Prince Harry and his fiancee Meghan Markle are due to marry at Windsor Castle in May.
The wedding will take place at St George's Chapel, Kensington Palace has confirmed. With capacity for just 800 people, the chapel is a smaller venue than Westminster Abbey, where Prince Charles married Diana and Prince William wed Kate Middleton.
However, despite being far more compact than some alternative venues, St George's Chapel has been a regular choice for Royal Weddings since King Edward VII used it in 1863 to marry Princess Alexandra of Denmark.
Prince Harry's uncle Prince Edward also got married there to Sophie Rhys-Jones in 1999.
Kensington Palace said Markle is to be baptised and confirmed into the Church of England before the wedding and she will also become a British citizen.
A spokesman for Prince Harry said the wedding "will reflect who they are as a couple" and it has also been revealed that they will plan the event themselves and involve members of the public.
The Royal couple's first official public engagement will be at an Aids charity on Friday (December 1) in Nottingham.
