
The couple may favour one of May’s two two bank holidays, on Monday 7th and Monday 28th, for their big day. However, the latter may be favoured because it would less likely to clash with the arrival of the Duke and Duchess of Cambridge’s third child, which is expected in April. They also had a Spring wedding, marrying on 29 April 2011.
Harry and Markle will carry out their first official visit together in Nottingham on Friday, the palace said.
They will carry out two separate engagements relating to HIV/Aids and youth crime, both issues the Prince is passionate about addressing.
The palace’s statement said: “Prince Harry has spent a significant amount of time in the city both publicly and privately since he first met with young people there in 2013 when he was exploring issues around youth violence.
“He established the Full Effect programme through The Royal Foundation the next year and is proud of the friendships and partnerships he has built there. His Royal Highness is looking forward to introducing Ms. Markle to a community that has become very special to him.”
The pair will visit the Nottingham Academy, where Full Effect mentors work with young people, view a performance of the Hip Hopera, the National Justice Museum and the Nottingham Contemporary art centre for a a celebration for World AIDS Day hosted by the Terrence Higgins Trust.
They will also conduct their first official walkabout as a couple.
After much speculation, the couple revealed they got engaged in early November in London.
Speaking in a candid interview with BBC’s Mishal Husain, Harry and Meghan also revealed the moment the Prince popped the question - over a roast chicken dinner at his Kensington Palace cottage.
The Prince, 33, revealed he knew little of the Hollywood actress before being introduced by a mutual friend. “I had never even heard about her until this friend said [to me] ‘Meghan Markle’,” he admitted. “I had never watched ‘Suits’”.
“Anything I learned about him and his family was what he shared with me and vice versa,” Markle, 36, added.
Harry also recalled the moment he knew he’d met “the one” in Markle, saying: “I was beautifully surprised and I thought I better up my game... sit down and have good chat.”
Markle showed off a dazzling three-stone yellow-gold engagement ring, designed by Harry himself with a diamond from Botswana plus two diamonds taken from the personal collection of his late mother.
