According to the Telegraph, It has been a traditional venue for royal weddings ever since the future King Edward VII married Princess Alexandra of Denmark in 1863, according to The Telegraph.
The chapel can accomodate 800 guests – a much smaller venue than the 2,000-guest strong Westminster Abbey, where Prince William married Kate Middleton.
The palace also confirmed that the Royal Family will pay for the wedding, including the church service, music, flowers, and reception!
Markle, who is American, will become a British citizen, according to the palace. The notice also said that she is a Protestant, and will be baptised and confirmed into the Church of England before the service.
