Prince Harry will marry Meghan Markle in St. George's Chapel in Windsor Castle on the 19th May 2018.
The wedding service will begin at 12:00 and following the ceremony the newly weds will set of at 13:00 to travel by carriage through Windsor, where more than a 100,000 people are expected to gather to see the bride and groom and join in the celebration.
Since 1858 when Queen Victoria married Albert it has been a tradition for newlyweds to appear on the royal balcony, but with Windsor Castle not having a balcony this has been replaced with a carriage procession.
Prince Harry and his Bride will leave Windsor Castle in a carriage and travel along High Street through the town of Windsor, before returning to the castle by the Long Walk.
A statement from Kensington Palace said: "They hope this short journey will provide an opportunity for more people to come together around Windsor and to enjoy the atmosphere of this special day."
A Captain’s Escort from the Household Cavalry will escort the procession. A fitting choice as Prince Harry joined The Blues and Royals in April 2016 and served with the Household Cavalry Regiment, undertaking two tours of Afghanistan and rising to the rank of Captain.
