As the thousands of spectators below – and the estimated two billion who will be watching on TV – look on, the couple are expected to share their first public kiss.
It's just one of several new details to emerge about the couple's nuptials this week.
On the morning of the wedding the 1,900 guests will begin arriving at Westminster Abbey at 8.30am – a full two hours and a half before the ceremony is scheduled to begin.
Showing them where to sit will be the historic Yeomen of the Guard (below) – the oldest military corps in existence and known as the Queen's bodyguards.
While the guests begin to take their pews, Kate will be getting ready at a secret hotel in central London where a team of stylists will be helping her.
But there is one thing that definitely will not become public knowledge until the last minute – details of the bride's dress.
These will be announced at 11.00am – the moment she arrives at the church with her father Michael.
Sources say she is adamant that nothing will stop her surprising William as she walks down the aisle.
Before Kate makes her entrance in a Fifties Rolls Royce owned by the Queen, the royals will have arrived and taken their seats.
They are expected to arrive between 10.40am and 10.50am, with the Queen and Prince Philip arriving last.
By this time, the monarch will already have announced what title she has bestowed upon the bride and groom. Some sources believe they could be known as the Duke and Duchess of Clarence or Cambridge.
Kate and her father will leave their hotel at 10.50am and travel down past Buckingham Palace, along the Mall and turn right at Trafalgar Square into Whitehall. They will then head into Parliament Square and turn right to Westminster Abbey.
Kate will make her grand entrance, and the ceremony will last for an hour and 15 minutes.
A5 12.15pm the newlyweds will leave the Abbey and retrace Kate's journey in a royal coach. Following them will be four ceremonial coaches filled with senior royals and Kate's parents.
After arriving at Buckingham Palace there will be private photographs taken by the official photographer Hugo Burnand, while 650 invitees make their way to the reception, taking place in 19 of the palace's opulent state rooms (pictured above) .
The Queen is hosting, and the couple's two cakes will be on display.
When the newlyweds step out on the balcony there will be a fly-past by the Battle of Britain Memorial Light of Lancaster, Spitfire and Hurricaine aircraft, followed by two Typhoon fighter jets and two Tornados.
At 3pm the couple will take a break – driving to St James's Palace for a short rest. They will return to Buckingham Palace at 8.00pm for their second reception – to which 300 people have been invited.
This private event for just close family and friends will feature the traditional toasts and speeches.
It's not known where the couple will spend the night, but they are expected to be setting off on their two-week honeymoon the next morning.
