The royal family are making final preparations for the wedding of Prince Charles and Camilla Parker Bowles which will take place on Saturday.
The wedding was originally set to take place on Friday, but the date was moved because of the Pope's funeral.
Guests will include Prince William and Prince Harry, Charles' brothers and sister and Camilla's children.
Grandmother Etta Richardson has already delivered the 20 cakes she baked for the wedding by special request.
The wedding ceremony will be held at Windsor Guildhall, followed by a blessing at St George's Chapel at Windsor Castle.
During this ceremony the royal couple will say a prayer where they acknowledge "sins and wickedness".
The prince will also promise to be faithful to his new wife.
The change in wedding day has caused problems for souvenir sellers who have found themselves with the wrong date on lots of mugs and tea towels.
One china shop in Kent solved the problem by crossing out the original date and painting on the right one.
Elsewhere a hotel room near the wedding venue reserved for Saturday sold on an internet auction site for five times its original price.
Those who can't get to Windsor will be able to watch people arrive by logging onto a webcam placed across the street from the Guildhall.
Visitors to theme park Alton Towers can also celebrate the couple's happy day by taking a trip on the renamed Camilla - Queen of Speed ride.
